Ex 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 کاملIn vitro propagation of Vanda testacea ( Lindl . ) Reichb . f . – a rare orchid of high medicinal value
The present studies report in vitro propagation of a rare and medicinally important orchid Vanda testacea through foliar explants. Explants were cultured on Mitra et al. (M) medium and its combinations with cytokinins (BAP, Kn 1 mgl each) and auxin (NAA 1 mgl) individually and in combination for initiation of regeneration response, proliferation of regenerants and subsequent development of plan...
متن کاملIn 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 کاملSeed germination and vigor.
Germination vigor is driven by the ability of the plant embryo, embedded within the seed, to resume its metabolic activity in a coordinated and sequential manner. Studies using "-omics" approaches support the finding that a main contributor of seed germination success is the quality of the messenger RNAs stored during embryo maturation on the mother plant. In addition, proteostasis and DNA inte...
متن کاملSeed dormancy and germination.
Seed dormancy and germination are complex adaptive traits of higher plants that are influenced by a large number of genes and environmental factors. Studies of genetics and physiology have shown the important roles of the plant hormones abscisic acid and gibberellin in the regulation of dormancy and germination. More recently, the use of quantitative genetics and mutant approaches has allowed t...
