摘　　要：运用１４Ｃ示踪技术研究结果表明，叶枝同化产物的转运速率相当于果枝，但其转运量明显高于果枝。标记叶枝１４Ｃ同化物的再分配结果表明，分配到果枝蕾铃部分的光合产物相当于标记叶枝蕾铃的３００５％；标记果枝１４Ｃ同化产物再分配结果，分配到叶枝蕾铃部分只相当于标记到果枝蕾铃的０９３％。The study used^( 14) C trancer technique showed that the rate of labelling vegetative shoot transporting assimilates to fruit bearing shoot was conform to labelling fruit bearing shoot to vegetative shoot,and yet it's transportable amount was obviously high to labelling fruit bearing shoot.The redistribution of labelling vegetative shoot assimilates indicated that the proportion of assimilates which labelling vegetative shoot partitioned to squares and bolls on fruit bearing shoot corresponds to which on vegetative shoot by 30 05%,but the proportion of assimilates which labelling fruit bearing shoot partitioned to squares and bolls on vegetative shoot correspond to which on fruit bearing shoot by 0 93%.
