Effect of Cerium on Seed Germination under Acid Rain Stress

摘要

Effect of Ce on barley seed germination under acid rain stress was studied. The experiment results show that the seed germination percentage, germination viability, dry weight of seedling and chlorophyll content decrease with increasing pH value, but root membrane permeability increases with decreasing acid rain pH value. Ce can re- duce the acid rain stress when barley seed is soaked with Ce. It indicates that Ce mitigates the germination by acid rain inhibition of seed.
