三种贝母核型的比较研究

The present paper deals with a comparative karyotypic study of three species in Fri- tillaria-F. thuncergii Miq., F. anhuiensis S.  . Chen et S. F. Yin and F. hupehensis Hsiao et K. C. Hsia.  The karyotype of F. anhuiensis S. C. Chen et S. F. Yin is first reported.       The karyotypes of the three species of Fritillaria are rather similar, all with K(2n)=24= 2m+2sm+12t+4st+4m (SAT), showing a close interspecific relationship.  They all have two pairs of st chromosomes, one of which is the third chromosome in all the three species studied, but the other is the seventh in F. thunbergii Miq, the eighth in F. anhuiensis S. C. Chen et S. F. Yin, and the fifth in F. hupehensis Hsiao et K. C. Hsia.  It tells us that there are some differences in their karyotypes.  All of the three species possess two pairs of satellite chromosomes with the satellites located on the long arms. A heterochromatic zone is found sometimes on long arms of No. IX chromosome in each species of Fritillaria and on one of No. I chromosomes in both F. thun- bergii Miq. and F. anhuiensis S. C. Chen et S. F. Yin, a chromosome polymorphism occurring between populations of Fritillaria. In addition, three B chromosomes are always found in most root-tip cells of F. hupehensis Hsiao et K. C. Hsiao.     

贝母属三个分类群的核型研究

本文对浙贝Fritillaria thunbergii Miq．(取材于浙江鄞县和舟山)、东贝 F.thunbergii var． chekiangensis Hsiao et K.C.Hsia和皖贝F.anhuiensis S．C.Chen et S．F.Yin的核型进行了分析比较， 其中东贝和浙贝(舟山)为首次报道．浙贝的核型：取材于浙江鄞县的为2n=24=4m(1sc) l)+4st(1sc) +16t(1sc)，取材于浙江舟山为  2n=24=2m+2sm+12st(1sc)+8t(2sc)，东贝的核型为 2n＝24=2m+2sm+8st(2sc)+12t(4sc)，皖贝的核型为2n=24=2m+2sm+8st(2sc)+12t(5sc)。3个分类群均属3B核型。
