Alfalfa ( Medicago sativa L.) plays an important role in the development of animal husbandry karst region southwestern China, and environmental stress has a significant impact on germination alfalfa seeds. This study subjected seeds to calcium salt (0–100 mM), drought (0–0.53 MPa), pH (pH 3–9). Germination indicators (germination rate, potential, index, vigor index), seedling morphological (shoot length root length), biomass were measured assess seed resistance. The results showed that mild (5% PEG solution) weak alkaline 8) promoted germination, 20 mM CaCl 2 solution significantly increased rate. system seedlings was more sensitive three types stress. Under moderate (40 only slight decrease tissue water content observed. (10% PEG), fresh weight decreased, but dry increased. 9), both provides theoretical reference for selecting plants suitable cultivation environments.
