Abstract
By means of a natural drought,four different kinds of stock seedlings grafted with Catalpa bungei cl.′Yu-1′ were put in pot culture within a drought stress environment,in order to determine,in a systematic way,the content of MDA, the protoplasmic membrane penetrability and the relative water content.Results show that the MDA content and the protoplasmic membrane penetrability of the four grafting stocks take on an increasing tendency and this tendency enjoys a same change;that between Catalpa bungei C.A.Mey stocks and Catalpa ovata stocks there is a remarkable difference in the MDA content;and that the relative water content decreases with the decrease of soil water content,the changing tendency of which is just contrary to the water saturation deficiency.A synthetic evaluation of the drought resistance of the four grafting stocks renders them from strong to weak as follows: Catalpa bungei stocksCatalpa bungei cl.′Yu-1′ stocksCatalpa fargesii stocksCatalpa ovata stocks.
