摘    要:以张家口市农业科学院培育的6个燕麦品种为试材,采用水、旱2种处理方法,研究了水分胁迫对燕麦生长的影响。并分别利用抗旱指数法和抗旱性隶属函数法,对参试燕麦品种的抗旱性进行了评价。结果表明:水分胁迫对燕麦生长和产量产生不利影响,但是不同品种对干旱的反应能力不同;利用2种方法评价的燕麦品种抗旱性顺序基本一致,其中坝莜3号和品5号抗旱性较强,坝莜6号抗旱性最差。该结果可为今后的燕麦育种工作提供一定的理论依据。

关 键 词:燕麦  水分胁迫  抗旱指数  隶属函数值  抗旱性

Abstract:Use six oat varieties bred by Zhangjiakou Academy of Agricultural Sciences as materials,the effect of water stress on oat growth was studied,and the drought resistance of oat varieties was evaluated using drought resistance index method and drought resistance membership function method.The results showed that water stress had unfavorable influence on the growth and yield.The oat varieties had different reaction ability to drought.The order of drought resistance evaluated by two methods was basically the same.The drought resistance of Bayou No.3 and Pin No.5 was stronger,and that of Bayou No.6 was the weakest.This research would provide a certain theoretical basis for oat breeding in the future.
Keywords:Oat  Water stress  Drought resistance index  Membership function value  Drought resistance
