摘　　要：本文报道了９种２变山茶属植物的核型．结果如下：Ｃａｍｅｌｉａｈｅｎｒｙａｎａ：２ｎ＝２ｘ＝３０＝２１ｍ＋８ｓｍ＋１ｓｔ；Ｃ．ｆｕｒｆｕｒａｃｅａ：２ｎ＝２ｘ＝３０＝２０ｍ＋１０ｓｍ；Ｃ．ｗａｒｄｉ：２ｎ＝２ｘ＝３０＝１８ｍ＋１１ｍ＋１ｓｔ；Ｃ．ａｎｌｕｎｇｅｎｓｉｓ：２ｎ＝２ｘ＝３０＝１９ｍ＋９ｓｍ＋２ｓｔ；Ｃ．ａｎｌｕｎｇｅｎｓｉｓｖａｒ．ａｃｕｔｉｐｅｒｕｌａｔａ：２ｎ＝２ｘ＝３０＝１９ｍ＋９ｓｍ＋２ｓｔ；Ｃ．ｐｙｘｉｄｉａｃｅａ：２ｎ＝２ｘ＝３０＝２０ｍ＋８ｓｍ＋２ｓｔ；Ｃ．ｐｙｘｉｄｉａｃｅａｖａｒ．ｒｕｂｉｔｕｂｅｒｃｕｌａｔａ：２ｎ＝２ｘ＝３０＝２１ｍ＋８ｓｍ＋１ｓｔ；Ｃ．ｂｒｅｖｉｓｔｙｌａ：２ｎ＝２ｘ＝３０＝１８ｍ＋１０ｓｍ＋２ｓｔ；Ｃ．ｌｅｐｔｏｐｈｙｌａ：２ｎ＝２ｘ＝３０＝２４ｍ（１ｓａｔ）＋４ｓｍ（１ｓａｔ）＋２ｓｔ；Ｃ．ｙｕｎｎａｎｅｎｓｉｓ：２ｎ＝２ｘ＝３０＝１８ｍ＋１０ｓｍ＋２ｓｔ；Ｃ．ｐｉｔａｒｄｉ：２ｎ＝２ｘ＝３０＝１８ｍ＋１２ｓｍ．其中，前７种２变种的核型为首次报道，比较前人的有关研究可以看出上述核型在种间较相似，以组为单位进行比较比种间比较具有更大的意义。In present paper, The karyotypes of nine species and two varieties of the genus Camellia were reported. The results were as following: Camellia henryana: 2n=2x=30=21m+8sm+1st; C. furfuracea: 2n=2x=30=20m+10sm; C. wardii: 2n=2x=30=18m+11sm+1st; C. anlungensis: 2n=2x=30=19m+9sm+2st; C. anlungensis var. acutiperulata: 2n=2x=30=19m+9sm+2st; C. pyxidiacea: 2n=2x=30=20m+8sm+2st; C. pysidiaea var. rubituberculata: 2n=2x=30=21m+8sm+1st; C. brevistyla: 2n=2x=30=18m+10sm+2st; C. leptophylla: 2n=2x=30=24m(1sat)+4sm(1sat)+2st; C. yunnanensis: 2n=2x=30=18m+10sm+2st; C. pitardii: 2n=2x=30=18m+12sm. Nine of them were reported for the first time. Karyotypes were very similar each other among the above species, and comprision between sections was more important than that between species.
