Abstract
Experiment was conducted with the leaves of 3 cultivars of 3-year-old apricot Armeniaca vulgaris under soil drought stress in field conditions .The effects of soil drought stress on physiological and biochemical characteristics of apricot were studied .The results were as follows :(1)Chlorophyll fluorescence parameter (F v/ Fm), leave relative water content (LRWC) and indole-3-acetic acid (IAA)content decreased , and cell membrane permeation , soluble sugar content , proline content (Pro)and superoxide dismutase (SOD)activity increased under stress .(2)With the decrease of soil relative water content (SRWC), correlation among parameters lowered .(3)The drought-resistance of 3 apricot cultivars was different under different water treatments .When the soil drought stress was comparatively low , their drought-resistance could be ranked as follows :Jintaiyang Xiangbai Jinhuanghou ;it was Xiangbai Jintaiyang Jinhuanghou under higher stress .[ Ch , 9 tab .8 ref .]
