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。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.
