Abstract

Abstract:

Fritillary is a precious Chinese medicinal herb. Those native to Xinjiang

Northwest China, are even more distinguished from other sources for their purity and

effectiveness. Fritillaria in Xinjiang comprises 8 native species and one (F. thunbergii

Miq.) introduced from Zhejiang, East China. In this paper the authors describe the

karyotypes of 6 species native to Xinjiang and F. thunbergii Miq., of which five, i.e.F.

olgae Vved., F. walujewii Regel, F. yuminensis X. Z. Duan, F. karelinii (Fisch.) Baker

and F. thunbergii Miq. were studied for the first time. Detail observation and measur-

ment of chromosomes in each of them were made. The data obtained may be summa-

rized as follows:

scietific name karyotype formula (2n=)

F. pallidiflora Schrenk 2m + 2sm + 6st + 14t

F. olgae Vved. 4m + 6st + 14t

F. walujewii Regel 2m + 2sm + 8st+ 12t

F. yuminensis X. Z. Duan 4m + 8st + 12t

F. verticillata Willd 4m + 8st + 12t

F. karelinii (Fisch.) Baker 4m + 4sm + 4st + 12t

F. thunbergii Miq. 2m + 2sm + 4st + 16t

The karyotype of the native species are, on the whole, similar to each other except

that of F. karelinii (Fisch.) Baker, a species inhabiting desert areas. The number of

m-sm chromosomes has increased from 2 to 4 and the number of st-t chromosomes

decreased correspondently. So is the karyotype of F. thunbergii Miq. which is noted

for its high ratio of long chromosome/short chromosome and the more t-chromosomes.

These two peculiar karyotypes coincide amazingly with their specific natural habitats.
