| 摘 要： | 本文报道反萼银莲花的染色体数目及核型。其核型公式为K(2n)=6m+4sm(1SAT)+4st(1SAT)+2t,按照Stebbins的核型对称性分类标准应属于“2A”型。同时对本属的进化等问题也作了初步讨论。

| Abstract: | This paper reports chromosome number and karyotype analysis of Anemone reflex for the first time in China. The results of karyotype analysis of the materials collected from Taibai Mountain in Shaanxi Province shows that the karyotype formular of it is K ( 2n) = 16 = 6 m+ 4 sm(1SAT)+ 4 st(1SAT)+ 2t. The karyotype of A. reflex belongs to the symmetrical 2 A type according to Steb-bins' classification of asymmetry, thus the species is one of the ancient members of the genus. Some questions about the chromosomal evolution of Anemone are also discussed. |
