Abstract:

Abstract: Shape characters, nutrient contents and medicinal contents of seventeen clones of ginkgo biloba were investigated. Results indicated that: The nut length, nut width, nut thick, ratio of length to width and single nut weight of seventeen ginkgo clones were significantly different, there were significant correlation between single nut weight with nut length and nut thick, also highly significant correlation between single nut weight with nut width. The content of protein, content of soluble sugar, content of starch, content of lactones and content of flavonoids of seventeen ginkgo clones were significantly different, there were significant correlation between nut length with content of protein and single nut weight with content of starch. The seventeen ginkgo clones were classified as three groups based on shape characters, nutrient contents and medicinal contents of nut.
