Effects of Sodium Metabisulfite on Seed Priming in Sugar Beet
摘要
Abstract
[Objective]It provides a theoretical basis for selecting a better initiator in production practice.[Methods]In this study,sugar beet seeds of'TD801'were treated by 6 concentrations of sodium metabisulfite(10,20,50,100,200 and 300 mg/L)and two time gradients(18 h and 24 h),and the effects of different concentrations of initiation treatment on the germination of sugar beet seeds was determined.[Results]Compared with the control,the germination potential and germination rate of sugar beet seeds in all treatments were not significantly improved,and the inhibition effect of treatment with 300 mg/L for 18 h was the most obvious,and the germination potential and germination rate declined by 10.00 and 11.33 percentage points,respectively.From the germination index and vitality index,the overall effect of sodium metabisulfite with different concentrations for 24 h was better than that for 18 h,and the combination of 50 mg/L for 24 h performed the best,with the increase by 52.44%and 76.19%for its germination index and vitality index,respectively.The relative conductivity of the treatment was lower than the control,performed a decrease of 222.00-234.60 percentage points.[Conclusion]The results showed that different concentrations of sodium metabisulfite could improve the vigor of beet seeds and promote the germination of beet seeds,and the germination effect varied with treatment time and concentration.Overall,the treatment of 50 mg/L for 24 h performed better.关键词
