非结构性碳水化合物(NSC)在植物适应环境中起着重要作用。尽管对NSC的季节动态和物种差异进行了广泛的研究，但季节和物种对NSC的相对贡献还不是很清楚。测定了季风常绿阔叶林20种优势树种枯水期和丰水期叶片、枝条、树干和根系中淀粉、可溶性糖、NSC和可溶性糖/淀粉比值的含量。根中NSC和淀粉含量最高，叶中可溶性糖含量最高。淀粉和NSC浓度的季节变化在旱季较高。相反，雨季样品具有较高的可溶性糖浓度和糖/淀粉比。不同树种间的淀粉、可溶性糖和NSC浓度以及糖/淀粉比存在显著差异。大多数树种在旱季具有较高的淀粉和NSC浓度，在雨季具有较高的可溶性糖浓度和糖/淀粉比。重复方差分析表明，淀粉和NSC浓度受季节的影响较大，但季节、品种以及两者的交互作用对淀粉、可溶性糖和NSC浓度的影响显著。
Non-structural carbohydrates (NSC) play important roles in adapting to environments in plants. Despite extensive research on the seasonal dynamics and species differences of NSC, the relative contributions of season and species to NSC is not well understood. We measured the concentration of starch, soluble sugar, NSC, and the soluble sugar:starch ratio in leaves, twigs, trunks and roots of twenty dominant species for dry and wet season in monsoon broad-leaved evergreen forest, respectively. The majority of concentration of NSC and starch in the roots, and the leaves contained the highest concentration of soluble sugar. A seasonal variation in starch and NSC concentrations higher in the dry season. Conversely, the wet season samples had higher concentration of soluble sugar and the sugar:starch ratio. Significant differences exist for starch, soluble sugar and NSC concentrations and the sugar:starch ratio across species. Most species had higher starch and NSC concentrations in the dry season and higher soluble sugar concentration and the sugar:starch ratio in wet season. Repeated variance analysis showed that starch and NSC concentrations were strongly affected by season although the effect of seasons, species, and the interaction of the two on the starch, soluble sugar, and NSC concentrations were significant.
