摘  要：
大量调查表明,中国的枇杷属植物极为丰富。现已发现有14个种和1个新类型─—大渡河枇杷。根据花期的不同和老叶叶背有无绒毛将它们分成4组。通过比较大渡河枇杷、栎叶枇杷和普通枇杷的形态、花粉特征以及茎皮、根过氧化物酶同工酶后认为,大渡河枇杷是一新变种,Eriobotrya prinoides Rehd.＆ Wils.var.daduheensis H.Z.Zhang.。形态上,最接近于普通枇杷,可能是普通枇杷的始祖之一。本文在结合分析植物群落、地理、气侯条件及普通枇杷的生物学特性和野生分布后认为,贡嘎山东南坡的大渡河中下游地区可能是普通枇杷的起源中心。

摘  要：
A recent investigation shows that China is rich in the germplasm resources of the genus Eriobotrya. 14 species and 1 new variety have been recorded. According to the season of flowering and the amount of * hairs on the lower surface of the mature leaf, these species can be classified into 4 groups.The Daduhe loquat differs from E. japonica and E. prinoides in morphology, size and shape of pollens, and peroxidase isozyme patterns. It can be considered as a new variety. E. prinoides Rehd. & Wils. var. daduheensis H.Z.Zhang. The Daduhe loquat may be one of the ancestors of E. japonica. A great number of wild plants of E. japonica and its relatives are distributed in the middle-and-lower reaches of the Daduhe River which is located to the south-eastern slopes of mountain. Gongga in western Sichuan. The climate, geologic structure and flora in this region arc quite complicated. This region may be considered as the originating place of E. japonica
