摘要: 本文对沙坡头沙区的12种锦鸡儿属植物的叶片解剖结构和水分生理等特征进行了比较研究,利用主分量,综合分析了与抗旱性有关的各个特征,客观地列出该属一些植物种的抗旱性顺序:白皮锦鸡儿>刺叶锦鸡儿>垫状锦鸡儿>狭叶锦鸡儿>柠条锦鸡儿>甘蒙锦鸡儿>绢毛锦鸡儿>中间锦鸡儿>小叶锦鸡儿>荒漠锦鸡儿>川西锦鸡儿>树锦鸡儿。供选择适宜的固沙植物种提供参考。

Abstract: In this paper 12 species of the genus Caragana Fabr.in the sandy area of Shapotou have been studied comparatively.The study includes leaf anatomy and characteristics of water physiology.By the principal components analysis on characteristics of the structures of leaf and water physiology, the order of drought resistance of these species is arranged.The order is C.leucophloea > C.acanthophylla > C.tibetica > C.stenopylla > C.korshinskii > C.opulens > C.hololeuca > C.intermedia > C.microphylla > C.roborovskyi > C.erinacea > C.arborescens.this order will provide a scientific evidence for selection of species in the work of revegetations of drifting sand.
