In Vitro Propagation of Dendrobium chrysotoxum (Lindl.)
In vitro asymbiotic seed germination of Dendrobium chrysotoxum varied with fruit harvesting time and culture medium used for germinating seeds. Seeds at different developmental stages were harvested and cultured on five asymbiotic orchid seed germination media i.e. defined and undefined media, namely 1⁄2 MS, KC, M, MS and PDA. Seeds harvested 220 days after pollination showed maximum germinatio...

Anther primordium of Malaxis muscifera (Lindl.) Kuntze initiated as a homogenous mass of meristematic cells is surrounded by protoderm. Two thecae are oriented towards the labellum, each of them consisted of a mass of archesporial cells. The hypodermal layer of sporogenous cells divide periclinally to form an endothecial, a middle layer and a tapetum. Pollen mother cells formed different types ...
