摘要 通过野外调查和查阅大量标本、文献,对江西猕猴桃属植物的分布和区系特征进行了系统研究。江西省境内分布有猕猴桃属植物20种和11变种(或变型),其中葛枣猕猴桃(Actinidiapolygama(Sieb.etZucc.)Maxim.)、灰毛猕猴桃(A.cinerascensC.F.Liang)、楔叶猕猴桃(A.fasciculoidesvar.cuneataC.F.Liang)和簇花猕猴桃(A.fasciculoidesC.F.Liang)为江西新分布。江西猕猴桃属植物区系特征表现在:(1)种类丰富;(2)特有现象较明显;(3)多型性突出;(4)地理成分复杂,以中国特有分布式样为主;(5)种间、种内分化较强烈;(6)与邻近地区猕猴桃属植物的关系密切。还对江西猕猴桃属植物的分布与自然生境的关系进行了探讨。 The geographical distribution and floristic characters of Actinidia species from Jiangxi Province were studied by means of field surveys and examining herbarium specimen and literatures. The results indicates that there are 20 species, 11 varieties(or forms) of Actinidia distributed in Jiangxi Province, among which A. polygama (Sieb.et Zucc.)Maxim., A. cinerascens C.F.Liang, A. fasciculoides var. cuneata C.F.Liang, A. fasciculoides C.F.Liang are new records to Jiangxi Province. The area is rich in endemic species of the genus, 28 species (including varieties)endemic to China are found. Interspecific and intraspecific differentiation of Actinidia is significantly high. The geographical impact on the species is complex. The species endemic to China are widely distributed in the province. Flora of Actinidia in Jiangxi is closely related to the bordering regions of Fujian,Zhejiang,Hunan and Guangdong Provinces. The relationship between the pattern of Actindia in Jiangxi and their habitats is also discussed.
