Abstract:
Abstract:Taking Chimonanthus praecox (L.) Link seed as material,the water permeability of seed coat was studied after acid etched 30 minutes,the distribution of germination inhibitors were studied by the effect of extracted germination inhibitors on Arabidopsis’ seed germination,and the effect of GA3 on the seed germination using the wintersweet seeds treated by dense sulfuric acid were researched.The results showed that seed coat had a poor water permeability and hindered water absorption seriously,and seed extracting solutions mainly in kernel inhibited the germination of Arabidopsis’ seeds.The treatment of 125 mg/L to 500 mg/L GA3 could break the physiological dormancy and improved the germination rate and germination performance of the wintersweet seeds.The effective of soaking in 250 mg/L GA3 for 6 hours was the best,and the time of germination was 3 days earlier than the control and the germination rate and germination energy reached 95.8%,41.7% respectively，and 25.23%,91.60% higher than that of the control respectively.
