摘　　要： 研究哈密瓜不同器官不同浓度水浸液对其种子萌发的自毒作用效应。结果表明,以根、茎、叶水浸液分别处理时,在浓度为10、50、90 g/L的范围内对种子发芽率和株高都表现了显著或极显著的抑制作用,随浓度增高抑制作用渐强;在浓度为90 g/L的范围内,茎、叶水浸液对单苗鲜重表现了显著的抑制作用;在同一浓度下,抑制作用叶>茎>根。和对照相比,种子发芽率在茎、叶水浸液浓度为10、50、90 g/L 3种浓度范围内都表现为极显著差异。 The autointoxication effects of water extract of Hami melon different tissues on seed germination were investigated.The results showed that water extract of root,stem and leaf had significant inhibiting effects on seed germination and plant height in concentrations of 10,50 and 90 g/L.And the higher the concentration was,the stronger the inhibitory effect was.Stem and leaf showed remarkable inhibiting effects on fresh weight in the concentrations of 90 g/L.The inhibiting effect of leaf was the strongest,followed by stem and root under the same concentration.Seed germination rates in 10、50、90 g/L of stem or leaf water extract treatments were significantly different from the control.
