乌兰布和沙漠地区不同沙生灌木的耐盐性综合评价
Comprehensive evaluation on salt tolerance of different desert shrubs in Ulan Buh Desert regions
摘要
Abstract
Based on the principal component analysis, the cluster analysis and the membership function method, a pot experiment was conducted to evaluate quantitatively salt tolerance of the seedlings of Nitraria tangutorurn, Nitraria sibirica, Zygophyllurn xanthoxylon, Ammopiptanthus mongolicus, Caragana korshinskii, Reaurnuria trigyna and Tamarix austrornongolica growing in the Ulan Buh Desert by measuring many morphological and physiological indices. This study proposed that the ground diame- ter, stomatal conductance, water use efficiency, water potential, branch length, above dry weight, main root length, lateral root length, lateral root number and root diameter were considered as the important indicators of salt-tolerance evaluation for the hese desert shrubs. Seven shrubs were divided into strong, medium and weak salt tolerance, in which the R. trigyna and the T. austromongolica were strong, and the N. sibirica and N. tangutorum was medium, and the others were weak. The salt tolerance of seven desert shrubs was in order as R. trigyna〉 T. austromongolica 〉 N. sibirica〉 N. tangutorum 〉 A. mongolicus Z. xanthoxylon〉C. teorshinshii.关键词
