摘要
采用室内盆栽试验、盐胁迫下组培生根试验、盐胁迫下的膜透性测定及田间品种对比试验等方法对美洲黑杨辽育3号杨与胡杨杂种无性系及其亲本的耐盐碱性进行了试验研究。结果表明黑胡杨杂种无性系具有较强的耐盐碱性,能耐含盐量0.52%、pH 9.90的盐碱。
The salt alkali tolerance of Populus×deltoides ＇Liaoyu-3＇ and P.euphratica Oliv hybrid clone and their parents was studied by the methods of pot culture and tissue culture under salt stress as well as field experiment in this paper.The results showed that hybrid clones between P.Aigeiros Duby Section and P.euohratica Olv.had quite stronger salt-alkali toleranrance and could endure 0.52% salt content with a pH 9.90.
