摘要
对植被砼上的4个高羊茅(Festtuca arundinacea)品种Millenninm Ⅱ、Pearl、Millenninm和Barrington进行了高温、抽湿和高温抽湿处理,通过测定其株高、分蘖数、伤害比率、叶宽、叶色、根长、根冠比等7项指标,比较了品种间耐干热性的差异。结果表明:高温干旱对植被砼上高羊茅各品种生长发育造成了不同程度的影响;高温干旱双因子胁迫较之干旱或高温单因子更严重;Millenninm Ⅱ耐干热性最强,Millenninm最弱。
The morphological characteristics of 4 tall fescue(Festuca arundinacea) cultivars on vegetation concrete were investigated during heat stress,drought stress and heat-drought stress.The results showed that the plant morphogenesis was inhibited by heat-drought stress,specifically in tillers,leaf color,leaf width,the ratio of root to crown;Millenninm Ⅱ adapted to heat and drought stress in the four tested varieties,and Millenninm had poor heat and drought tolerance.
