本文报道了9种2变山茶属植物的核型. 结果如下: Camellia henryana: 2n=2x=30=21m+8sm+1st; C. furfuracea: 2n=2x=30=20m+10sm; C. wardii: 2n=2x=30=18m+11m+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. pyxidiacea 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. 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.
