Environmental and genetic factors were studied by field experiments and pot experiments. Content of flavonoid and terpene content in leaves of Ginkgo biloba (L.) Siberian, half-Siberian families, and clones were tested in lab, and the results are as follows:
Soil moisture affects the content of flavonid and terpene in G. biloba leaves. Drought stress favors for the accumulation of falvonid and terpene. Wet soil and flooded conditions has no advantages to improve the contents of flavonid and terpe...
