| Abstract: | Having investigated all sorts of Ginkgo biloba in Shongxian county, by primary election,Subsequent election and high grafting contrast test, two sorts of Ginkgo biloba superior clone have been chosen.They are not only high medical quality but also outcome early,high and stable yield.They are named black Ⅰ and Ⅱ Ginkgo biloba. Progesterone content in seed kernel and leaves of black Ginkgo biloba is 0 9mg/kg and 8 5g/kg. Progesterone content in seed kernel and leaves of black Ginkgo biloba is more 50% and 41 7% than that of contrast.The aritle also introcluces superior economic character,form characteristic and bioecology property of black Ginkgo biloba. |
