摘　　要：韭菜的植株生长和抽薹开花与叶片净光合速率之间存在着协调的“库—源”关系。韭菜的收割适宜间隔期应不少于25天。韭菜在生长过程中不同叶位的叶片光合能力呈现从幼龄向成熟方向发展的趋势。生产上应选用单株平均净光合速率、叶绿素含量、单株总叶面积和单株平均比叶重均较大的品种。本试验中以津南青韭为最佳。The results showed that there were coodinating sink-sonce relationships between net photosynthetic rate and growth of leaves or that of pedicel in Chinese Chive. The suitable harvesting interval in Chinese Chive should be not less than twenty five days. Photosynthetic capacity appeared to be the tendencies developing from young to mature during growth or in the leaves of various positions. The cnltivar which has higher average net photosynthetic rate of the whole plant, chlorophyll content, leaves area of the whole plant and average specific leaf weight (SLW) of the whole plant ought to be selected for the cultivation. Jin nan Qingju is the best one among the cultivars in the experiment.
