摘　　要：从资源选择和生物学特性两方面对果用型三叶木通[Akebia trifoliata(Thunb.)Koidz.]的研究成果进行了总结。种源选择方面,在选择三叶木通(Akebia trifoliate)和白木通(Akebia trifoliata subsp.Australis)优质种源的基础上,再从丰产、品质、抗逆等方面遴选优株,提高可食率和实现无子化是育种的重点。生物学特性方面,从物候期、茎藤生长、花芽分化、开花和果实发育4个方面进行了归纳。The research results of Akebia trifoliata(Thunb.)Koidz.were summarized from resource selection and biological characteristics.In terms of provenance selection,on the basis of selecting high-quality provenances of A.trifoliate and A.trifoliata subsp.Australis,selecting superior plants from high yield,quality and stress resistance,improving edible rate and realizing seedless are the key points of breeding.In terms of biological characteristics,four aspects were summarized,including phenology,stem and vine growth,flower bud differentiation,flowering and fruit development.
