电场处理油葵种子对幼苗期生长的影响

Influence of the Electric Field Treatment of Oil sunflower Seed on the Growth of Seedling

油葵种子经不同电场强度处理一定时间 ,实验结果表明 ,电场对种子萌发及幼苗生长均有一定的影响 .与对照相比 ,电场作用后 ,油葵种子发芽率提高为 1 .2 %～ 1 0 .8% ,根体积增长率为 2 1 .3%～ 1 50 .96% ,苗长的增长率为 0 .4 8%～ 2 3.3% ,水势提高率为 7.51 %～ 37.51 % ,束缚水提高率为 5.2 0 %～ 35.58% .

Oil sunflower seeds were treated in different electric field strength.The results are as follows,electric field influenced the germination of seeds and growth of seeding.Bomparison with check sample,the rate of germination of Oil sunflower seeds increased by 1.2%~10.8%,the rate of seed volume by 21.3%~150.96%,the rate of growth of seeding by 0.48%~23.30%,the rate of water potential and bound water by 7.51%~37.51% and 5.20%~35.58% respectively.
