Abstract
The bungeic A.Mey was grafted in four stocks including Catalpa ovata Don,Calpa fargesii Bur and others.And the experiment in the drought stress to four types of grafted nursery plants was conducted in potted condition,the physiological and biochemical effect such as the activity of SOD,lipid membrane permeability,the reaction of the peroxide accumulation and cell osmoregulation substance was analyzed.The results showed that:the activity of protective enzyme SOD was increased after the first drop,which was evidently showed in bungeic A.Mey.The accumulation of MDA was increased significantly and the largest accumulated amount was in grafted nursery plants with Catalpa ovata Don.The lipid membrane permeability had various increasing degrees and the grafted nursery plant with Catalpa ovata Don and Calpa fargesii Bur expressed faster increasing degree of lipid membrane permeability and less in bungeic A.Mey.The soluble protein content was in varying degree,and more appeared in bungeic A.Mey.After the comprehensive analysis of variance of several physiological indices,it was thought that the grafted nursery plant with bungeic A.Mey had strong resistance to drought.
