摘要
本文通过对玉米植株进行剪叶处理来研究玉米不同部位叶片对玉米籽粒产量、百粒重、果穗重的相对影响率（或贡献率）。结果表明，玉米在授粉完成后，除剪去全部叶片外，剪去其它部位叶对穗长、穗粗、穗轴粗、穗粒数的影响不显著；对籽粒灌浆速率影响最大的是棒三叶；对籽粒产量、百粒重和果穗重相对影响率的大小顺序为：上部叶片〉棒三叶〉下部叶片。
Through the experiment of leaf cutting,the article analysed the influential rate of different parts of maize leaves on the corn production, hundred-grain weight and grain ear weight.As the results suggested, after the pollination had been finished, the influence of leaf cutting to the length and thickness of maize ears ,the diameter of spike-stalk and the kernels per spike were minimized.Furthermore, the experiment revealed that the third leaf was the most influential one on the maize ; while the influential sequence could be arranged as ： upper leaves 〉 the third leaf 〉 bottom leaves.
