Results of the study of vegetative propagation of representatives of the genus Hemerocallis L. in the South Ural Botanical Garden-Institute of the Ufa Federal Research Center of the Russian Academy of Sciences

 The article summarizes the results of the study of the ability of some species and varieties of the genus Hemerocallis L. to vegetative reproduction, introduced into the South Ural Botanical Garden-Institute, a separate structural division of the Federal State Budgetary Scientifi c Institution of the Ufa Federal Research Center of the Russian Academy of Sciences, as a valuable economic trait of plants when used in landscaping. The objects of the study were 6 species and 43 varieties of the genus Hemerocallis L. As a result of the studies, it was found that in the conditions of the forest-steppe zone of the Bashkir Cis-Urals, one year after planting the vegetative reproduction coeffi cient of daylily species is 6.12±0.77, two years later – 14.07±1.98, and three years later – 20.65±2.92. In daylily varieties, this indicator after one year is 3.50±0.28, after two – from 7.73±0.51, after three – from 11.31±1.05. Among species, the maximum vegetative reproduction coeffi cient is possessed by H. middendorfi i, the minimum – by H. fulva, among the varieties ‘Mini Stella’ and ‘Always Liberty’, respectively. It was found that the number of vegetative and generative shoots of daylily species and varieties are reliably associated with the factor of the year of vegetation and the genetic characteristics of the plants.
