Morphogenesis of shoot renewal in pre-winter period in bulbous and corms ephemeroids

The aim of the study was comparative analysis of the morphogenesis of bulbous and tuberous ephemeroids to identify the state of shoot renewal in pre-winter in the forest-steppe zone of Novosibirsk Region. The features of organogenesis of shoot renewal from early-flowering bulbous and bulbotuberiferous geoview were analyzed. The description of generative apex of root from seven species: Erythronium sibiricum, Chionodoxa gigantea, Muscari armeniacum, M. aucheri, Puschkinia scilloides, Scilla sibirica, Crocus hybridus was presented. It was established that these species were characterized by a short early spring aboveground development of shoot renewal within 1.5 months preceded by a long underground development for 22-23 months. The conclusion was made that in generative period of ontogenesis in studied plants in pre-winter period there was the correlation of differentiation of the cone of growth of the shoot of renewal to certain stages of organo- genesis. The species flowering in early spring Muscari aucheri, hybridus, Crocus, Chionodoxa gigantea, Scilla sibirica, Eryhtronium sibiricum before winter forced the rest of the bulbs and corms to have the shoot of a resume-formed organs of the flower and inflorescence, which determined their state of VI-VIII stages of organogenesis...
