| 摘 要： | 选取20个代表性的夏玉米品种,研究了根茎主要性状与倒伏性的关系。结果表明,夏玉米倒伏性与种植密度、茎秆拉力、茎秆穿刺力、茎粗和气生根层数具有显著或极显著相关性;密度、茎粗和穿刺力是影响茎秆倒伏的直接因素,可以作为衡量玉米倒伏的指标。

| Abstract: | Twenty summer maize hybrids that were planted widely in China were selected to study the relations of root and stem characters with lodging resistance.The result indicated that the planting density,stem pulling strength,stem puncture strength,stem diameter and support root numbers had significant relationship with lodging resistance.Planting density,stem diameter and stem puncture strength were the main direct-factors affecting the lodging resistance,so they could be used as the selection target for lodging resistance of maize varieties. |
