Summary
Seasonal variation in the biomass and total non-structural carbohydrate content (TNC) of fine roots of teak (Tectona grandis L. f.) were studied in 19- and 29-year-old plantations in a dry tropical region. Fine root TNC content was highest during
the dry summer (May), and lowest in the early part of the
rainy season (July). Generally, seasonal trends in TNC content were the opposite of those in fine root biomass. The TNC concentration
of roots increased with diameter and decreased with soil depth. In the 19-year-old plantation, fine root TNC content was approximately
12% higher than in the 29-year-old plantation.
