Abstract
After the seeds of 3 soybean varieties,Heizhenzhu,Jindou 19,Jinda 74 were artificially aged under the air tight condition of high temperature((48±1)℃)and high humidity(100% relative humidity),then primed by 10%,20% and 30%PEG-6000,variation of membrane permeability and the activities of protection enzymes were tested.The results showed that relative electrical conductivity of treated seeds decreased and then increased at first and subsequently decreased and rose again with extension of aging time;MDA content decreased continuously.POD activity declined at first slowly,then increased,finally declined rapidly;SOD activity rose slowly at first and then rapidly declined.After seeds aged of 3 soybean varieties were primed with different concentration PEG-6000,the membrane permeability and MDA conent reduced relatively,and the activities of protection enzymes raised.It suggested that seed resistance to abiotic stress was enhanced.In particular,after the seeds with aging slightly were primed by 20% and 30% PEG-6000,abilities of resistance to aging were significantly enhanced.
