Abstract:

To study the effect of different concentrations of tartaric acid on germination of sugar beet seeds and to provide a basis for screening sugar beet seed coating, a total of nine sets of treatments were carried out and indexes were measured using three different concentration gradients of tartaric acid at 5, 7.5 and 10 mmol/L and three gradients of time at 8, 16 and 24 h. Sugar beet crop seed 'TD801' was used as the test material. Compared to the control CK, the germination potential of the treatments increased by a minimum of 0.83 percentage points and a maximum of 6.67 percentage points; germination increased by a minimum of 0.66 percentage points and a maximum of 9.67 percentage points; germination index increased by a minimum of 15.39% and a maximum of 31.71%; the vigor index increased by a minimum of 30.09% and a maximum of 82.83%; relative conductivity was reduced in all cases compared to control CK, with a minimum decrease of 68.96 percentage points and a maximum decrease of 100.93 percentage points. When the concentration was 10 mmol/L for 16 h, the effect on germination potential and germination rate was better. When the concentration was 7.5 mmol/L for 16 h, the effect on germination index and vigor index was better; a concentration of 7.5 mmol/L for 24 h was more effective on relative conductivity. All nine treatments promoted seed initiation of sugar beet, and tartaric acid solutions at concentrations of 7.5 mmol/L and 10 mmol/L for 16 h were more effective in seed germination of sugar beet.
