摘要: 以小黑麦品种中饲237为材料,在不同pH值的模拟酸雨条件下对种子萌发及幼苗生理特性进行了研究。分别测定了发芽率、发芽势、发芽指数、活力指数和种子脱氢酶含量、幼苗鲜重、幼苗叶片叶绿素含量、叶片电导率等指标。结果表明,种子的各项发芽指标及种子脱氢酶含量、幼苗鲜重、叶绿素含量等随酸雨pH值减小整体呈降低趋势,叶片电导率则随酸雨pH值减小而有增加趋势.

Abstract: Efects of simulated acid rain on seed germination and seedling physiological characteristics of X Triticosecale.(Zhongsi 237) were studied.The indexes of germination,seed dehydrogenase,fresh weight and chlorophyll content of seedling,and permeability of plasma membrane were tested.The results indicated that the indexes of germination,seed dehydrogenase,fresh weight and chlorophyll content of seedling decreased with pH decrease,while the permeability of plasma membrane increased with pH decrease.

Key words: Poplar tree, Fine root, Biological cycling, Dynamics change
