6种1变种猕猴桃植物染色体数目的研究

STUDY ON CHROMOSOME NUMBERS OF 6 SPECIES AND 1 VARIETY IN ACTINIDIA LINDL

摘要: 报道了猕猴桃属6种1变种体细胞染色体数目,表明湖北猕猴桃、浙江猕猴桃、黄毛猕猴桃为二倍体,2n=2x=58;大花猕猴桃为四倍体,2n=4x=116;绿果猕猴桃(美味猕猴桃的1个变种)为四倍体,染色体数目2n=4x=116,以上均为首次报道。并再次证实x=29应是本属染色体数目的基数,狗枣猕猴桃和阔叶猕猴桃二倍体类型2n=58

Abstract: It is reported in this paper the chromosome number of 6 species and 1 variety in Actinidia Lindl, showing that A.hubeiensis, A.zhejiangensis and A.fulvicoma are diploid, 2n＝2x＝58; A.grandiflora is a tetraploid, 2n＝4x＝116; A.deliciosa var.chlorocarpa is a tetraploid, 2n＝4x＝116.The above results are all reported for the first time,which has verified again that x＝29 should be the basic number of chromosomes in this genus,and the diploid type of A.latifolia and A.kolomikta is 2n＝2x＝58.
