Abstract:

The aims of this study was to apply the method of silica gel drying to the ultra-dry treatment of common beans, and analyze the main physiological activity related indexes, in order to provide scientific basis and practical reference for the long-term storage of beans seeds. After ultra-dry treatment, indicators such as protein content and dehydrogenase (ADH) content were measured using Coomassie Brilliant Blue G-250 staining, TTC method, thiobarbituric acid (TBA) method, etc. The results showed that when the water content of ‘Jiangjun’ was 6.95%, the seed vitality and physiological indicators were higher than that of the control, while the activity of antioxidant enzymes was significantly lower than that of the control. When the water content of ‘Ziguan’ was 6.89%, the physiological indexes were higher than that of the control, and the content of O2- decreased. When the water content of ‘Renaya’ was 6.15%, the germination rate was the highest, the protein content and ADH activity increased significantly, and the content of O2- and the MDA were not significant. These results indicated that moderate ultra-dry treatment had a greater effect on ‘Jiangjun’ seeds, and little or no effect on ‘Ziguan’ and ‘Renaya’ seeds. The results showed that the ultra-dry treatment was feasible for the preservation of common bean seeds, which laid the foundation for the long-term storage of common bean seeds.
