Abstract

The results of studies of the characteristics of the water regime of 18 species of the genus Dianthus L. (D. acicularis, D. anatolicus, D. andrzejowskianus, D. borbassii, D. deltoides f. rubra, D. carthusianorum, D. chinensis, D. crossopetalus, D. giganteus, D. gratianopolitanus, D. hypanicus, D. japonicus, D. knappii, D. nardiformis, D. oshtenicus, D. plumarius, D. seguieri, D. uralensis) in the conditions of the South-Ural Botanical Garden-Institute of the UFRC RAS. The experiments were carried out during the growing seasons 2021–2023 on the basis of the laboratory of introduction and selection of flower plants. During the research, the seasonal dynamics of such water regime indicators as total water content, water-holding capacity and leaf water deficit were determined. The analysis of water regime parameters is based on the method of artificial wilting and the technique of saturation of plant samples. The obtained data were processed using standard statistical methods using Microsoft Excel 2003. It was revealed that as a result of the study, the studied taxa are characterized by high water-holding capacity. All of them are adapted to dry periods under cultivation conditions in the forest-steppe zone of the Bashkir Cis-Urals.
