BACKGROUND AND AIMS Ecotypic differentiation has been explored in numerous plant species, but has been largely ignored in the Orchidaceae. Applying a specific germination protocol for widespread seed sources may be unreliable due to inherent physiological or genetic differences in localized populations. It is crucial to determine whether ecotypic differentiation exists for restoration and conse...

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...

orchids are one of the most popular plants in the world and among them phalaenopsis genus have the most sales in a global market. because of its hard propagation, micropropagation technique has been employed recently. in this study, we tried to find out useful protocol for commercial production through in vitro culture. at first, for seed capsules production, flowers were pollinated with hand i...
