%X Poor seedling emergence is one of the critical problems in grassland production in China.Osmotic polyethylene glycol (PEG 6000) priming technique (-0.6MPa, 24h) was used to study priming effects on seed germination and their physiological and ecological responses in different quality commercial seed lots of alfalfa (Medicago sativa) and milkvetch (Astragalus adsurgens). Results showed that PEG priming significantly enhanced (p<0.05) early germination and germination index, and reduced time required for 30% ...
