Abstract:
In recent years,research on the mutation breeding of soybean was comparatively active and successful,while soybean mutation induced by high pressure treatment of seeds has not been reported.In the present research,effects of high pressure stress of seed on the agronomic characters,yield and quality of soybean were studied.The soybean seeds,Kaijiao 8157,were separated randomly into two groups(each 100 seeds),one was pretreated by 20MPa high pressure nitrogen gas for 4 h at room temperature,and the other without treatment was regarded as control group.All seeds were planted under same natural conditions in Chengdu of Sichuan province.The growth characteristics of the plants such as germination ratio,growth period,plant height,stem diameter and seed yield were observed and compared,and four main nutrition components of the yielded seeds were also tested.It was shown that the average seed yield per plants in the treated group increased 30.6 percent in comparison to the control group and T-test indicated the difference is significant in the believable level of 99%.The changes of four nutrition components (unsaturated fatty acid,saturated fatty acid,fattiness and protein) in the treated group are inclined to the improvement of seed quality.Additionally,one plant in the treated group was obviously prolific in the seed yield,which increased 204.48% in comparison to the average yield of the treated group.These results suggest that high pressure treating seeds is a promising way to improve yield and quality of soybean.
