1. Temperate trees rely on carbon (C) and nutrient remobilization from storage to resume growth after winter. Minimum storage levels during the growing season suggest that remobilization could signify that C availability is insufficient to meet growth demands; consequently, growth might be C and/or nutrient limited. However, it remains unclear whether higher growth demands are covered by higher remobilization. This study examined whether higher C and nutrient demands associated with fast growth or deciduousness rely on greater remobilization.
2. In 11 sympatric deciduous and evergreen angiosperm tree species from southern South America, the magnitude of seasonal remobilization of C and nutrient storage was assessed as the seasonal minimums (relative to seasonal maximums) of whole‐tree non‐structural carbohydrates (NSCs), nitrogen (N) and phosphorus (P) concentrations and pools. The basal area increment and stem wood density were determined for each tree, from which the biomass radial increment (BRI) was estimated. The effects of leaf habit and BRI on the seasonal minimum NSC and nutrient concentrations and pools were analysed using linear mixed effects models.
3. Radial growth was not related to seasonal minimum NSC or nutrient concentrations and pools in either the evergreens or deciduous angiosperms; thus, faster growth was not associated with greater remobilization of C or nutrient stores. Furthermore, larger trees grew faster than smaller ones, but did not have higher remobilization. Deciduous species had higher year‐round whole‐tree NSC and nutrient concentrations than evergreens; however, both groups had similar BRI and seasonal minimum concentrations and pools of NSCs and nutrients.
4. Neither growth rate nor leaf habit drove the magnitude of C and nutrient remobilization in the angiosperm trees examined here, indicating no C or nutrient limitation. This result contradicts the view that growth and storage strongly regulate one another, as proposed by a growth‐storage trade‐off.

阔叶温带树种的生长速度与贮藏迁移之间的解耦

1. 温带树木依靠碳（C）和养分从存储中转移出来，以在冬季后恢复生长。生长季节的最低储存水平表明，迁移可能表明碳的有效性不足以满足增长需求；因此，生长可能受到碳和/或营养的限制。但是，目前尚不清楚更高的动员能否满足更高的增长需求。这项研究检查了与快速生长或落叶相关的更高的碳和养分需求是否依赖于更大的迁移。
2. 在南美洲南部的11种同伴落叶和常绿被子植物树种中，碳和养分储量的季节性迁移量被评估为全树非结构性碳水化合物（NSC），氮（ N）和磷（P）的浓度和池。确定每棵树的基础面积增加量和茎木密度，据此估算生物量径向增加量（BRI）。使用线性混合效应模型分析了叶习性和BRI对季节性最低NSC和养分浓度和库的影响。
3. 在常绿或落叶被子植物中，径向生长与季节性最低NSC或养分浓度和养分含量无关。因此，更快的生长与碳或养分库的更大迁移无关。此外，大树的生长快于小树，但没有更高的迁移率。落叶树种全年的全树NSC和养分含量均高于常绿树种。但是，两组的BRI和季节性最低浓度以及NSC和养分含量均相似。
4. 此处研究的被子植物树木的生长速度和叶片习性都没有推动碳和养分迁移的幅度，表明没有碳或养分限制。这一结果与以下观点相矛盾，即增长与存储之间存在严格的调节关系，正如增长与存储之间的权衡所提出的那样。
