摘要
本文阐述了用盆栽试验对比研究8个冬麦品种在苗期根系生长发育特点,结果表明,不同品种单株次生根数、单株根干重和根冠比均存在明显的差异。通过比较分析不同土壤水分条件下的各品种单株性状,可得出有发达根系系统的品种抗逆性较强。
Results from pot experiment showed that there are obvious differece in secondary root number,root dry weight and root:shoot ratio among different winter wheat varieties. By comparision of root and shoot characters of different varieties under different soil water conditions it can be concluded out that varieties with well developed root system have strong resistance to adverse circumstance.
