Climatic Influence on Radial Growth of Pinus Wallichiana in Ziro Valley
RESEARCH COMMUNICATIONS In conclusion, in the present study we have success- Climatic influence on radial growth of fully induced adventitious roots from the leaf explants of A. paniculata. The adventitious roots were cultured in flask- Pinus wallichiana in Ziro Valley, scale suspension cultures using MS medium supplemented Northeast Himalaya with 2.7 μM NAA and 30 g/l sucrose. Adventitious root cultures showed higher biomass as well as andrographolide Santosh K. Shah1, Amalava Bhattacharyya1,* and accumulation capabilities. Our study demonstrates the Vandana Chaudhary2 possibilities of production of andrographolides for com- 1 mercial purposes in a large scale using bioreactor cultures.
