Effects on Germination of Sugar Beet Seeds:Different Concentrations of Erythritol
To assess the impact of varying erythritol levels on seed germination and to provide a foundation for selecting sugar beet seed coating,the seeds of sugar beet'TD801'were used as the test material in this study.The three concentration gradients(5,7.5,10 mmol/L)and three hour time gradients(8,16,and 24 h)were set up,and then 9 treatments were used to determined the indexes.The germination potential was increased by 4％-12.33％in comparison to the control CK;the rate of germination was raised by 9％-12％compared to the control CK;and the germination index was also augmented by 28.92％-60.74％compared with the control CK;the vitality index was increased by 69.45％-116.81％compared with the control CK;and the relative electrical conductivity was decreased by 58.26％-83.10％compared with the control CK.When the concentration was 5 mmol/L for 8 h,it had a better effect on improving germination potential;when the concentration was 5 mmol/L for 24 h,the effect of germination rate was better;when the concentration was 5 mmol/L for 16 h,it had a better effect on germination index and vitality index;when the concentration was 10 mmol/L for 24 h,it had a better effect on the relative electrical conductivity.The 9 treatments had the effect of promoting the initiation of sugar beet seeds,and a greater overall effect on seed germination of sugar beet was observed when the concentration of erythritol solution was 5 mmol/L for 16 hours.
