The cause of hindering the gynospore formation was short of boronin chestnut orchard,which led to the poor pollination and a decrease ofendogenous GA1/3, iPAs level and an increase of endogenous ABA level in ovary,which restrained the mother cell division of gynospore.The low level ofendogenous GA1/3,iPAs contents and the increase of endogenous ABA contentcaused a serious lack of reducing sugar,starch,protein and potassium in ovary,which led to a cease of young embryo development.
其中,大孢子形成过程的停滞是由于栗园B素缺乏,致使授粉不良和子房内源GA1/3、iPAS等含量下降,ABA含量上升,从而抑制大孢子母细胞分裂;幼胚发育停滞则是由于子房内源GA1/3、iPAS等生长类激素的上升启动受阻,继续处于低水平,ABA上升,使子房中还原糖、淀粉、蛋白质和K素积累受阻,造成营养严重缺乏。
