| 摘 要： | 金花茶(Camellia petelotii)的小孢子单核期花药，经培养和继代培养6个月后的愈伤组织中，发现有少量体细胞进行减数分裂。在减数第一和第二次分裂中，同源染色体的配对和分离基本正常，最后形成四分体。该愈伤组织经石蜡切片和压片观察，发现其主要由大量的液化细胞和贮藏细胞所组成，此外，还有少部分分生细胞。没有发现进一步的分化。其染色体数目，2n=30者占71.7%其余则为非整倍体。

| Abstract: | The newly discovered diploid type of C. reticulata was distributed in Jinshajiang valley with an elevation of 1650-2800 m, which is situated in Huaping of Yunnan province and Yanbian of Sichuan province. This diploid occured in the habitat with higher humidity. Its vege-tation was mainly consisted of evergreen broad-leaved forest and Pinus yunnanensis forest. |
