芝麻不同时期打顶对种子产量和光合速率的影响
田间试验结果表明：在芝麻品种赣芝9号初花后24 d打顶可以获得最高产量,比不打顶（CK）增产11.8%;品质比CK好,瘪籽率比CK下降14.1个百分点;经济系数最高,综合效益好。较早期（初花后15 d和18 d）的打顶可以提高功能叶片的光合速率和叶绿素含量;后期打顶能消除空梢尖,从而有利于产量的形成。...

Institute of Grain and Oil Crops, Nanchang Academy of Agricultural Sciences in Jiangxi Province, Nanchang 330025, China; 2. Crop Research Institute, Jiangxi Academy of Agricultural Sciences, Nanchang 330200, China） The results of field test showed that： in comparison with no topping treatment, the treatment of topping on the 24th day after initial flowering of sesame variety Ganzhi No. 9 could obtain the highest yield and economic coefficient, and better quality and comprehensive benefit, its seed yield was increased by 11.8%, and its shriveled seed rate was decreased by 14. 1 percent. The early topping treatment （topping on the 15th or the 18th day after initial flowering） could enhance the photosynthetic rate and chlorophyll content of the functional leaves, while late topping treatment could eliminate t |
