摘要
对作孚连蕊茶(Camellia tsofui S.S.Chien)3个单株(分别采自重庆缙云山和浙江国际山茶物种园)的主要形态特征进行观测和比较,并采用Super-GBS技术进行SNP位点相似度分析。与原始文献描述相比,作孚连蕊茶在原生境和迁地栽培环境存在以下变异:生活型为灌木或小乔木,花顶生和腋生,花蕾白色或紫红色,花梗及萼片总长6~12 mm,游离花丝疏被毛或近无毛,柱头3裂,裂片长不足1 mm,或1~3 mm。此外,幼叶绿色或紫红色;蒴果近球形,横径5~13 mm,1室,种子1粒;种子近球形,深褐色。作孚连蕊茶3个单株两两之间的SNP位点相似度均在93%以上,为作孚连蕊茶的种内变异。
The major morphological characters of three individuals of Camellia tsofui S.S.Chien(collected from Jinyun Mountain of Chongqing and International Camellia Species Park of Zhejiang)were observed and compared,and similarity analysis on SNP sites was performed by using Super-GBS technology.Compared with the original literature description,C.tsofui in original habitat and ex situ cultivation environment has following variations:its life form is shrub or small tree,flowers are terminal and axillary,flower buds are white or purplish red,the total length of pedicel and calyx are 6-12 mm,free filaments are sparsely hairy or nearly glabrous,style trifid,and the length of lobes are less than 1 mm or 1-3 mm.In addition,its young leaves are green or purplish red;capsule subglobose,5-13 mm in transverse diameter,one room,and one seed;seed subglobose,and dark brown.The similarities of SNP sites between each two of three individuals of C.tsofui are all more than 93%,which are intraspecific variations of C.tsofui.
