- 摘要:
- 对不同掐尖时期大豆根瘤等生理指标的变化进行了研究。结果表明：不同掐尖时期对大豆的根瘤数、叶绿素含量有一定的影响，差异达到了显著或极显著水平，而对初花期(R1)和盛花期(R2)的植株鲜重、干重、根系鲜重等生理指标影响不明显。
- Abstract:
- The effect of different time of topping on physiological indexs of soybean was studiedThe results showed that there was a certain extent of nodule number and chlorophyll contentthe of soybean at different time of topping，and the differences between them have reached a significant or highly significant levelWhile plant fresh weight，dry weight，root volume and other physiological index had no significant effect at early flowering stage(R1)and flowering stage(R2)
