对银杏５０个雌株品种和６个雄株类型叶片性状进行研究，结果表明，雌株或雄株品种或类型间叶片面积、厚度、单叶重及黄酮与银杏内酯含量存在显著或极显著的差异。证明了银杏品种或类型间叶片性状存在遗传变异，这种变异与雌雄株无关。初步提出了叶用银杏品种选育的项目和标准，并筛选出了泰山１号、泰山２号和泰山４号３个叶用银杏品种，既可直接推广应用于生产，亦可作为叶用银杏新品种育种的杂交亲本材料 The results showed that leaf area, thickness, single leaf weight and the content of flavonoids and ginkgolides in female or male varieties were significantly or extremely significant among 50 female and 6 male genotypes. The difference. It is proved that there are genetic variations in the leaf traits of Ginkgo biloba varieties or types, which has nothing to do with male and female plants. The project and standard of leaf gingko variety breeding were preliminarily put forward. Three varieties of Ginkgo biloba, Taishan 1, Taishan 2 and Taishan 4 were screened out, which can be directly used in production and also used as leaves with Ginkgo biloba Breeding new breed parental materials
