- 摘要:
- 以大豆品种合丰50为试验材料，采用灰色关联度的方法，研究掐尖处理后主要农艺性状对产量的关联度大小。结果表明：在掐尖处理中，产量与主要性状的关联度大小依次为单株粒重>有效荚数>百粒重>株高>分枝数>主茎节数>单株粒数；在不掐尖的情况下，关联度顺序为株高>单株粒数>单株粒重>百粒重>有效荚数>主茎节数>分枝数。
- Abstract:
- Taking Hefeng 50 as experiment materials，the correlation degree of main agronomic traits and yield after topping was studied by grey correlation degree analysis.The results showed that in topping treatment，the correlation order between agronomic traits and yield was as follows:seed weight per plant >effective pod number>100-seed weight>plant height >branchs number>main stem node number >seed number per plant，in non topping treatment，it was follows:plant height>seed number per plant >seed weight per plant>100-seed weight>effective pod number>main stem node number>branchs number.
