【摘要】 本试验采用去壁低渗制片法以及BSHG显带流程,对山茶属（Camellia）的窄叶短柱茶（C·fluviatilis）皱果茶（C·rhytidocarpa）和广宁红花油茶（C·semiserrata）三种植物的核型和C—带带型进行了分析比较。结果为:三种植物的染色体数目均为2n=30,按levan等的系统命名法,其染色体核型模式分别为: C·fluviatilis K（2n）=30=14m+14sm+2m₈^sat C·rhytidocarpa K（2n）=30=28m+2m₄^sat C·semiserrata K（2n）=30=18m+8sm+2m₂^sat+2m₅^sat 三种植物的染色体末端带、随体带都大而明显;核仁缢痕带、中间带都不明显,且变化较大。更多还原

【Abstract】 Taken the decellwall hypotonic flaking method and BSHG dominant band flow path, the experiment has analysed and compared the types of nuclei and C-bands of the three plants : C. fluviatilis , C. rhytidocarpa and C. semiserrata in Camellia, The results are as follows : the number of the chromosomes in the three plants are all 2n = 30 According the Levan’s systematical nomination, the models of nuclei are:C.fluvitilis k (2n) = 30= 14m+14sm+2m8satC . rhytidocarpa k (2n) = 30 = 28m+2m4satC. semiserrata k (2n) = 30 = 18+8sm + 2m2sat + 2m6satThe terminal bands, satellite bands of the chromosomes in these three plants are both large and obviousj the nutleolor constrltiction bands and the in tercalavy bands are obscene and easily changeable.更多还原
