Selection of Physiological Indexes of Drought-resistance to Acacia mangium
Weihua Zhang · 2005
In order to study the dominant factors that affect the drought-resistance of Acacia mangium,the author has determined on nine physiological indexes such as relative electrical conductivity rate(R_(EC)) and relative water content(R_(WC)),and analyzed the principal constituent of them with software SAS.The result of software SAS analysis indicates that R_(EC),R_(WC) and R_(WD),water factors to protect the stability of membrane,are main selections to determine the ability of drought-resistance,and another analysis of principal constituent mainly reflects the comprehensive action of adjustment to drought-resistance.
