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.
在干旱热带地区，对19年生和29年生柚木（柚木）人工林中细根生物量和总非结构性碳水化合物含量（TNC）的季节变化进行了研究。细根TNC含量在干燥的夏季（5月）最高，在雨季初期（7月）最低。一般来说，TNC含量的季节趋势与细根生物量的趋势相反。根的TNC浓度随直径增加而增加，随土壤深度增加而降低。在19年生人工林中，细根TNC含量比29年生人工林高约12%。
