| 摘 要： | 研究了不同整枝方式下（双干整枝、三干整枝、四干整枝），日光温室彩色甜椒不同叶位叶片光合、蒸腾作用参数的变化及
其植株不同器官干物质的分配规律。结果表明，3种整枝方式下，叶片净光合速率（Pn）、气孔导度（Gs）、气孔限制值（Ls）、蒸
腾速率（Tr）和单叶水分利用效率（WUE）随叶位的降低而下降，其中Pn的下降是非气孔限制的结果。与双干整枝相应叶位比较，三
干整枝、四干整枝的上位叶、中位叶具有较高的Tr和较低的WUE；三干整枝、四干整枝的下位叶的Tr小于双干整枝下位叶，但WUE高于
双干整枝。3种整枝方式下全株中果实的干物质分配比例均为最高，达50.88 %~60.26 %，其次为茎和叶，向根的分配比例最低。三干
整枝和四干整枝的单株产量和单果质量显著高于双干整枝。

| Abstract: | This paper studied the effects of 3 pruned methods(2 stems,3 stems and 4 stems pruned method)on photosynthetic gas exchange parameters,transpiration and distribution pattern of assimilate.The result showed that net photosynthetic rate(Pn),stomatal conductance(Gs),stomatal limitation value(Ls),transpiration rate(Tr)and water use efficiency(WUE)were in upper leaves>in middle leaves>in lower leaves under 3 pruned methods.In middle or lower leaves the decrease of Pn was considered as a result of non-stomata restriction.Compared with 2 stems pruned method,the Tr in upper or middle leaves,and WUE in lower leaves of 3 or 4 stems pruned method increased.Under 3 pruned methods,the distribution pattern of assimilate to fruits was the highest,the next was to stems and leaves,and the distribution of assimilate to root was the lowest.Compared with 2 stems pruned method,per plant yield and weight of single fruit of sweet pepper were significantly increased under 3 or 4 stems pruned method. |
