| 摘 要： | 以‘法兰地’草莓为试材,研究草莓果实生长发育过程中内源脱落酸(ABA)含量、FaNCED基因表达量的变化以及外源ABA、去甲二氢愈创木酸(NDGA)和乙烯利处理对果实成熟软化的影响。结果表明:在草莓果实成熟过程中ABA含量和FaNCED表达量出现2次高峰,分别是花后35d(转色期)和花后45d(果实完熟期)。外源ABA促进FaNCED基因的表达及ABA的积累,促进草莓果实的成熟和后熟软化,NDGA处理表现出相反效果,喷施乙烯利表现不明显,推测ABA在草莓果实成熟和后熟软化中可能起着重要作用。 |

| Abstract: | Changes on endogenous abscisic acid(ABA) content and FaNCED gene expression during fruit development,as well as the effects of exogenous ABA,nordihydroguaiaretic acid(NDGA) and ethephon applications on the ripening of strawberries(Fragaria ananassa Duch) were studied.The results showed two peaks of ABA content and FaNCED expression during the entire fruit development period,reaching their maximums at the fruit’s red ripening stage.The ABA application increased endogenous ABA and FaNCED gene expression promoting the fruit ripening and softening.On the other hand,NDGA delayed the fruit ripening and softening,while ethephon induced no significant effect. |
