摘　　要：通过对11个与银杏良种桂G86-1花期接近或相遇的雄株2年生长枝上的短枝间距、花芽率、每短枝上雄花数及雄花穗长、粗,出粉率等各项性状的分析,发现B号雄性单株的散粉期与桂G86-1花期基本相遇,且散粉期长,花芽率高,出粉量大,每单位长枝上雄花数多,是桂G86-1的最适宜授粉树。The result of analysis of length of internode, percentage of flowering buds, number of male flower per short shoot and length of anthotaxy etc on two-year-old shoots of 11 male trees showed that B have longtime of pollen dispersal, high flowering buds percentage, great volume of pollen, a large number of male flower of per meter long shoot and the florescence encounter with the Ginkgo biloba Cuhivars--‘Gui86-1＇. So, B is the optimum pollination tree.
