摘　　要：叶片萜内酯含量是药用银杏Ginkgo biloba的关键品质属性及重要指标。于2016年9月,对陕西宝鸡银杏种质资源圃引进和筛选的20个银杏优良无性系叶片进行了萜内酯含量的差异性研究。结果表明,银杏叶质量、叶面积、叶长、株叶数、树高和叶含水率是影响其叶片萜内酯含量的主要因子;筛选出生长性状、叶萜内酯总量具有优势的3个优系:C94-16,C95-09和C94-56。Experiment were conducted in September 2016 on difference of terpene lactones content in leaves of 20 introduced and selected clones of Ginkgo biloba, which were 7-years grafted on 15-18 year rootstocks in Baoji Ginkgo Germplasm Resources Garden, Shaanxi province. The results showed that leaf weight, leaf area, leaf length, leaf number on one tree, tree height and leaf water content were the main factors affecting terpene lactones content. Three clones were selected with better growth traits and total terpene lactones content.
