摘要: 对金昌市新引进的30种植物进行了PV曲线主要水分状况参数的测定,以抗旱性指数大小为基础,结合束缚水与自由水的比值,分析了引种植物的抗旱性,通过植物叶水势、相对水分亏缺及细胞弹性模量的分析,提出了初步种植建议。

关键词: 引种植物, PV曲线, 抗旱性

Abstract: Under the natural conditions,the main water parameters of 30 species plants newly introduced into Jinchang city were determined by using pressure-volume(PV) technique,and the drought resistance indexes of those plants were ranked in an optimum order by the values of drought resistance indexes,ratio between bound water and free water.Futhermore,the leaf water potential,reletive water deficits and bulk elastic modulus(ε) have been analyzed,23 species plants were selected with planting measures.

Key words: introduced plant, pressure-volume technique, drought resistance index
