Characteristics of reproduction and early stages of development of some species tropical and subtropical orchids

Abstract

The results of perennial investigation, concerning of reproductive biology and ontomorphogenesis of 8 species belonging to three subfamilies of Orchidaceae family: Epidendroideae (Calanthe vestita Lindl., Cattleya aclandiae Lindl., Dendrobium phalaenopsis Fitzg.), Vandoideae (Acacallis cyanea Lindl., Cymbidium hybridum hort., Psychopsis kramerianum (Rchb. f.) H.G. Jones, Phalaenopsis amabilis Bl.), Cypripedioideae (Paphiopedilum insigne Pfitzg.) are given. The main attention was paid to the clarification of the terms of flowering and fructification studied species under greenhouse culture, to the determination of the morphological parameters of seeds, to the study of the characters of the early stages of morphogenesis in vitro.
