Abstract:
The vegetative characters of Ligusticum chuanxiong Hort. cv. Fuxiong
are described in comparison with L. chuanxiong Hort. and L. sinense Oliv. The chromosome
numbers and karyotypes of the three taxa were studied in root tip cells by Feulgen’s squash
method. Their karyotypes are determined as follows: L. chuanxiong, K(2n)=22=16 m+
4sm+2st (sat); L. chuanxiong cv. Fuxiong, K(2n)=33=24 m+6sm+3st (sat); L. sinen-
se, K(2n)=22=12 m+6sm+2sm (sat)+2st (sat).
The karyotypic similarities are found between L. chuanxiong and its cultivariety, but
the former is a diploid while the latter probably is a homologous triploid.
