| Popis: | The study aimed at investigating the anatomic and DNA content characteristics of 12 Anthurium genotypes. A large genomic amplitude was observed in the genotypes, ranging from 4.95 to 22.74 pg of DNA. Differences in DNA content, assessed by flow cytometry, allowed the differentiation between the genotypes A. andraeanum, A. affine, A. bomplandii, and A. gracile and the hybrid (A. lindmanianum × A. guianesis) and clustered the group A. raimundii, plowmanii and jemanii of IFT 258, in all analyses. Anatomical studies clustered the genotypes A. andraeanum (Astral and Rubi) and distinguished the hybrid and A. bomplandii from the other genotypes, with anatomical features specific to each genotypes. Cluster analysis allowed grouping of the genotypes A. raimundii and A. affine, bomplandii and gracile, A. jemanii and plowmanii, and the cultivars Astral and Rubi, and isolated the hybrid. Demonstrated the importance of grouping in the diagnosis of species belonging to the genus Anthurium. |
