Ancient Ginkgo biloba was selected as material to make fact-finding.The result showed that there were 442 ancient Ginkgo biloba trees in Jiangxi Province,which were distributed among 9 cities,45 countries and 63 villages and towns.Among of them,153 trees had growth indexes.In the 88 known sex of Ginkgo biloba,the fe-male plants accounted for 75. 00%.The maximum tree height was 40. 0 m,while the minimum was 7. 0 m.The maximum tree age was 2 900 years and the minimum was 100 years.The maximum DBH was 3. 57 m while the mini-mum was 0. 20 m.The maximum average crown was 31. 0 m while the minimum was 0. 55 m.There were 7 chichied ginkgo trees,and the maximum number of chichies was 10,and the largest chichi was 60 cm.There were 22 mult-trunked ginkgoes,of which the maximum number of mult-trunks was 15 per individual and the DBH of the biggest mult-trunk was 1. 15 m.There were also two-colored ginkgoes,different fruit ginkgo.There are two typical ancient ginkgo trees in Jiangxi Province.
