Abstract:

Effect of different PEG concentration and soaking seed temperature on activity and germination of seed was studied while Elacagnus mollis Diels seeds were the material. Results indicated under 25% PEG and 2℃, osmotic adjustment was good, and vigor index was increased significantly; germination rate was significantly increased compare to control group; seed quality was improve; plant resistance was strengthened. Analysis of physiological and biochemical indexes indicated that content of soluble protein and heat-stable protein and activity of SOD and CAT in seed increased under this condition. However, MDA content and POD activity decreased

Keywords:

Elacagnus mollis seed, low temperature stress, PEG, pretreatment
