Climatological signals from the annual growth-rings of selected tree species of India

Growth pattern of selected tree species of the Indian region is studied in relation to its local environment. Growth-ring analysis is done for the samples of Teak from Western Ghats and Chir Pine from Nainital region. Ring-width data for the samples show a significant environmental signal. The tree-growth/environment relationship is studied using the response function analysis and multiple linear regression technique. The historical and climatological data on severe droughts in western U.P. hills is examined in relation to the ring-width index values for Chir from the region.
