摘　　要：为了提高气孔保卫细胞叶绿体计数法鉴定烟草花粉植株染色体倍性的效率,对烟草植株染色体数与气孔保卫细胞叶绿体数的相关性进行了研究.结果表明,各倍性烟草植株气孔保卫细胞叶绿体数平均值之比符合相应倍性间的染色体数的比值;叶绿体数的分布服从正态分布.In order to increase the efficiency of the method of using count stoma protective cell chloroplast in the identification of tobacco pollen plant chromosomes ploidy, a study on the correlation between tobacco pollen plant chromosomes ploidy and the number of stoma protective cell chloroplast was carried out. The result showed that the ratio of average number of stoma protective cell chloroplast in tobacco plants with different ploidy matched the ratio of chromosomes number with respective ploidy ; the distribution of chloroplast was normal distribution.
