摘 要 ：在扫描电镜下观察了我国广西原产的10种和3变种金花茶的花粉形态。其花粉外壁纹饰可分为三个类型。一、拟网纹饰:东兴金花茶、武鸣金花茶、(坛洛)金花茶、小果金花茶和陇瑞(玫瑰)金花茶。二、穴状纹饰:毛籽金花荼、(防城)金花茶和毛瓣金花茶。三、突起纹饰:小花金花茶、显脉金花茶,大样(?)岗金花茶、平果金花茶和山墟金花茶。在各个种及变种之间,花粉形态也存在一定的差异。

Abstract:Pollen morphology of 10 species and 3 varieties of yellow camellias from Guangxi has been examined under SEM.Three basic sculpes were defined. (1)viz., ornate(C.chrysantha,C.chrysantha var.microcarpa, C. tunghinensis, C.wumingensis, and C.sp.); (2)perforate(C.ptilosperma, C.chrysantha var.,and C.pubipetala), and (3)rugulate (C. euphlebia, C. microantha, C.pingguoensis, C.longgangensis, and C.sp.) Morphological divergence occurs between all species and varieties observed in respect to pollen characterictics.
