Analysis of the variability of the quantitative traits of the generative shoot of two white-flowered carnation species (Dianthus awaricus, Dianthus fragrans) under the conditions of Dagestan
Abstract:The paper presents the results of assessing the quantitative traits of generative shoots of two white-flowered carnation species from four geographically isolated points: Dianthus awaricus (Oboda, Khvarada) and Dianthus fragrans (Khindakh, Charoda). Comparative analysis showed that, in general, the average values of most morphological characters are higher in D. fragrans, and the width of the petal and the number of lobe denticles are higher in D. awaricus. According to the results of two-way analysis of varia… Show more
“…The study of the complex of morphological traits of the generative shoot of plants explains, in some cases, the features of the life cycle of plants, the ecological differences in different habitats of the species, and the ability to self-maintain in natural populations [14][15][16].…”
The paper presents the results of studying the variability of the morphological traits of the generative shoot Matthiola caspica (Busch) Grossh. in Piedmont Dagestan. The material for the study was the life processes of M. caspica of three cenopopulations: Buynaksky (Talgi, 270), Suleiman-Stalsky (Kasumkent, 410 m) and Tabasaransky (Maraga, 520 m) areas. The greatest contribution to the differentiation of cenopopulations by individual components of dispersion in the traits “length inflorescence” (39.9%), “length vegetative features” (38.5%), “number flowers” (37.1%) and index trait “density inflorescences” (16.5%). The distinctions revealed as a result of the discriminates analysis make it possible to select diagnostic characters that introduce specific differences in M. caspica cenopopulations within the Piedmont floristic region. The total accuracy of the classification matrix for the three studied cenopopulations was 82.2%, where the “Maraga” cenopopulation (90.0%) is highly self-identical.
