| 摘 要： | 利用塑料管栽培方法,对15个黄淮海地区推广的小麦品种进行了根系对水分反应的研究。结果表明,这些品种的根系对水分反应不同。用聚类分析法可将品种分为正敏感型、不敏感型、较敏感型和负敏感型4种类型。品种的抗旱指数与根系反应没有明显的相关性。

| Abstract: | The response of root to water was studied on 15 varieties of winter wheat,using plastic tube method.Results indicated that the varieties could be classified into four types upon response of dry weight of root.They were positive sensitive type,non-sensitive type,less sensitive type and negtive sensitive type.There was no correlation between drought resistance index and responses in 15 vareitses of winter wheat. |
