In order to study the effect of plant growth retardants on potato microtuber production under stagnant liquid medium, a factorial experiment in a completely randomized design with three replications was carried out in biotechnology laboratory of agricultural faculty, Islamic Azad University, Sabzevar Branch. Experimental factors include four concentrations of chlorocholine chloride (0, 150, 300 and 450 mg l-1) and five concentrations of coumarin (0, 10, 20, 30 and 40 mg l-1). Results showed that stagnant liquid culture method used in this research can be successfully used for the production of potato microtuber. Use of chlorocholine chloride (CCC) and coumarin, improved potato microtuber production by reduction the time required to start microtuberization, increasing the number of microtuber per plantlet and increase the weight and diameter of microtuber. The shortest time to microtuberization and the maximum microtuber number per plantlets were obtained by application of 300 mg l-1 CCC and 30 mg l-1 coumarin. However, the highest average microtuber weight was observed at media containing 150 mg l-1 CCC and 10 mg l-1 coumarin. Therefore, application of 300 mg l-1 CCC and 30 mg l-1 coumarin for shortened the microtuberization time and application of 150 mg l-1 CCC and 10 mg l-1 coumarin for production of microtubers with more average weight can be recommended.

The main mechanism of action of herbicide Trifluralin is the inhibition of cell mitosis. As an important non-protein amino acid, γ-aminobutyric acid (GABA) contributes in certain physiological functions and stress tolerance. So, to detect the effect of Trifluralin and role of GABA on enzymatic activities and content of proline and growth substances including gibberellin (GA3) and cytokinin (6- benzyl amino purine) an experiment was conducted using squash (Cucurbita pepo) seedlings. Four levels (0, 5, 15 and 25 ppm) of trifluralin and presence or absence of GABA were applied in completely randomized design and in 3 replicates. Pots were sprayed by trifluralin 2 days after planting. Distilled water and GABA (500 µmol l-1) were sprayed on control and treated plants respectively 3 days after planting. Effect of trifluralin on ornithine amino-transferase (OAT), proline dehydrogenase (PDH) and content of proline and also GA3 and 6- benzyl amino purine was significant (p≤0.01) according to ANOVA. On the other hand, GABA had a significant effect on activity of PDH, content of proline and GA3 and cytokinin level. Content of proline and activity of OAT and the amounts of GA3 and cytokinin increased significantly, although PDH was decreased under influence of GABA. Content of proline and OAT activity were raised and GA3, benzyl amino purine and activity of PDH were declined by increased levels of trifluralin. Overall, it can be concluded that growth and biochemical indices of squash plants were improved by GABA under toxicity of herbicide trifluralin.

The use of wild germplasm and identification of resistant genotypes is an effective strategy to reduce the economic damage caused by the occurrence of fungal diseases in domesticated cultivars. In this study, three populations of wild apples in the west of Hyrcanian forest, Siahbil, Masal and Asalem were selected and the presence of resistance genes of two fire and powdery mildew diseases in trees were considered along an altitudinal gradients. After DNA extraction, screening for the presence of 9 resistance genes (six genes: Vf, Vr, Vr1, Vr2, Vm and Vbj and the three genes: Pl-1, Pl-w and Pl-d associated with Scab and powdery mildew diseases, respectively) was done. The results showed that all of the six genes studied in all three populations (except for the Vf gene in the Siahbil population) were present and the genes. Vr and Vf had the highest and lowest levels of presence in the studied trees, respectively. Also, for powdery mildew, Pl-d gene was observed in all three populations. Pl-w gene was present in some trees of Asalem population, while Pl-1 gene was not found in any of the trees. Our study showed the high prevalence of candidate genes for resistance to scab disease and the rare presence of candidate resistance genes to Powdery mildew in western populations of wild apple in Hyrcanian forest. This indicates a high vulnerability of the populations studied, especially populations located at lower altitudes in facing to an outbreak of powdery mildew in apple habitats.

Valerian is one of the most important herbs in Iran. Regarding the importance of this plant in traditional and industrial medicine, in this research, optimization of tissue culture, callus induction, and regeneration of whole plant from two types of leaf and petiole explants were evaluated on various hormone combinations. The results showed that the leaf segment is more suitable for callugenesis in both light and dark conditions. The highest amount of callus was obtained in light conditions for the leaf explant cultured on the medium containing 0.5 mg/L BAP and 1 mg/L BAP. Dark-induced calli did not show the potential to shoot regeneration on tested media containing different concentrations of BAP and TDZ, and only callus growth and root formation was observed. The light-induced calli from the leaf explants had a good potential to regenerate shoots on the regeneration medium. Maximum mean number of shoots was observed in the regeneration medium containing 3 mg/L BAP. These results provided basic information on the effects of some physical and chemical factors on the tissue culture and regeneration of Valerian. Also, we introduce an efficient system for shoot regeneration in this plant that can be used in molecular breeding programs using genetic engineering techniques.

Drought stress is the most prevalent abiotic stress in Iran and has highest negative effect on plant growth and productivity. Polyamines are plant growth regulators that enhance resistance of plants to environmental stresses such as water deficit. In this research, effects of putrescine + spermine with different concentrations of 0 + 0, 40 + 40, 40 + 60, and 60 + 40 µM (respectively) on some of the physiological characters of spring safflower under well-watering (100% FC) and limited-watering (40% FC) were studied. The experiment was arranged as factorial based on completely randomized block design with three replications in a greenhouse at the University of Tabriz. Without polyamines application, water deficit decreased growth parameters, leaf relative water content, photosynthetic pigments, and soluble protein in the leaves. Proline and soluble sugar contents of leaf increased under water deficit. Foliar application of 60 µM putrescine + 40 µM spermine improved most of these traits in the leaves, particularly underwater stress conditions. However, exogenous polyamines reduced leaf proline content probably due to increase in chlorophyll content. Reduction in compatible osmolytes such as free proline in root and soluble sugars in leaf with application of 40 + 40 and 40 + 60 µM of putrescine + spermine (respectively) could be due to polymines role as osmolyte as well as ROS scavenger. These results suggest that foliar spray of polyamines can potentially mitigate some of the harmful effects of drought stress and physiological performance of spring safflower.

In this study, the effects of drought on some physiological characteristics of winter and spring leaves of jasmin (Jasminum fruticans L.) were examined in plants grown in pots and treated with or without water stress for 25 days. Our results showed significant difference in pigment content and phenolic metabolism between winter and spring leaves of jasmine during spring season. In this study, winter leaves showed the higher Chlb, carotanoids, total phenol, flavonoids as well as phenylalanine ammonia lyase (PAL) activity, and relative water content (RWC) as compared to spring leaves, indicating winter leaves are sufficient in their capacity for non-photochemical energy dissipation via these mechanisms. However, water stress did not significantly affect these parameters. Drought significantly increased the amount of malondoialdehyde (MDA) and hydrogen peroxide (H2O2) following significant enhancement of peroxidase (POD) activity. However, in winter and spring leaves treated with water stress, decrease in the maximal quantum efficiency of PSII (Fv/Fm) was not statistically significant. In contrary, spring leaves exhibited a significant decrease in the performance index (PIabs) parameter under drought conditions. Notably, the kinetics of the OJIP chlorophyll fluorescence curve exhibited a quicker difference between winter and spring leaves of jasmine under well watered conditions. Thus, photosynthetic apparatus of winter leaves maintained a higher PIabs during spring season, and showed more tolerance to water stress by dissipating excess light energy by carotenoids; and by screening of photoradiation by phenolic compounds.

Storage proteins which found in seeds of many plants are studied in various fields such as human and animal nutrition, chemistry of protein, pharmacology, plant biochemistry and medicinal plants. The ability of these compounds to cause nutritional problems and toxic effects when used as foods has led to several studies on their dispersion in plants. In this research, seed proteins of wheat (Zarrin variety) have been extracted. The protein of interest was purified by ammonium sulfate precipitation method; dialysis and ion exchange chromatography. After purification by Fast protein liquid chromatography (FPLC), electrophoretic properties of this protein were investigated by Sodium dodecyl-polyacrylamide gel electrophoresis )SDS-PAGE( method. Inhibitory activity of this Protein against Bacterial alpha-amylase and human saliva were measured using the Bernfeld method. FPLC diagram illustrates the purification and collection of the desired protein. The electrophoretic pattern of this protein with relative mobility of 0.60 and 0.59 confirmed the purification process. Hydrolytic activity of bacterial and human saliva Alpha- amylase decreased by this protein 89.97% and 97.07% respectively. In general the isolation, purification and alpha-amylase inhibition property of this protein which extracted from wheat seed were confirmed in this study. Inhibition of bacterial alpha-amylase by this protein can be considered by agricultural researchers in biological control of parasites and pests. This alpha-amylase inhibitor can also be used to treat diabetes, digestive deficiencies and modify dietary regimens to reduce weight.

In order to investgate the effects of zeolite and DTPA on reproductive traits of tomato in soil contaminated with lead a factorial experiment in a completely randomized design with three replications in Masjed Soleyman city was conducted in 2015. Factors studied consisted the concentration of lead in four levels of zero, 50, 100 and 150 mg per kg of soil, zeolite in three levels of zero,0.5 and 1% and DTPA in three levels of zero, 50 and 100 mg per kg of soil. The effects of lead concentrations, the use of zeolite and DTPA significantly affected the length of inflorescence, number of inflorescences per plant, number of flowers per inflorescence and the number of fruits per plant. Also, the effect of lead concentration and interaction of zeolite and DTPA significantly affect fresh and dry weight of fruit. Spike length, number of inflorescences per plant, number of fruits per plant and fruit dry weight reduced about 60, 42, 34 and 49%, respectively by increasing the lead concentration in the soil compared with control. However, the use of zeolite and DTPA caused a significant increase in measured traits. Also, the use of higher concentrations of zeolite along with higher levels of DTPA increased fresh and dry weight of tomato fruits.

In order to investigate the effects of low water stress and nano potassium fertilizer on some vegetative and physiological characteristics of peppermint ,an experiment was conducted in greenhouse condition in 2014 as factorial based on randomized complete block design with three replications. Different levels of water deficit include: 100% field capacity (FC), 80% of field capacity (80% FC) and 60% of field capacity (60% FC) and four nano-potassium foliar application (control (no sprayed (T1), spray (T2:2/1000), (T3:4/1000), (T4:6/1000)) was applied. Plant height, number of tillers per plant, fresh and dry yield, weight percent of essential oil and oil yield, chlorophyll a, chlorophyll b , RWC, prolin and total soluble carbohydrates were measured. The results showed that with increase in application of nano-potassium fertilizer ,the plant height, number of tillers per plant, fresh and dry weight, yield and percent of essential oil , chlorophyll a, chlorophyll b , RWC, prolin and the total soluble carbohydrates increased. The effect of drought stress showed that control treatment (FC) was significant and account for the highest means without chlorophyll b, prolin and percent of essential oil. In general, with increasing drought stress, the essential oil percentage was added. The highest dry weight (4.81 g per pot), oils yield (7.52 g per pot) and total soluble carbohydrates (2.13 µg per g fersh weight) were obtained in foliar application in control, moderate stress and severe stress treatments, respectively. In total, nano-potassium spray application reduced the effect of dehydration stress.

According to previous studies, salicylic acid decreases the hyperhydricity in Thymus daenesis and this event might be due to the effect on polyamines metabolism. Polyamine oxidase enzyme catabolizes the polyamines in the cell and one of its byproducts is hydrogen peroxide (H2O2). Purpose of this study is analyses of salicylic acid effect on polyamine oxidase activity in thymus daenensis callus. In this study, the activity of polyamine oxidase, content of H2O2, and responses of enzymatic antioxidant including catalase and peroxidase was measured. Results showed that salicylic acid (concentrations of 10 and 20 µM) caused an increase in polyamine oxidase activity in a dose dependent manner. In callus under salicylic acid treatment (20 µM) a decrease in soluble peroxidase activity and an elevated H2O2 content was observed. Increase of H2O2 might be due to the influence of salicylic acid on polyamine oxidase and peroxidase activities. While variations in H2O2 levels resulted in no changes of catalase activity. Regulation of H2O2 level by salicylic acid through its effect on polyamine oxidase activity might contribute to ROS homeostasis, which is necessary for in vitro developmental processes in plant cells.

Karela (Momordica charantia), is one of the most commonly used vegetable that contains polypeptide-p and is used to control diabetes naturally. Polypeptide-p or p-insulin is an insulin-like hypoglycemic protein, shown to lower blood glucose levels in gerbils, langurs and humans when injected subcutaneously. Momordica Anti-HIV Protein (MAP30), alpha- and beta-momorcharins inhibit HIV replication in acutely and chronically infected cells and thus are considered potential therapeutic agent in HIV infection and AIDS. Related to these valuable properties, the present study outlines the in vitro callus induction of Momordica charantia which be fundamental for various purposes such as indirect regeneration, suspension culture or hairy root culture systems. The effects of the orientation of leaf explant, type of auxins and light conditions were evaluated on percentages of callus induction on MS basal medium. Results showed that the best callus induction (95.40%) was achieved when the leaf segments were culture up side on MS medium supplemented by 2 mg/l 2, 4-D and kept in dark condition for 1 week.

Fifteen populations of Damask rose were collected from important rose oil production regions of Kashan for evaluation of morphological variation. Fifty two quantitative and seventeen qualitative morphological characters were measured. Cluster and Principal component analysis (PCA) of morphological characters showed that the fifteen populations could be divided into two major groups including five subgroups. The variance analysis showed significant differences (P<0.01) among populations of Rosa damascena for 28 morphological characters such as stem length, leaf length and number of flowers per plant. Significant correlations were observed between different traits. The results are indicative of morphological variation among different populations of R. damascena from Kashan. Therefore, some of the traits such as number of flower per branch and number of flowers per plant, which showed a positive strong correlation in this study, or the number of prickle can be used as significant and important attributes in determining the criteria for the evaluation and selection of populations. The essential oil content (w/w) of flowers was assayed after extraction in Clevenger apparatus. Correlation results showed that there is a significant relationship between some morphological characters and essential oil content. Stipule length had a significant positive correlation with the essential oil content, while a significant negative correlation was observed for pedicle length and receptacle glandular length with the essential oil content.

In this study, population of Chenopodium album were collected from four geographical directions such as east, west, north and south of summer crop of Gonbad Kavous. Then 10 plants from each direction at least with 100 m distance were collected and at the end leaves below the inflorescence of plants were selected. Collected leaf samples of each direction were tested for epidermal characteristics study and metabolites of plant. Epidermal traits of leaf stomata such as type, epidermal cells form, anticlinical wall type, length, width and area, the number of epidermal cells, index and density as well as content of starch, protein, soluble sugar and total phenols of chenopodium album were measured. Results showed that whole population of Chenopodium album in various directions had stomata in both surface of upper and back. The highest number of epidermal cells and stomatal index and density of Chenopodium album in various directions except in case of epidermal cells number in south were allocated to back surface of leaves. Stomata type and epidermal cells form on both surfaces of studied directions were animistic and irregular respectively. Chenopodium album in both leaf surfaces in different directions except south had anticlinical wall type a slightly undulating. The highest starch, protein, soluble sugar and total phenols in Chenopodium album were obtained in west, south, east and east respectively. Therefore, knowing the characteristics of stomatal cells, the compromise osmolytes of soluble sugar as well as phenolic compounds due to impact of the opening and closing of stomata and transpiration

On metal contaminated soils, ectomycorrhizal( ECM) fungi may improve plant growth through an enhanced nutrition or by alleviation toxicity of the metals. In order to evaluation of alleviating effects of ectomycorrhizal colonization on zn toxicity, a study was performed using pistachio plants and Agaricus bisporus fungus as factorial in a completely randomized design with three replications. The experiment included two factors: mycorrhizal (M) and non-mycorrhizal (NM) pistachio plants and five levels of the zn concentrations (0, 30, 60, 90 and 120 μm) in 3 replicates. In this study experiment was conducted to investigate the effect of ectomycorrhizal colonization in the alleviation of oxidative stress and improvements of the antioxidant enzyme activities, lipid peroxidation and metal accumulation in pistachio trees (Badami cultivar).The results showed that the increase of zinc concentration caused an increase in the malondialdehyde (MDA), and induction in antioxidative enzymes activity in the leaves of the M and NM plants, but it was dramatically more in M plants. A decrease of ascorbate (ASA) content was induced by increasing the zinc concentration where it was higher in M plants but all metal treatments increased dehydroascorbate (DHA) contents in both M and NM plants. The results showed that the Zn translocated from root to shoot in M plants was lower than NM plants. The amelioration of Zn toxicity by A.bisporus may be a result of improving the antioxidant defense system and prevent the absorption of heavy metals.

Wild relatives which constitute the crop gene pool, have an inseparable role in construction of new breeding programs. The present study aims to compare diversity of leaf water content, excised leaf water rate specific leaf area, flavonoids, total phenol and protein content traits among three annual wild chickpea species (Cicer echinospermum, C. reticulatum and C. bijigum) with cultivated one (C. arietinum).With this purpose an experiment including 10 treatments and 4 repetition was conducted in Randomly Complete Design at greenhouse in National Plant Gene Bank of Iran during 2014-15. Significant difference has been observed between genotypes from all measured biochemical and physiological traits point of view. Relative water content and leaf relative water loss in C.arietinum statistically was similar to C. reticulatum and C. echinospermum Relative water content of C. bijigum significantly was lower than other species. While leaf relative water loss in this species significantly was more than other species. Average of protein amount was 21% in C.arietinum and C. bijigum, 18% in C. reticulatum and 17% in C. echinospermum. Minimum amount of specific leaf area and maximum amount of total phenol content was found in C. bijigum. There was a considerable variety between C. reticulatum genotypes from flavonoids and total phenol content point of view, which can be used for further achievement in breeding programs for providing functional food or introduction of resistance genotype to pest and disease.

Algae have various applications and may use to biochar production. In this study, laboratory biochar production of two macroalgae of Enteromorpha compressa and Ulva lactuca collected from Persian Gulf were investigated. Biochar production was performed at different temperature without oxygen. The characters of obtained biochar were determined by standard methods. Results showed that the temperature had significant effect (P<0.05) on weight, pH, organic carbon content, N, Ca, Mg, Na and K of macroalgal biochars. The biochar of E. compressa and U. lactuca had, respectively, 13.54 -28.57 % and 22.65-43.75 % ash weight; 8.04-11.71 and 8.17-12.09 pH; 9.1-18.22 % and 12.14-21.25 % organic carbon; 2.1-3.3 % and 2.7-4.1 % N; 16-20 and 20-32 meq/l Ca; 48-172 and 12-440 meq/l Mg; 26485-33531 and 7977-13445 meq/l Na; 7323-8831 and 4675-7933 meq/l K. The macroalgae biochar have different nutrients that could be used for improvement of soil and increasing of yield of production. In addition, biochar of of E. compressa and U. lactuca may use for improvement of acidic soils and also as biosorbent for treatment of wastewaters.

Forest trees are considered as most important and huge carbon pools in the forest ecosystems and have a great influence on the reduction of carbon emission in the atmosphere. Therefore, how to measure and estimate the carbon stored in the trees in the forests are the main issue for ecologists. The aim of this study was to estimate of leaf biomass and leaf carbon sequestration of Cercis siliquastrum L. in Arghavan forests reserves of Ilam. For this purpose, 30 trees were selected using random sampling method and height, mean diameter of crown, number of sprout and crown length variables were measured. All leaves of 1/4 crown area were collected. After of drying, dry weighted of leaves calculated. Enough quantity of leaves (1 gr samples) was burned in electrical kiln to calculate the carbon storage. To calculate of leaf area index was used gravimetric method. Mean tree method was used to generalize the result to the whole forest. Based on results, mean of leaf biomass, mean of leaf carbon sequestration and mean of atmosphere CO2 absorption were 53.55, 23.4 and 86.02 kg per hectare, respectively. Mean of leaf area index in studied area was 0.058. The results of allometric using of linear regression showed that there was a significant and positive correlation between mean diameter of crown and leaf biomass, carbon sequestration and leaf area index variables in the studird area.

Regarding the harmful side effects of chemical insecticides, currently the uses of the plant extracts have been considered. The potato tuber moth, Phthorimaea operculella Zeller is an important pest of potato in the fields and stores especially in tropical and subtropical regions of the world. The damage of this pest in stores is more serious than the fields. In this research the extracts of four different medicinal plants including: eucalyptus, Eucalyptus camaldulensis Dehn., lemon balm, Melissa officinalis L., Acanthophyllum bracteatum Boiss. and rampion, Heracleum persicum Desf. Were studied in the growth chamber set at 25±2˚C, 65±5% RH and photoperiod of 14 light and 10 dark hours. In the study of ovicidal effects, the LC50 in eucalyptus and rampion were 7.07 and 6.95%, respectively. In the study of first instar larval penetration, it was found that all the extracts were significantly lower than the control. In oviposition inhibition test, it was found that all the plant extracts have significantly reduced the oviposition of the potato tuber moth. In the fumigant effect experiments, there was no significant difference between the plant extracts and the control. Therefore it was concluded that none of the plant extracts have fumigant effects on different life stages of the potato tuber moth. Therefore, it can be concluded that eucalyptus and rampion extracts can be used to control the composting of potato tuber moth due to the appropriate controlling effects on this pest.

Matricaria aureais an important medicinal plant belonging to Asteraceae, the widely used in the phrmacetical, food and cosmetics industrial. According to importance of this plant, the aim of current study was optimizing tissue culture in Matricaria aurea. In order to optimize of tissue culture two experiments, callus induction and indirect regeneration were carried out. These experiments were laid out in factorial arrangement based on completely randomized designs (CRD) with three replications on MS base medium. In these experiments, various levels of plant growth regulators, NAA (0, 0.5, 1and 2 mg/l) and BAP (0, 0.5, 1and 1.5mg/l), with two explant types (stem and leaves) were compared. The results showed that was not observed in growth hormone-free medium (control). Results showed that callus induction was occurred fast in all explants in combination of NAA (0.5 mg/l) and BAP (1 mg/l). The best combinations of plant growth regulators for callus induction were 0.5 mg/l NAA + 1 mg/l BAP and 1 mg/l NAA + 1 mg/l BAP for stem and leaves (100%) respectively. Interaction of different concentration of NAA and BAP was significant for callus diameter trait and leaf explant in combination of 2 mg/l NAA + 1.5 mg/l BAP was the highest callus diameter with mean of 15.31 mm. We observed maximum of indirect regeneration percentage (85.59%) in calli derived from leaf in medium with 0.5 mg/l NAA + 1 mg/l BAP.
