Abstract:
Taking two-year old Ginkgo seedling ‘Jiafoshou’ as the material，the ginkgo seedlings were sprayed with methods of different concentrations biological nano-selenium，the experiment studied the effects of different concentrations of bio-nano-selenium treatment on the physiological indexes and flavonoid content of ginkgo leaves at different growth stages，which hoping to provide a reference for ginkgo cultivation and efficient use of bio-nano-selenium.The results showed that the contents of chlorophyll，soluble sugar and total flavonol glycosides in the G.biloba leaf with 1.6 mmol?L-1 biological nano-selenium treatment increased in July and September，which were 43.87%，59.92%，43.99% and 13.86%，18.60%，35.04% higher than control group，and the improvement was significantly different.Paying attention to the 1.6 mmol?L-1 nano-selenium treatment group，the total flavonol glycoside content in June，July，September and October were 6.78%,31.84%,36.70% and 9.78% higher than it in August，which were significant differences in July and September.In conclusion，it could obtain the best quality G.biloba leaf if 1.6 mmol?L-1 biological nano-selenium fertilizer was applied and leaf is collected in July and September.
