Abstract
Membership function of fuzzy mathematic was used to evaluate the salt tolerance of fall nondormancy standard varieties of alfalfa(Dona Aan,Pierce,CUF101) at the germination period by considering germination power,germination percentage,root length,shoot length,the germination index and the vigor index as the evaluation indicators.This study indicated that low levels of salinity(0-50 mmol/L NaCl) did not increase seed germination.The increase of NaCl concentration reduced the germination power,germination percentage,root length,shoot length,the germination index and the vigor index when NaCl concentration was over 50 mmol/L.The effect of salt stress on the vigor index was stronger than that on the seed germination rate.Evaluation results of membership function of fuzzy mathematic showed that the salt tolerance of alfalfa varieties was Dona AanPiercCUF101Zhongmu No.1.
