摘    要:以3年生杏树Armeniaca vulgaris叶片为试材,采用田间试验的方法,研究土壤干旱胁迫对3个杏树品种生理生化特性的影响.结果表明:①土壤干旱胁迫下,叶绿素荧光参数(Fv/Fm)、叶片相对含水量和吲哚乙酸质量分数下降;叶片相对电导率、可溶性糖质量分数和脯氨酸质量分数和超氧化物歧化酶活性上升.②随土壤水分的降低,因子间相关性逐渐减弱.③3个品种的抗旱性随土壤水分的不同而有异.胁迫程度较轻时,抗旱性依次为:金太阳>香白>金皇后;随胁迫的加剧,抗旱性则为:香白>金太阳>金皇后.表9参8

关 键 词:植物生理学    土壤干旱胁迫  生理生化特性

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/F_m),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.]
Keywords:plant physiology  Armeniaca vulgaris  soil drought stress  physiological and biochemical characteristics
