摘要: 本文根据15省30余个县的实地考察,和对采自25省的66份中国龙葵种籽进行种植观察,并与国外的有关研究资料对比分析,在国内首次提出;(1)中国龙葵复合种的四个种,从低纬度到高纬度(18.6-53.5°N),分别属于二倍体,四倍体和六倍体种;(2)从中国南方到北方,自然形成了二倍体,六倍体与二倍体交叉,六倍体与四倍体交叉三个地理分布区。

关键词: 龙葵复合种, 二倍体, 四倍体, 六倍体, 地理分布

Abstract: On the basis of the field inspection in 30 counties of 15 provinces and the observation on plant of collectable 66 seeds share of Chinese s. nigrum complex from 25 provinces, as well as analysis and comparesion of the oversea relative research materials, we put forard domestically the following:(1) From low latitudes to high latitudes (18.6-53.5°N) the four species of Chinese s. nigrum complex respectively belong to diloid, tetraloid, hexaloid;(2) From the southern China to Northern China, natrually form three geographical distributive areas of diloid, the intersect of hexaloid and diloid, as well as the intersect of hexaloid and tetraloid.

Key words: solanum nigrum complex, Diloid, Tetraloid, Hexalaid, Geographic distribution
