Effect of Different pH on In vitro Seed Germination of Vanda tessellata (Roxb.)Hook.Ex.G an Endangered Medicinal Orchid .

Abstract

The present investigation deals with a study of In-vitro seed germination of an endangered medicinal orchid Vanda tessellata at different pH (3.5, 4.5, 5.5, 6.5,). Immature seeds obtained from green pods were successfully germinated on basal media MS without various combinations of growth hormones. Highest seed germination (95±0.17%) were observed at 5.5 pH, whereas the medium which is adjusted at 3.5 and  6.5 pH showed poor seed germination.
