The seasonal patterning of carbon gain and allocation was studied in the California evergreen sclerophyll shrub, Heteromeles arbutifolia. Specifically an analysis was made of the seasonal structural allocations to stems, leaves, roots and reproductive parts as well as to functional categories of cell structure, metabolism, storage, and secondary compounds (predator protection).The differential partitioning during the various seasons is viewed in terms of the overall carbon economy of the shrub. It is suggested that not all functions can be met simultaneously, even though there is year round carbon gain, because of the heavy allocation demands to meet a particular environmental stress during a given season. For example, during the spring there is a priority allocation to the development of the canopy, apparently for competitive purposes, with little going to reproduction, storage and secondary compounds.
对加利福尼亚常绿硬叶灌木山楂叶悬钩子的碳获取和分配的季节性模式进行了研究。具体而言，分析了茎、叶、根和生殖部分以及细胞结构、代谢、储存和次生化合物（捕食者保护）功能类别的季节性结构分配。从灌木的整体碳经济角度来看不同季节的差异分配。研究表明，尽管全年都有碳获取，但由于在特定季节满足特定环境压力的分配需求很大，并非所有功能都能同时得到满足。例如，在春季，优先将资源分配给树冠的发育，显然是为了竞争，很少分配到繁殖、储存和次生化合物方面。
