Effects of simulated acid rain on seed germination and seedling physiological characteristics of X Triticosecale

Abstract

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
