摘　　要：2011年从福建武平10棵红锥(Castanopsis hystrix)母株采集种子,测定种子性状,次年在浙江省淳安县繁殖实生苗,2013年定植,进行不同家系造林对比试验。结果表明,10个家系种子的千粒重、生活力和发芽率的平均变异系数均小于5%,发芽势的变异系数极大;1年生红锥苗造林存活率达100%,2015年时的保存率为89.33%,有3个家系的保存率达96.67%;10个家系在地径、苗高、分枝数都存在极显著差异。因此有必要在家系层面开展选择;家系选择中尤其要选择发芽势比较高的,同时要考虑造林的用途。Ten Castanopsis hystrix trees were selected for seed harvesting from Wuping of Fujian in 2011. Seed traits were determined and seedlingswere cultivated in Chun’an, Zhejaing province in the next year. In 2013, comparison tests were implemented on families by afforestation of 1-yearseedlings. The result demonstrated that thousand seed weight, viability and germination rate of tested seeds had mean variable coefficient less than5%, but germinative force had great variable coefficient. 1-year seedlings of different families had 100% survival rate, 89.33% conservation rate in2015, among them, seedings of 3 families had conservation rate of 96.67%. Ground diameter, seedling height and branching number of testedfamilies had great difference. Advices were offered for family selection by germinative force and afforestation target.
