摘要
本文通过对13种植物水分生理指标的分析,对其抗旱能力做了综合评定。研究结果表明,沙棘、沙打旺和山杏抗旱性最强,紫穗槐比较弱。进一步证实,组织束缚水含量对判别植物种的抗旱性具有重要意义。此研究可为黄土高原地区选择能源林植物提供抗旱性依据。
A comprehensive evaluation on the drought resistance of 13 plants was made by analysing water physiological indices. The result indicated that the species with the best drought resistance were Astragalus adsurgens,Hippophae rhamnoides and Armeniaca sibirica, Amorpha fruticosa was poor in drought resistance as compared with other species. It was further proved that the bound water content of tissue was significant in distinguishing drought resistance of a plant. The result would provide the drought resistance basis for selecting energy-forest plants in the Loess Plateau.
