| Abstract: | In this paper,the determination of flavone (Quercetin,Kaempferol and Isorhametin),lactone (Ginkgolides and Bilobalide) contents in leaves collected from two year old seedling of 28 open pollinated families grown in 7 origins and 30 individuals within three families which came from the whole native range of Ginkgo biloba was carried out.These results showed that the differences of all the flavone and lactone compounds exhibited both among origins (populations),among families within a origin(population),more over,the differences among genotypes within a families appeared more significant than those among families within location.Negative relationship between flavones content and lactones content was observed,which was not at significant level.The concents both Ginkgolides and Bilobalide in leaves collected from two year old trees was similar to 16 year old trees.All information obtained in this study provided basis for genetic improvement strategy of Ginkgo biloba and intensive management of plantation for medicinal production. |
