摘要:

研究了国产毛茛科银莲花族Trib.Anemoneae 17种植物的染色体数目和核型。10种银莲花属
  Anemone L.植物中,1种(西南银莲花A.davidii)为x=8的四倍体(2n=4x=32),5种(匍枝银莲花A.
  stolonifera、草玉梅 A.rivularis、卵叶银莲花A .begoniifolia、水棉花A.hupehensis f. alba、大火草A.tomen-
  tosa)为x=8的二倍体(2n=2x=16),4种(鹅掌草A.flaccida、湿地银莲花A.rupestris、蓝匙叶银莲花
  A.trullifolia var.colestina、拟条叶银莲花A.trullifolia var.holophylla、展毛银莲花A.demissa)为x=7的
  二倍体(2n=2x=14)。罂粟莲花Anemoclema glaucifolium 为x=8的二倍体。6种铁线莲属Clematis L.植
  物(滇川铁线莲C.kockiana、长花铁线莲C.rehderiana、毛茛铁线莲C.ranunculoides、扬子铁线莲C.
  puberula var.ganpiniana、短尾铁线莲C.brevicaudata、金毛铁线莲A.chrysocoma)均为x=8的二倍体。银
  莲花属中x=7的种类的核型彼此十分相似,均由6对大型具中部着丝点的染色体和1对具端部着丝点
  的染色体组成;x=8的二倍体种类的核型与罂粟莲花属和铁线莲属植物的核型十分相似,均由5对大型
  具中部着丝点和3对具端部或近端部着丝点的染色体组成。

Abstract:

The somatic chromosome number and detailed chromosome morphology have been studied in ten species of Anemone, one species of Anemoclema, and six species of Clematis, all from China, namely Anemone davidii Franch. (2n=4x= 32), A. stolonifera Maxim. (2n=2x=16), A. flaccida Fr. Schmidt (2n=2x= 14), A. rivularis Buch.-Ham. (2n=2x= 16), A. begoniifiolia lévl. et Vant. (2n=2x= 16), A. hupehensis Lem. f. alba W. T. Wang (2n =2x = 16), A. tomentosa (Maxim.) Péi (2n=2x= 16), A. rupestris Hook. f. et Thoms. (2n=2x= 14), A. trullifolia var. colestina (Franch.) Finet et Gagnep. (2n = 2x = 14), A. trullifolia var. holophylla Diels (2n=2x= 14), A. demissa Hook. f. et Thoms. (2n=2x= 14), Anemoclema glaucifolium (Franch.) W. T. Wang (2n= 2x= 16), Clematis  kockiana Schneid. (2n= 2x=16), C. rehderiana Craib. (2n = 2x = 16), C. ranunculoides Franch. (2n = 2x = 16), C. puberula var. ganpiniana(Lévl. et Vant. ) W. T. Wang (2n = 2x = 16), C. brevicaudata DC. (2n= 2x= 16), C. chrysocoma Franch. (2n = 2x = 16). The species of x = 8 in Anemone, and those in Anemoclema and Clematis have very similar karyotypes which consist of five pairs of large median-centromeric (rarely one pair of which are submedian-centromeric) and three pairs of subterminalor terminal-centromeric chromosomes.
