Özet

The effects of jasmonic acid (JA), I-aminocyclopropane carboxylic acid (ACC) and 2-cholorethyl phosphonic acid (ethephon) on pollen germination were investigated in strawberry cv. Tufts. ACC and ethephon stimulated pollen germination while JA was inhibitory. Pollen germination was decreased by 0.5 mM JA from 42.5 to 5.8% compared with the control after 4 h of incubation. On the other hand, ACC and ethephon (0.5 mM) increased the pollen germination percentage to 55.6 and 60.7%, respectively. In addition, both ethephon and ACC relieved the inhibition of pollen germination by JA.
