1·The suitable seed harvest time is 5 th week after tasseling.
适宜的收种时间为抽穗后第5周。
2·The results showed that drought stress reduced leaf area, plant height and the yield of corn in jointing to tasseling stage;
结果表明，拔节至抽穗期缺水抑制叶面积的扩展，造成植株矮小，产量降低；
3·Owing to water stress on corn, the grains per panicle, mass of 1000-grain and yield of corn was decreased in tasseling to filling stage;
抽穗至灌浆期胁迫影响制种玉米库容建立，籽粒小、千粒质量低； 持续或交替水分胁迫严重抑制叶龄进程，显著降低产量；
4·As the maize development in tasseling and flowering, the peroxidase zymogram in the male sterility line significantly differed from that in the maintainer and restorer line.
玉米抽雄期和开花期的不育系与保持系、恢复系叶片中的酶谱差异明显。
