摘要：

本文报告了我国现有栽种的三种来源的聚合草细胞学鉴定结果。结果发现

它们的染色体数目均为2n＝40。从染色体数目看，初步认为我国目前栽种的

三种来源不同的聚合草(朝鲜聚合草、日本聚合草和澳大利亚聚合草)是属于同

一个种，相当于聚合草属的外来聚合草(Symphytum peregrinum Ledeb．)。

Abstract:

The present paper reports the results of cytological studies of three samples of

comfrey introduced into China as forage plants. It is found that the chromosome nu-

mbers of these three different samples of comfrey are the same, 2n = 40. This number

is consistant with that of the Symphytum peregrinum Ledeb. in literature, but different

from that of the other species. Therefore from the view point of chromosome number

we consider preliminarily that these three samples of comfrey are identical with

Symphytum peregrinum Ledeb.
