摘要
在巩留县以南的凯特明山东端的前山峡谷中分布看一片野核桃（Juglansregia）林，它是新疆伊犁野果林的主要组成树种，是珍贵的山地“残遗”群落。新疆野核桃与栽培核桃在形态上及品质上极其相似，它是栽培核桃的直系祖先，由于长期的实生繁殖，它有许多变异类型。作者于1985－1989年参加了《伊犁野果林的综合研究》课题，对几种野生果树进行了定点观察记载，对野核桃的植物学特征，生物学特性、生境、经济性状、抗寒性、抗病性等方面作了重点调查，并作了种下分类。本文简述了野核桃十四个类型的主要形态特征，生长结果习性，经济性状等，其中有一些薄壳型、丰产型及抗寒抗病等类型，有的品质极佳，可供研究和利用者参考。
A tract of the wild walnuts trees(Tuglans regia)which is distributed in the east of the Ketmin Mountains in the southern Gongliu County. It is a main component trees species of Xinjiang Ili wild fruit trees forests. The present forest is a valuable “relict”in the mountain region.Xinjiang wild walnuts(Juglans regia L. )are very similar to cultural walnuts species in the shape and quality,it is direct family ancestors of the cultural walnuts. Because of the long propagate the mselves by seeds,there are many variant types. Writers jioned in the 1985 to 1989《a synthetical study of Xinjiang Ili wild fruit-trees forest》problem. While general investigation,we made a located observation on the major several species of the wild fruittrees. We made a focal points investigation to botany characteristic,biological characteristic,distribution,ecological environment, habitat and economic character etc. of them,and made a classification of subspecies. The article introduced altogather Xinjiang wild walnut. (Juglans regia L.)of the 14 types.
