Abstract: | The effects of jasmonic acid (JA), I-aminocyclopropane carboxylic acid(ACC) and 2-cholorethyl phosphonic acid (ethephon) on pollen germination wereinvestigated in strawberry cv. Tufts. ACC and ethephon stimulated pollengermination while JA was inhibitory. Pollen germination was decreased by 0.5mM JA from 42.5 to 5.8% compared with the control after4 h of incubation. On the other hand, ACC and ethephon (0.5mM) increased the pollen germination percentage to 55.6 and 60.7%,respectively. In addition, both ethephon and ACC relieved the inhibition ofpollen germination by JA. |
