EFFECTS OF SOME PLANT GROWTH REGULATORS ON JASMONIC ACID INDUCED INHIBITION OF SEED GERMINATION AND SEEDLING GROWTH OF BARLEY
Abstract
The effects of gibberellic acid, kinetin, benzyladenine, ethylene, 24- epibrassinolide and polyamines (spermine, spermidine, putrescine, cadaverine) on jasmonic acid inhibition of seed germination and seedling growth of barley were studied. All of the plant growth regulators studied were determined to have a succesful performance in reversing of the inhibitory effects of jasmonic acid on the seed germination and seedling growth. Moreover, the above mentioned growth regulators overcame the inhibitory effect of JA on the percentages of germination and coleoptile emergence in the same ratio, while GA3 was the most successful hormone on the fresh weight and radicle and coleoptile elongation in comparison with the other growth regulators.
