Dr. R. Vinolya Kumari*

Abstract

Shorea tumbuggaia is an endemic endangered medicinal important plant species of Dipterocarpaceae family. The present work is aimed to develop a protocol for micropropogation method for rapid and large scale propagation of the Shorea tumbuggaia by using seed. The percentage of germination is high but seedling production is very less of 0.01%. Now this tree facing high risk of extinction in wild due to ecological conditions. Invitro propagation is one of the best alternative method to conserve this plant to some extent. A high rate of success in percentage of germination was obtained by placing healthy seeds on MS medium supplemented with 2 mg/I BAP. The combination of (0.5mg/I) NAA or IAA is more effective in bringing quick germination. Shoot production was greatest in cotyledonary nodal explants on modified MS medium with BAP 5mg/l+ 0.5 mg NAA and the shoots were successfully rooted. There is an urgent need to protect this endemic plant by both Invivo and Invitro methods.
