Evaluation of Drought Resistance for Hemarthria compressa at seedling Stage

摘要

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.
