摘要：

为研究无花果果实发育过程中ABA和乙烯含量与果实成熟的关系,以玛斯义陶芬(Masui dauphine)无花果果实为试材,对果实发育过程中呼吸速率和乙烯释放量及可溶性糖、淀粉和ABA含量进行了研究。结果表明:无花果果实发育分3个时期,第1个快速生长期(时期Ⅰ)、缓慢生长期(时期Ⅱ)和第2个快速生长期(时期Ⅲ),在缓慢生长期和第2个快速生长期之间为果实发育的转折期"始熟期"。始熟期后果实淀粉分解,大量积累葡萄糖和果糖,果实快速进入成熟期。无花果果实发育过程中ABA含量整体呈下降趋势,乙烯释放量随着果实发育逐渐增加,在始熟期和呼吸速率同步出现一个高峰。结果表明无花果果实是呼吸跃变型果实,乙烯诱导果实发生一系列生理生化变化,促使无花果果实成熟。
