| Abstract;Chromosome numbers and karyotypes of 15 species of Impatiens collected from south and northwestern Yunnan, China, were investigated. Nine of them were examined for the first time. As a result, seven different chromosome numbers were counted: 2n=14 in Impatiens kamtilongensis and I. wuchengyihii; 2n=16 in I. mengtszeana; 2n=18 in I. corchorifolia, I. luchunensis, I. maguanensis, I. porphyrea, I. racemosa, I. radiata, I. ruiliensis, and I. uliginosa; 2n=20 in I. arguta; 2n=34 in I. clavigeroides; 2n=36 in I. linearisepala; 2n=40 in I. rubrostriata. Of the eight species with 2n=18, I. corchorifolia only has a monomodal karyotype, while the seven others are characterized by having a bimodal karyotype in common. Based on present and previous studies we discuss karyological characteristics of Impatients in Yunnan. (author abst.) |
