摘　　要：本文对贵州省惠水分布的清香木姜子进行了优良单株选择,从33株表型优良的单株中筛选出23株进行果实及含油率测定,平均树龄6a以上;分布类型主要为散生生长天然林,平均树高4.27m,平均冠幅8.84m,平均单株结实量276.48g,平均含油率3.72%。对采集的果实进行了各性状检测和分析,确定了优树选择指标,并初步选择出18株表型优良和含油率高的单株。The selection criteria for superior individuals of Litsea euosma W.W. Smith were set up based on an overall survey in Huishui county of Guizhou province, and 23 individuals were selected among 33 L. euosma trees with good surface features to analyze the oil content and other traits of their fruits.The mean age of these superior plants was 6 years old, and they were mainly scattered in natural forest.Their average height was 4.27m with average crown diameter of 8.84m.The average single tree fruit yield was 276.48g, and the mean oil content was 3.72%. A series of the fruit traits of the superior individuals were determined and analyzed, based on which 18 superior individuals were finally selected, all of which had obvious fine surface features and high oil content.
