Physiological and ecological responses of alfalfa and milkvetch seed to PEG priming
PEG引发紫花苜蓿和沙打旺种子的生理生态效应

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% ...
