| Abstract: | The bacteriostatic efficacy of different concentrations of sodium benzoate and potassium sorbate in the process rapid propagation on virus-free potato plantlets were observed.The results showed that potassium sorbate being decanted in nutrient medium has obvious bacteriotatic effect and can significantly facilitate the growth of tube-seedling.The best effect is potassium sorbate of 20 mg/L. |
