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 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 کاملEffects of culture medium and supplementation on seed germination, protocorm formation and regeneration of some Phalaenopsis hybrids
An efficient protocol is suggested for in vitro culture of five Phalaenopsis hybrids obtained by hand-cross-pollination of three commercial hybrids Calgary, Ankara, and Kendall. Four nutrient media- namely half-strength Murashige and Skoog, Knudson, Phytamax containing activated charcoal, and Mitra– once supplemented (with coconut water, peptone, or both), and once without any supplement were c...
متن کاملEffects of organic additives and different carbohydrate sources on proliferation of protocorm- like bodies in Dendrobium
The purpose of this study was to investigate the effect of the addition of different organic additives and sugar types as carbon source on the growth and proliferation of protocorm-like bodies (PLBs) of a very new Dendrobium hybrid known as D. Alya Pink (DAP). PLBs were supplemented with homogenates of banana, tomato, and coconut water at various concentrations. Proliferation rate was recorded ...
متن کاملEmbryo development in association with asymbiotic seed germination in vitro of Paphiopedilum armeniacum S. C. Chen et F. Y. Liu
This paper documents the key anatomical features during the development of P. armeniacum zygotic embryos and their ability to germinate asymbiotically in vitro. This study also examines the effect of media and seed pretreatments on seed germination and subsequent seedling growth. Seeds collected from pods 45 days after pollination (DAP) did not germinate while 95 DAP seeds displayed the highest...
