Himantoglossum affine is a threatened terrestrial orchid. We aimed to optimize asymbiotic seed germination and direct embryogenesis analyze the phytochemical profile physico-biochemical analysis of leaf tuber. The individual use organic nitrogen compounds resulted in higher efficiencies, while shortest times were observed using coconut water plus casein hydrolysate. Plantlets grown on media sup...

Abstract Generally, orchids produce dust-like seeds in which endosperm reduction and embryo undifferentiation represent a derived state shared with species about 11 other plant families. Orchid are proposed to have special kind of morphological or morphophysiological dormancy. We test this proposition, overcoming several design limitations earlier studies, specifically that the vitro germinatio...

In vitro, a new protocol of plant regeneration in rose was achieved via protocorm-like bodies (PLBs) induced from the root-like organs named rhizoids that developed from leaf explants. The development of rhizoids is a critical stage for efficient regeneration, which is triggered by exogenous auxin. However, the role of cytokinin in the control of organogenesis in rose is as yet uncharacterized....

Renanthera imschootiana Rolfe is an endangered tropical epiphytic orchid that is threatened with extinction due to over-collection and the loss of suitable habitats. In vitro propagation is a useful way to mass produce plants for re-establishment in the wild and for commercial propagation. Seeds collected 150 days after pollination (DAP) were the optimum stage for in vitro culture. Seed germina...
