In vitro asymbiotic germination of immature seed and formation of protocorm by Cephalanthera falcata (Orchidaceae).
BACKGROUND AND AIMS Many Orchidaceous species are threatened globally by development and over-collection from their natural habitats for horticultural purposes. Artificial propagation from seeds is difficult in most terrestrial orchids native to temperate regions. Seed production is another limiting factor in the artificial propagation for these species because of the lessened probability of po...
متن کاملIn vitro asymbiotic germination for micropropagation of the recalcitrant terrestrial orchid Chloraea crispa (Orchidaceae)1
PREMISE OF THE STUDY Chloraea crispa is a terrestrial Orchidaceae species native to Chile, characterized by a beautiful and showy inflorescence. The species has a great potential for commercial exploitation in the cut flower industry, but it is essential to improve propagation methods to avoid endangering its natural populations. Because this species is hard to propagate using traditional green...
متن کاملEx situ conservation of Cymbidium eburneum Lindl.: a threatened and vulnerable orchid, by asymbiotic seed germination
The population of many splendid orchids is reducing from their natural habitats at an alarming rate and their conservation is becoming a matter of global concern. Asymbiotic seed germination has been applied for ex situ conservation of rare, endangered and threatened orchid taxa and could provide rapid means their multiplication. In the present study reported here, seeds of an epiphytic and rar...
متن کاملComparative Transcriptome Analysis of Genes Involved in GA-GID1-DELLA Regulatory Module in Symbiotic and Asymbiotic Seed Germination of Anoectochilus roxburghii (Wall.) Lindl. (Orchidaceae)
Anoectochilus roxburghii (Wall.) Lindl. (Orchidaceae) is an endangered medicinal plant in China, also called "King Medicine". Due to lacking of sufficient nutrients in dust-like seeds, orchid species depend on mycorrhizal fungi for seed germination in the wild. As part of a conservation plan for the species, research on seed germination is necessary. However, the molecular mechanism of seed ger...
متن کاملAn Effective Nutrient Media for Asymbiotic Seed Germination and In Vitro Seedling Development of Phalaenopsis ‘Bahia Blanca’
Our study was to develop a rapid and successful method for promoting asymbiotic seed germination and growth and development of protocorm like bodies (PLBs) and subsequent plantlets of Phalaenopsis orchid. Four basal media i.e. Murashige and Skoog (MS), half strength MS (½MS), Knudson C (KC) and, Vacin and Went (VW) supplemented with coconut water and peptone were examined for their effectivenes...
