以银杏８个优良单株为材料，对种子形态品质进行了研究．通过相关分析确定反映银杏种实形态品质重要的定量指标为：果形系数、核形系数、仁形系数、单果重、单核重、单仁重、出核率和出仁率．对定量指标进行方差分析．并根据多重比较（Ｑ检验）结果排列名次．从而确定种子的优劣．该方法可靠性达９５％～９９％。 Eight excellent individuals of Ginkgo biloba were used as materials to study the morphological characteristics of seeds. According to the correlation analysis, the quantitative indexes that reflect the morphological quality of Ginkgo biloba are: shape factor, shape factor, shape factor, weight of single fruit, weight of single seed, single kernel weight, kernel rate and kernel rate. The quantitative analysis of variance. The rankings are ranked according to multiple comparison (Q test) results. To determine the pros and cons of the seeds. The reliability of the method reaches 95% ~ 99%.
