摘　　要：对人工诱变的玫瑰香葡萄 2个品系进行了染色体数目、气孔特征和花粉粒特性等与倍性有关的性状进行了鉴定。结果表明 ,诱变产生的四倍体玫瑰香Ⅰ为 4 4 4型四倍体 ,诱变玫瑰香Ⅱ为 2 4 4型嵌合体。试验还表明 ,利用气孔、花蕾特征、卷须和茎尖染色体计数可有效鉴定变异株。The chromosome number, stomate length, the size of pollen and other characters related with multiploid of artificially induced mutants of Muscate humbury were measured and observed. The result showed that the artificial mutation Ⅰ was whole autotetraploid, and the mutation Ⅱwas 2 4 4 part autotetraploid.
