中文摘要	对4种锦鸡儿属(Caragana Fabr)植物的核型进行了分析,得出4种染色体核型:秦晋锦鸡儿(C.purdomii Rehd.)染色体数为2n=16, 其核型公式为2n=16=16 m(4 SAT);小叶锦鸡儿(C.microphylla Lam.)染色体数为2n=16,其核型公式为2n=16=14 m(2 SAT)+2 M;中间锦鸡儿(C.intermedia Kuang et H.C.Fu)染色体数为2n=18,其核型公式为2n=18=16 m(4 SAT)+2 M;树锦鸡儿(C.arborescens Lam.)染色体数为2n=20,其核型公式为2n=20=20 m (4 SAT).由此可推测:中间锦鸡儿可能为小叶锦鸡儿和树锦鸡儿或秦晋锦鸡儿和树锦鸡儿的中间类型或杂交种,也可能是具有递增染色体基数的不同种
英文摘要	Peashrub is popular name of Caragana Fabr. and up to now there are about 67 species of Peashrub were recorded in China, which are mainly distributed in arid and semiarid areas of North China. All species of peashrub developed typical biological features, which are highly drought-tolerant and good shrubs for dune-fixation, animal feeding, and biological resources for fuel energy and fiber material. They are valuable plants in eco-environment construction of North China. It is very important to analyze the karyotypes of Caragana Fabr. and reveal their genetic diversities for further protecting their idioplasmatic resources and utilizing for human. The Karyotypes of four species in Caragana were analyzed in this paper. Present results indicated that four species had different chromosome number and karyotypes. The number of chromosome was 16,16,18 and 20 in C. purdomi Rehd., C microphylla Lam., C. intermedia Kuang et H. C. Fu and C. arborescens Lam.; While their karyotypes were 2n = 16 = 16 m (4 SAT),2n = 16 = 14 m (2 SAT) +2M, 2n = 18 = 16 m (4 SAT) +2 M and In =20 =20 m (4 SAT). It can be inferred that the C. intermedia Kuang et H. C. Fu may be the hybrid or intermediary genotype between C. microphlla Lam. and C. arborescens Lam., or between C. purdomi Rehd. and C. arborescens Lam.; either may be the different species with progressive increasing haploid chromosome number.
