Paper Abstract

Under the controlling of water, the drought tolerance of twenty H. compressa was comprehensively evaluated with the method of membership function using 8 indices including the relative plant tall, relative production. The result of tolerance order showed that: 'Guangyi'> H027 > 2002-4 > H042 > H054 > 2003-5 > H055 > H002 > H035 > 2003-1 > H050 > 'Chonggao'> H031 > H047 > H043 > H033 > H036 > 2003-4 > H019 > H029. Furthermore, the correlation analysis between the tolerance and indices showed that there was a significant correlation between the tolerance and relative production, electrical conductivity, water content.
