摘　　要：为了探讨"早生黄金"梨的授粉特性,为其栽培与推广提供技术支撑,采用田间观察和授粉试验等方法对"早生黄金"梨的授粉特性进行了系统的观察与研究。结果表明:"早生黄金"梨在湖南省及其周边省地的开花期为4月初,花粉量为3080粒/花药,花粉活力为84.2%,花粉萌发率为77.6%,但自花授粉不结实,黄花梨、丰水梨是其最佳授粉品种,在生产上"早生黄金梨"和授粉树(黄花梨或丰水梨)的配置比例以5∶1为好。In order to provide technical support for cultivation and promotion of ＂Josengwhangkeum＂, its pollination characteristics were observed and studied. The result indicated that florescence of ＂Josengwhangkeum＂ pear in Hunan or neighboring province was early April, pollen amount was 3 080 per anther, pollen vigor was 84.2%, germination rate was 77.6%. But self--pollination is not solid, Huanghua and Fengshui are the best pollination varieties, proper ratio of ＂Josengwhangkeum＂ and pollination tree should be 5 ： 1.
