摘　　要：通过对浙西南野生小叶蚊母植株及其无性繁殖苗木的性状观测,结果表明:小叶蚊母个体形态存在明显差异,主要表现在花色、嫩叶叶色、叶形、树体结构和枝条特性、抗寒性、抗病性、开花结果习性等方面。花色可分为2个色系3种颜色;嫩叶叶色可分为2个色系4种颜色;叶片形状可分为3种类型,叶片大小可分为2种类型;树体结构和枝条特性可分为2种类型。可将浙西南小叶蚊母划分为12个园艺类型,其中LHWM01、LHWM02、LHWM04、LHWM05、LHWM11、LHWM12等6个类型具有枝叶密集,树冠紧凑,适应性强,观赏效果好等特点,被选为优良园艺类型,可在今后小叶蚊母产业化生产中直接推广应用,也可作为小叶蚊母新品种培育的优质育种材料。Through the traits observation of wild Distylium buxifolium and its asexual reproduction seedling in southwest Zhejiang,this paper found there were significant differences between the individual patterns of Distylium buxifolium, including blossom color,leaf color,leaf shape,tree structure,branch feature, cold resistance,disease resistance and flowering habit.It could be divided into 2 series and 3 colors according to the different blossom colors,2 series and 4 colors according to the different leaf colors,3 types according to the leaf shape,2 types according to the leaf size,2 types according to the tree structure and branch feature.Distylium buxifolium in southwest Zhejiang could be classified into 12 gardening types,and 6 of them including LHWM01,LHWM02,LHWM04,LHWM05,LHWM11 and LHWM12 should be selected as superior gardening types as they had dense foliage,more compact canopy,good adaptability and ornamental value.Thus,these 6 types could be promoted to use directly in industrial production in the future,and also could be served as new variety to cultivate superior breeding material.
