Abstract

Production of medicinal plants and the use of methods to increase the production of active ingredient of its is a significant thing to enter the global market, currency and competition with other countries. The aim of this study was to investigate the changes in some morpho-physiological traits of German chamomile due to the application of three types of abiotic elicitors. In this study, chamomile leaves with different concentrations of elicitors were sprayed separately at three different weeks (6, 8 and 10) and then at two different times (48hours after solution and end of vegetative growth) leaf samples were collected and plant fresh and dry weight, chlorophyll a, b and total, carotenoids and protein were measured. The results showed that the highest amount of dry weight, total chlorophyll, carotenoids and protein with salicylic acid in both stages of growth at concentration of 250mM in the sixth and tenth weeks, with jasmonic acid in both stages of growth at concentration of 100mM in the sixth, eighth and tenth weeks and with methyl jasmonate at both stages of growth at concentrations of 50, 100 and 150mM in the sixth, eighth and tenth weeks was obtained. Comparison of the studied traits showed that the long-term effects of methyl jasmonate lasted until the sixth week, but the effects of jasmonic acid lasted until the eighth week and salicylic acid until the tenth week. Therefore, it seems that the long-term effects of salicylic acid are greater than jasmonic acid and this is better than methyl jasmonate.
