Based on this result, molecular identification of clones ( cultivars) of Ginkgo biloba Linn. can be effectively performed by using haploidic seed endosperm or diploid foliage as experimental materials, providing a scientific foundation for the identification, protection and registration of Ginkgo improved varieties. 在此基础上,可利用单倍体种子胚乳或二倍体叶片等材料实现对银杏无性系品种的有效分子鉴别,为银杏的良种鉴别、保护和登录提供了科学依据。
