Dendrobium sp.: In vitro Propagation of Genetically Stable Plants and Ethnomedicinal Uses

Abstract

Plants belonging to the Dendrobium genus occupy a dominant position among the orchids because of their high ornamental and therapeutic values. They are widely popular in the international floriculture trade as they bear stunning flowers with diverse coloration, varied forms, and patterns. The ethnomedicinal uses of these orchids are also prominently found due to the possession of immense medicinal properties. Excessive exploitation through rampant unregulated

Exploring island syndromes: Variable matrix permeability in Phalaenopsis pulcherrima (Orchidaceae), a specialist lithophyte of tropical Asian inselbergs

“…Our estimates of number of migrants per generation (Nm) between populations throughout the region ranged from 0.229-1.080 and the mean was less than 1, suggesting that genetic divergence is marked and could become progressively entrenched (Luo et al, 2019). However, whilst low compared with other similarly widespread (but more generalist) orchids (Simmons et al, 2017;Tikendra et al, 2021), these values are comparable to or even higher than those calculated for several other terrestrial habitat specialists (Rossetto et al, 2008;Mallet et al, 2014;Nistelberger et al, 2015;Lexer et al, 2016). Moreover, Nm estimates were significantly higher among populations belonging to each of the two genetic clusters (Nm = 1.295 for HN group, Nm = 0.961 for IC group) than the mean for the species as a whole, suggesting greater gene flow at the scale of either landmass.…”

Orchid Micropropagation Using Conventional Semi-Solid and Temporary Immersion Systems: A Review

“…The addition of organic supplements in the culture media had a promotory effect on in vitro seed germination and culture growth in some orchids [52][53][54]. Incorporating plant growth regulators is vital for the success of orchid micropropagation as they enhance culture growth with cytokinins promoting shoot initiation, proliferation, and plant regeneration and auxins accelerating root induction and multiplication [55,56]. Plant growth regulators may improve tissue development but show adverse effects at particular elevated concentration.…”

“…Kaur and Bhutani [60] also stated the favorability of young tissues of explants over mature ones as they possess high regeneration capability. Explants established from in vitro-raised plants are preferred over those derived from in vivo plants as they are not contaminated and have more significant differentiation potential [56].…”
