摘要：

本文研究哈密瓜自毒作用对幼苗生长和生理生化作用的影响。结果表明：以不同浓度的叶水浸液分别处理时，对幼苗根长和发根数具有抑制作用，随着浓度的增高，抑制作用逐渐增强，和对照相比，在浓度为50/L、90/L时达到显著或极显著水平；而对株高和幼苗鲜重则具有促进作用。经幼苗生理生化测定，叶绿素a、叶绿素b、类胡萝卜素含量随水浸液浓度升高而显著下降；过氧化物酶在水浸液浓度为50g/L时活性最高，之后随水浸液浓度增高而逐渐下降。

Abstract:

The Autointoxication effects of water extract of Hami melon’s Leaf on seedling growth were investigated. The results showed that leaf water extract had some inhibiting effects on root length and the root number of Hami melon in concentrations of 50/L 、90/L and the inhibiting effects were strengthened with increasing of water extract concentration. Leaf water extract had some promotion effects on plant height and green weigh in concentrations of 50/L、90g/L; Comparedwith controls，the content of chlorophyll a, chlorophyll b and carotenoid all significantly were decreased with increasing of water extract concentration.
