Abstract
The seeds of two Medicago sativa varieties were soaked with different Ca2+ concentration to study effects on seed germination,fresh seedling weight,dry seedling weight and seed vigor under the simulated aid rain stress for screening the optimum Ca2+ concentration to tolerate acid rain stress for Medicago sativa.The results showed that the germination rate,fresh seedling weight,dry seedling weight,germination index and simplified vigor index of two Medicago sativa varieties treated with 5mmol/L Ca2+ solution were very significantly higher than CK,the germination vigor,germination rate,fresh seedling weight,dry seedling weight,germination index and vigor index of two Medicago sativa varieties treated with 15mmol/L Ca2+ solution reached a higher level,and the resistance to acid stress of two Medicago sativa varieties treated with 5～15mmol/L Ca2+ solution was enhanced,and the resistance to acid of Victoria variety treated with Ca2+ solution was higher than Grandeur.The experiment results can provide reference for Medicago sativa cultivation under the acid environment in Guizhou and other regions in China.
