摘要/Abstract

摘要：

报道五种苏铁的染色体数目和核型，其中红河苏铁 (Cycas hongheensis)、叉孢苏铁 (C.segmentifida)和十万大山苏铁 (C.shiwandashanica) 为首次报道。

关键词: 苏铁, 染色体数目, 核型

Abstract:

In this work, the chromosome numbers and karyomorphology analyses were carried out on five species of Cycas L. from the south China. The data about C.hongheensis, C.segmentifida and C.shiwandashanica are reported for the first time. The chromosome counts of five species are 2n=2x=22.

Key words: Cycas, Chromosome numbers, Karyomorphology
