1、慶元縣紅花油茶種質(zhì)資源樹體和果實性狀變異分析摘要：為研究慶元縣紅花油茶(CamelliachekiangoleosaHu)種質(zhì)資源樹體性狀和果實性狀變異，對其9個自然分布地點進行調(diào)查分析。結(jié)果表明，紅花油茶種質(zhì)資源總體單株間樹體性狀變異大小順序為枝下高、冠幅長、冠幅寬、樹高、地徑、葉長、葉寬、葉形指數(shù)，果實性狀變異大小順序為結(jié)果量、單果重、單果鮮子總量、單個鮮子重、鮮子率、單果子數(shù)、干子率，果實性狀在分布區(qū)間均表現(xiàn)出極顯著差異；由聚類分析結(jié)果得出，景區(qū)管護站和茶木淤林場、半坑村和小際頭村、楊家莊村和車根村的樹體性狀分別歸為一類，三堆村和崗背林場的果實性狀歸為一類；由相關(guān)分析
2、結(jié)果得出，樹體性狀之間相關(guān)性大，單果重和果徑呈極顯著正相關(guān)，與鮮子率呈極顯著負(fù)相關(guān)。綜合而言，茶木淤林場、三堆村、崗背林場和小際頭村這4個點的果實經(jīng)濟性狀相對較高，可作為重點選優(yōu)群體。關(guān)鍵詞:紅花油茶(CamelliachekiangoleosaHu)；樹體性狀；果實性狀；變異；慶元縣分類號：S794.4+3(554QY)文獻標(biāo)識碼：A文章編號:0439-8114(2016)12-3097-05D0I：10.14088/j.cnki.issn0439-8114.2016.12.025Abstract：Tostudythetreeandfruitcharactervariat
