| 摘 要： | 以6个种源文冠果一年生幼苗作为研究对象,采用盆栽称质量控水的方法设置3个水分梯度,研究了不同种源文冠果幼苗在不同水分梯度上的水分生理特征及渗透调节变化规律,利用模糊数学隶属函数法对不同种源文冠果幼苗进行抗旱性综合评价。结果表明:随着干旱胁迫的加剧,不同种源的文冠果幼苗叶片含水量降低,渗透调节物质含量增加;通过对不同种源文冠果幼苗抗旱性的综合评价,种源间抗旱性由大到小依次为内蒙乌丹、新疆察县、山西汾阳、河北新华区、辽宁建平、河南陕州区。

| Abstract: | We studied the drought-resistance of six varieties of Xanthoceras sorbifolia Bunge.accessions from different provenances, designed three water gradients to study the water physiology and osmotic regulation response to water stress, and then valued it integrative with subordinate function.The seedling leaf water content was decreased and the osmotic regulation substances content was increased with the decrease of soil relative water content.By subordinate function analysis, the drought-resistance of six varieties was in the descending order of Wudan, Neimeng, Chaxian, Xinjiang, Fenyang, Shanxi, Xinhua area, Hebei, Jianping, Liaoning, and Shanzhou area, Henan. |
