摘　　要： 对‘妃子笑’荔枝同一穗上的早花果和晚花果的对比研究发现 ,各时期处于大体相同发育阶段的早花果鲜质量极显著大于晚花果 ,其果皮中GA1+ 3 、IAA和ABA的含量以及IAA/ABA的比值均低于晚花果 ,而ZRs含量和ZRs/ABA比值高于晚花果。据此认为 ,果皮中具有高的ZRs含量和ZRs/ABA比值与早花‘妃子笑’荔枝大果形成有关 。 Endogenous hormone levels in the pericarp and the fruit mass were comparatively studied between the fruits from early and late blooms on the same panicles of‘Feizixiao'litchi.The results showed that fresh mass of the early-bloom fruit was significantly larger than that of late-bloom, and contents of GA 1+3、IAA,ABA and IAA/ABA ratio in the pericarp from early-bloom fruit were lower than those from late-bloom fruit,whereas,ZRs level and ZRs/ABA ratio were higher during fruit development.It is suggested that higher ZRs level and ZRs/ABA ratio are associated with the formation of larger fruit size in early bloom,while higher IAA level and IAA/ABA ratio might be related to higher fruit set for the fruit from late bloom.
