【目的】

探究雌雄异株植物碳水化合物的差异机制，解析绒毛白蜡Fraxinus velutina不同性别植株在不同发育阶段的碳水化合物分配模式的差异，为性二态植物碳代谢调控与城市森林经营提供科学依据。

【方法】

分别在植株坐果期（S1）、果实膨大期（S2）、果实成熟期（S3）进行采样，测定其非结构性碳水化合物与结构性碳水化合物含量。

【结果】

发育阶段及其与性别的交互作用对结构性碳水化合物和部分非结构性碳水化合物含量影响显著（P<0.05）。绒毛白蜡雌雄株叶片纤维素含量呈先升后降趋势，S1时期雌株显著低于雄株；雌雄株木质素含量持续下降，雌株各阶段木质素含量均低于雄株，S2时期差异显著（P<0.05）。非结构性碳水化合物方面，雌株淀粉含量从S1到S2时期下降程度明显，S2时期雌株显著低于雄株（P<0.05）；果糖含量先降后升，S2时期雌株显著低于雄株；蔗糖含量先降后升，S2时期雌株显著低于雄株（P<0.05）。相关性分析表明，雌株纤维素与淀粉、可溶性糖等非结构性碳水化合物多呈负相关，雄株淀粉与可溶性糖及其组分多呈正相关，体现出碳代谢协同性与碳分配权衡策略。

【结论】

绒毛白蜡雌雄株因生活史策略分化，在发育进程中呈现碳水化合物分配的性别差异：雄株叶片结构性碳水化合物（纤维素、木质素）含量整体偏高，以结构性碳水化合物优势支撑营养生长，雌株对非结构性碳水化合物（淀粉、可溶性糖）的调动更灵活，通过非结构性碳水化合物的动态调控适应生殖需求。

【Objective】

To explore the differential mechanisms of carbohydrates in dioecious plants, this study took Fraxinus velutina as the research object. It aimed to analyze the differences in carbohydrate allocation patterns between male and female plants at different developmental stages, thereby providing a scientific basis for the regulation of carbon metabolism in sexually dimorphic plants and the management of urban forests.

【Method】

Specimens were gathered during the fruiting phase (S1), fruit expansion period (S2), and fruit ripening stage (S3). Branches in the upper southern section of the trees were tested to determine the levels of non-structural and structural carbohydrates.

【Result】

Growth stages and their combined effect with gender notably affect structural carbohydrates and some non-structural carbohydrates (P<0.05). In both genders of F. velutina, leaf cellulose content first increases and then decreases, with females showing significantly lower levels than males at S1. Lignin content declines steadily, and females have lower levels in all stages, with a marked difference at S2 (P<0.05). Regarding non-structural carbohydrates: female starch content drops dramatically from S1 to S2 and is significantly lower than that of males at S2 (P<0.05); fructose content first decreases and then increases, with females were significantly lower at S2; sucrose content follows a similar trend, with females showing significantly lower levels at S2 (P<0.05). Correlation analysis indicates that in females, cellulose is mostly negatively associated with non-structural carbohydrates (such as starch and soluble sugars), while in males, starch is mostly positively associated with soluble sugars and their components. This reflects gender-specific coordination in carbon metabolism and trade-off strategies in carbon allocation.

【Conclusion】

Owing to distinct life history strategies, male and female F. velutina exhibit differences in carbohydrate allocation during development: males retain higher levels of structural carbohydrates in leaves, relying on the advantages of cellulose and lignin to support vegetative growth; females display more adaptable mobilization of non-structural carbohydrates, adjusting starch and soluble sugars dynamically to meet reproductive needs.
