ABSTRACT:
Applying the method of subordinate function, nine physiological drought resistance indexes of 3 species were measured and a comprehensive evaluation on drought resistance of them was given. The results showed that the drought resistant capability decreased in order of Tamarix ramosissima Ldb., Platycladus orientalis and Sympegma regelii. Applying the method of grey correlative analysis, the correlation of drought resistance and drought resistance indexes was analyzed. The results with grey correlative degree analysis showed that chlorophyll content, water potential of leaves, relative water content and electric conductivity can be regarded as the important indexes of drought resistance evaluation of the species.
