1、庆元县红花油茶种质资源树体和果实性状变异分析摘要：为研究庆元县红花油茶(CamelliachekiangoleosaHu)种质资源树体性状和果实性状变异，对其9个自然分布地点进行调查分析。结果表明，红花油茶种质资源总体单株间树体性状变异大小顺序为枝下高、冠幅长、冠幅宽、树高、地径、叶长、叶宽、叶形指数，果实性状变异大小顺序为结果量、单果重、单果鲜子总量、单个鲜子重、鲜子率、单果子数、干子率，果实性状在分布区间均表现出极显著差异；由聚类分析结果得出，景区管护站和茶木淤林场、半坑村和小际头村、杨家庄村和车根村的树体性状分别归为一类，三堆村和岗背林场的果实性状归为一类；由相关分析
2、结果得出，树体性状之间相关性大，单果重和果径呈极显著正相关，与鲜子率呈极显著负相关。综合而言，茶木淤林场、三堆村、岗背林场和小际头村这4个点的果实经济性状相对较高，可作为重点选优群体。关键词:红花油茶(CamelliachekiangoleosaHu)；树体性状；果实性状；变异；庆元县分类号：S794.4+3(554QY)文献标识码：A文章编号:0439-8114(2016)12-3097-05D0I：10.14088/j.cnki.issn0439-8114.2016.12.025Abstract：Tostudythetreeandfruitcharactervariat
