Vegetative reproduction features of some representatives of the genus Hemerocallis L.

Abstract

The article presents the results of a study of the vegetative propagation features of 6 species and 43 varieties of daylilies from the collection of the South-Ural Botanical Garden-Institute of Ufa Federal Research Center of the Russian Academy of Sciences in the forest-steppe zone of the Bashkir Cis-Urals. Quantitative and qualitative differences in the renewal shoots of the studied species and varieties were established. Three groups of cultivars were identified according to the vegetative propagation coefficient: low-yielding (‘Cherry Eyed Pumpkin’, ‘Golden Scroll’, ‘Mauna Loa’, etc.), medium-productive (‘Clothed in Glory’, ‘Emerald Joy’, ‘Summer Wine’, etc.), and highly productive (‘Frans Hals’, ‘Sammy Russell’, ‘Stella de Oro’, etc.). Three groups of taxa were also defined by the number of vegetative shoots per unit area: vegetatively mobile (‘Hellbraun mit Gelb’, ‘Kwanso’, ‘Verbesserte’, etc.), loosely bushy (‘Black Prince’, ‘On and On’, ‘Tropical Summer’, etc.), densely bushy (‘Bali Hai’, ‘Bonanza’, ‘Childrens Festival’, etc.). In addition, we identified three groups of taxa that differ in the morphological characteristics of renewal shoots: with powerful (‘Amadeus’, ‘Bela Lugosi’, ‘Cameroon Night’, etc.), medium (‘Always Liberty’, ‘Bourbon Kings’, ‘Campfire Embers’, etc.) and thin (‘Clothed in Glory’, ‘Double River Wye’, ‘Mini Stella’, etc.) vegetative shoots. Species and variety specificity of the studied parameters was noted. 13 taxa with a high coefficient of vegetative reproduction were identified – they can be recommended for industrial cultivation.
