But the testa have being regarded as the waste in further process of gingko seeds, as there has no appropriate way to use them.

银杏外种皮的提取物具有一定的杀虫杀菌活性很早就有报道，然而，一直以来在银杏的深加工产业中外种皮却苦于没有成熟的提取方法，而被当作垃圾丢弃，这不仅是一种资源浪费，更对周边环境造成了严重影响，随着银杏产业规模的不断扩大，这已成为许多种植基地政府和企业迫切要求解决的问题。

The gingko whole body is valuable, is honored as "the money tree", the fruit, the clothes, the leaf, the root, the material have the high development use value; Plans Jiangsu Province baiera forest park which constructs is the nature is unique, also not artificial restoration's possibility, the project has the potential economical value and gingko resources conservation urgent.

Ginkgo is an ancient and mysterious dioecian plant, living on the earth for more than 70 million years.

银杏是一种古老而神奇的树种，现存的银杏其历史可追溯到7000万年以前，它雌雄异株的特性，注定了雌雄银杏相依相伴的生活。

The average percentage of polymorphic bands are 72.06% for ISSR and 66.67% for RAPD respectively. The genetic diversity of ginkgo revealed by ISSR (the average effective number of alleles is 1.8780, the average Nei"s gene diversity is 0.4652, and the average Shannon"s information index is 0.6574) are all higher than those by RAPD (the average effective number of alleles is 1.7842, the average Nei"s gene diversity is 0.4317, and the average Shannon"s information index is 0.6211), while the standard errors of the parameters estimated by ISSR were lower. Therefore, ISSR molecular markers are more suited than RAPD molecular markers when testing the genetic diversity of ginkgo populations and determining the genetic relationship of among populations or among individuals which are much similar hereditarily.

本文应用RAPD和ISSR两种分子标记技术，选取中国5个可能的野生银杏居群共计75个样品，对其遗传多样性进行了研究，得出以下结论：(1)用筛选出的12个RAPD引物和10个ISSR引物进行PCR扩增，分别扩增出65条和68条重复性高、清晰的条带，多态性位点百分率分别66.67%和72.06%，ISSR揭示的银杏遗传多样性(平均有效等位基因数目为1.8780，平均基因多样度为0.4652，平均信息指数为0.6574)高于RAPD所得到的结果(平均有效等位基因数目为1.7842，平均基因多样度为0.4317，平均信息指数为0.6211)，其所估算参数的标准差要低于RAPD所估算出的值，因此，在研究亲缘关系非常近的银杏物种的遗传多样性并试图确定居群间或个体间的遗传关系时，ISSR分子标记技术比RAPD分子标记技术更为合适。

The populations of DH, TM and WC are the concentration places of wild Ginkgo biloba L.. Among these populations, there are a great numbers of seedlings, which have more strong renovative ability .Therefor, these are the best regions to protect the gentic diversity using combined with in situ and transferred and should establish conservation areas in these places.

湖北大洪山、浙江天目山、贵州务川是银杏古树的集中分布区，银杏居群内的种子实生苗较多，具有较强的种群自然更新能力，是银杏遗传多样性就地和迁地保护的最佳地区，应尽早建立自然保护区。
