摘　　要：[目的]进一步推广栽植厚皮香,为厚皮香种质资源的良种选育奠定基础。[方法]以筛选的20株厚皮香为研究对象,对各单株的生长、种子和果实性状、种子发芽率等进行分析。[结果]树高、地径、分枝数和花量间相关性显著。种子和果实的长度、宽度以及平均单果重5个表型性状,各单株间也存在差异。以7号单株的树高(247 cm)、地径(45.16 mm)、分枝数(17)、花量(426)、种子长度(7.91 mm)、种子宽度(6.66 mm)、果长度(15.19 mm)、果宽度(13.78 mm)和平均单果重(2.75 g)最大,且发芽率也为最高,达57%。[结论]7号单株可作为厚皮香优良单株。[Objective]To lay a foundation for further popularizing the planting of Ternstroemia gymnanthera,and also for the breeding of germplasm resources of Ternstroemia gymnanthera.[Method]The growth,seed and fruit characters,seed germination rate of 20 individuals were analyzed.[Result]There was significant correlation among tree height,ground diameter,branch number and flower quantity.The five phenotypic traits of seed and fruit,such as length,width and average fruit weight,were also different among individual plants.The tree height(247 cm),ground diameter(45.16 mm),branch number(17),flowering amount(426),seed length(7.91 mm),seed width(6.66 mm),fruit length(15.19 mm),fruit width(13.78 mm)and average fruit weight(2.75 g)of No.7 single plant were the highest.The germination rate was also the highest at 57%.[Conclusion]No.7 can be regarded as an excellent single plant of Ternstroemia gymnanthera.
