Abstract

The present research work is carried out to study the In-vitro protocorm formation of an endangered medicinal orchid Vanda tessellata at different temperature(15C, 20C, 25C, 30C) and pH (4.5, 5.5, 6.5,7.5) . Immature seeds obtained from green pods successfully shown protocorm formation on basal media MS without various combinations of growth hormones. Highest protocorm formation (940.17%) were observed at temperature 20C and pH 5.5 , whereas the medium which is adjusted at temperature 15C, 25C, 30C and pH 4.5, 6.5, 7.5 showed poor protocorm formation.
