摘要
为了探明李树水分逆境生理,在干旱胁迫条件下,通过对紫叶李和长李15某些生理生化指标的研究,探讨水分亏缺时李树抗旱的生理反应及其适应机理。结果表明:随着干旱胁迫程度的加强,两种李树的过氧化物酶(POD)和过氧化氢酶(CAT)活性均表现为先升高,再降低;而丙二醛(MDA)的含量显著提高。品种间表现为干旱胁迫对紫叶李的伤害大于对长李15的伤害。
In order to prove plum tree water stress physiology, the physiology reaction and its mechanism with water deficit in plum were discussed through analyzing the physiological biochemistry characteristic comparison of Long plum 15 and Prunu cerasifea under drought stress. The results indicated that： with drought stress strengthen, two kinds of plum trees peroxydase（POD） and catalase （CAT） activities first raising and then dwcreasing,but the malonaldehyde（MDA）Content increased remarkable. The injury of drought stress to Prunus cerasifera was heavier than to the Long plum 15.
