摘　　要：拔节期霜冻害是制约冬小麦生产的主要因素之一。然而关于冬小麦拔节期抗霜性的鉴定工作,国内外的研究报导还很少。选取了13个起源地和春化特性不同的小麦品种,通过利用人工霜箱模拟田间自然霜冻发生过程的试验方法,在小麦幼穗分化进程中的低温敏感期——药隔期进行抗霜性鉴定。同时,对这13个小麦品种越冬期间的抗冻性进行了鉴定。最后对冬小麦品种的抗冻性与抗霜性之间的相关性进行了分析。结果表明:抗霜性与抗冻性之间不存在显著的相关关系。抗冻力较强的冬性品种,抗春霜冻的能力不一定就强;相反,抗冻力较低、发育进程快的早熟品种也可能具有较强的抗霜性。Frost injury of winter wheat during its jointing stage has become one of the factors that restricting winter wheat production.But fewer studies on evaluation of frost resistance in jointing stage had been reported up to now. In this study,13 winter wheat varieties were selected as research materials,which differ in original place and ver- nalization characteristic.Frost resistance of those varieties were identified using an artificial frost chamber to simu- late natural frost at anther connective formation ...
