Abstract

Abstract:

The aims are to explore initiators that are more conducive to promoting the initiation of sugar beet seeds, and measure the initiation effect of vitamin C on beet seeds, providing relevant basis for the selection of beet seed coating materials. This experiment used TD801 and TD802 sugar beet seeds as experimental materials, and designed three different concentration gradients (50, 100, 200mg/L) and three different time treatments (8, 16, and 24 hours). The germination potential, germination rate, vitality index, germination index, and conductivity of the treated beet seeds were analyzed and compared. The results showed that VC solution under different treatments had a promoting effect on the germination of sugar beet seeds. Among them, the 300 mg/L VC treatment had a significant improvement effect on TD801 seeds after 24 hours, the bud potential was 90.67%, the germination rate was 92.67%, the germination index was 40.36, and the vitality index was 514.60. At this time, the seed priming effect was the best. The VC concentration that had the greatest impact on TD802 sugar beet seeds was 100 mg/L, and the treatment time was 16 h. It indicated that when the same initiator was used to treat different sugar beet materials, the optimal concentration for initiation was different.

Key words: sugar beet, seed, initiator, vitamin C, seed initiation, initiation effect, concentration gradient, time treatment, seed coating agent
