摘要
本试验以先玉335和农大364为试验材料,于吐丝期对其进行剪1/4叶片、2/4叶片、3/4叶片和剪2/4穗等减源和减库处理,研究改变源库关系,源库调节对玉米子粒产量及相关性状的影响。结果表明:源库变化对先玉335子粒干重和产量的影响均为源>库;对农大364为库>源。
In this experiment, the maize varieties ＇Xianyu 335＇ and ＇Nongda 364＇was chosen as the test materials. 1/4, 2/4 and 3/4 of leaves were cut off and 1/2 of the spikes were cut off to study effects of changes of source and sink on yield and related characters of maize. The results showed that effect of reducing source was greater than reducing sink on dry grain weight and yield for ＇Xianyu 335＇. On the contrary, that effect of reducing sink was greater than reducing source on dry grain weight and yield for ＇Nongda 364＇.
