Abstract: "The influences of microwave radiation pretreatment of seeds of Isatis indigotica with different times on the germination rates of seeds, activities of amylase and proteinase in cotyledon and development of seedling were investigated. The germination rates of seeds treated with different times of microwave radiation were 3.9%-14% higher than that of the control group. The activities of amylase in cotyledon in the exptl. groups were 23%-90.5% higher than that of the control group, and those of the total amylase were 25%-90.8% higher than that of the control group. The activities of proteinase in the exptl. groups were 2.6%-19% higher than that of the control group. The areas of seeding in the exptl. groups were also significantly higher than those of the control group (P < 0.05). The results showed that the germination of seeds and development of seeding of I. indigotica could be improved by low-dose microwave radiation.

Abstract: “The effects of microwave radiation of Isatis indigotica with different time length on germination ratio, activity of amylase, activity of ALT, activity of AST, activity of proteases, concn. of sol. protein, free amino acid concn., DNA concn., cotyledon area and biophoton emission were studied using the seeds being irradiated with microwave after soaked for 3 h. The results showed that microwave radiation treatments with different time length could improve the germination ratio, activity of amylase, activity of ALT, activity of AST, activity of proteases, concn. of sol. protein, free amino acid concn., DNA concn., cotyledon area and biophoton emission. And the microwave radiation of low doses could stimulate the seeds germination and improve the cotyledon development. The effect of 8 s pretreatment of microwave therein mentioned was the best for Isatis indigotica fort.”
