| 为探讨常绿阔叶林常见种幼苗非结构性碳水化合物（NSC）及其组分含量的种间差异及其在根、
茎、叶不同器官中的分配格局，以流溪河森林公园常绿阔叶林15 种常见种幼苗为研究对象，分别测定其根、
茎、叶的可溶性糖、淀粉、非结构性碳水化合物的含量和可溶性糖/ 淀粉的比值。结果表明，物种、植物器官及
其交互作用对植株非结构性碳水化合物及其组分含量具有显著影响；15 种植株幼苗普遍表现为叶片的可溶性
糖和可溶性糖/ 淀粉比值最高，根部的淀粉和非结构性碳水化合物含量最高；乔木树种幼苗和灌木树种幼苗的
NSC 及其组分含量在植物根部和叶片中无显著差异，乔木和灌木树种幼苗茎的可溶性糖与NSC 含量也无显著
差异，但常绿乔木的茎可溶性糖/ 淀粉显著高于灌木，淀粉含量显著低于灌木。常绿阔叶林常见种幼苗的NSC
及其组分含量的种间差异及其在不同器官中的分布差异，体现了植株幼苗的叶和根分别是非结构性碳水化合
物的合成与储存结构，为植株的生长发育提供营养物质，同时也反映了其应对环境的不同生存策略。 |

| In order to study the interspecific differences and allocation pattern of non-structural carbohydrate（ NSC）
among roots，stems and leaves and its component about common species seedlings of evergreen broadleaved forest，15
common species seedlings of evergreen broadleaved forest in Liuxihe Forest Park were investigated. The concentration of
soluble sugar，starch，NSC and the ratio of soluble sugar and starch of roots，stems and leaves were studied. The results
showed that significant differences were found among species and significant interaction was existed among species and
plant organs（ P< 0.05）. 15 seedlings of common species generally showed that the content of soluble sugar and the ratio
of soluble sugar and starch of leaves were the highest，while the starch and NSC content of roots were the biggest. There
was no significant difference of NSC and its component in roots and leaves of tree seedling and shrub seedlings. There
was no significant difference of soluble sugar and NSC
content in stems of tree and shrub seedlings. But the ratio
of soluble sugar and starch in stems of tree was significant
higher than that of shrub，while its starch content was
significant lower than shrub. Interspecific differences
and allocation pattern of non-structural carbohydrate for
seedlings of common species in evergreen broadleaved
forest reflected that leaves and roots of plants seedlings
were the synthesis and storage structure of NSC，which could provide nutrients for the growth and development of plants. Also，it reflected their different survival strategies to
deal with the environment. |
