Abstract:

The aims are to explore more sugar beet seed initiators to promote the germination, test the triggering effect of malic acid on seeds of sugar beet, and provide a theoretical basis for seed processing. We used TD701, TD703 and TD801 sugar beet seeds as the experimental materials and set five concentrations (1, 2, 5, 10 and 15 mmol/L), and a total of 15 experimental treatments. Then, we calculated the germination potential, the germination rate, the germination index and the vigour index. The test results showed that the 1 mmol/L malic acid improved the germination rate (67.67%), the germination potential (65%), the vigour index (199.84) for TD701 sugar beet seeds. 2 mmol/L malic acid improved the germination index (25.51) for TD701 sugar beet seeds. 1 mmol/L malic acid had the best triggering effect on TD801 sugar beet seeds, and the germination potential was 93.67%, the germination rate was 95.33%, the germination index was 39.53, and the vigour index was 316.88. However, different concentrations of malic acid had no effect on the germination of TD703 sugar beet seeds. As a result, different concentrations of malic acid have different effects on different kinds of sugar beet seeds, and the concentrations of proper triggering effect are also different.

Key words: organic acids, malic acid, sugar beet, seed vigour, difference comparison
