To analyze carbon dynamics between leaves and the other plant parts, we developed a compartment model and compared the differences between canopy-layer species and underlayer species in Dry Evergreen Forest (DEF) in Thailand. Hydnocarpus ilicifolius was selected as a canopy species and Glycosmis parva as an underlayer species. Using our model, the carbon export rate was estimated by subtracting the changes in carbohydrate content from carbon gain by photosynthesis during a continuous 24-hour period. The results for H. ilicifulius suggested that assimilated carbon was stored as starch in the morning, but as monosaccharide for the rest of the daytime. Carbon export occuned not only in the night, but also during the day when the light intensity was low for H. ilicifulius. In the case of G. parva, the translocation occurred the most of the 24-hour period, with the highest carbon export during periods of sunflecks. Thus, translocation of carbon appeared to occur during night and under Iow light intensity in both species. Furthermore, the accumulated carbohydrate might change the form against the environmental changes. Our study showed that carbon flow in tree species could be more flexible than has generally been thought and that the dynamics differed between H. ilicifulius and G. parva.
