Abstract

The presented dendroclimatological study on Teak (Tectona grandis L.) was carried out in northern Thailand by using earlywood vessel density and latewood conductive area and other anatomical variables. The vessel density is determined using an image analysis system. The anatomical variables are used to calibrate and verify temperature during the March period. The regression equation explains about 44% of the relationship among calibrated variances. The study also suggests that a more detailed study of El Nino via anatomical variables and tree-ring widths might be possible.
