摘要
用赤霉素处理日光温室黄瓜果实，与对照株进行黄瓜光合产物运输及分配的比较研究。结果表明：赤霉素能加速黄瓜功能叶片中光合产物的输出，使黄瓜植株各器官１４Ｃ光合产物分配比例发生改变，由茎＞果实＞根转变为果实＞茎＞根，从而与春季黄瓜叶片同化物分配比例一致，然而处理株与对照株功能叶片中１４Ｃ光合产物输出比例差别不大，也就是说赤霉素处理并不影响功能叶片１４Ｃ光合产物的输出总量，而是影响已输出的１４Ｃ光合产物在植株其它部位的分配比例。
The effects of gibberellin
on cucumber fruits in solar green house was studied in this experement.The result showed that
the gibberellin can accelerate the transportation of the 14 C photosynthate of cucumber
leaves and change the distribution of 14 C photosynthate of cucumber leaves,from
stalk>fruit>root to fruit>stalk>root ,but can not influence the transportation
ratio.namely,Gibberellin can influence the distribution of photosynthate of cucumber leaves,but
can not influence the amount of transported photosynthate.
