本研究利用最优控制理论来预测一年生植物的最优碳分配计划应包括在生长季节的某个时间点分配到储存的条件。最优分配调度被定义为最大化最终种子集的调度。碳的储存，以及后来的再动员分配到繁殖，是模型中的一个选项，通过提供选项，提出了一个问题，即碳的储存是否是一年生植物的最佳选择。从模型的预测进行了测试，通过比较观察到的差异之间的分配的2个季节性生态类型的草地杂类草[Hemizonia luzulifolia]的最佳行为预测的差异。该模型预测，秋季生态类型应该储存碳，而春季生态类型不应该。这些预测定性同意的模式，在2个生态型，总的非结构性碳水化合物，这是存储的措施。模型的分析表明，负责不同的预测为2个生态型的参数是生殖（种子质量）损失率。
This study uses optimal control theory to predict the conditions under which an annual plant''s optimal schedule of carbon allocation should include allocation to storage at some point during the growing season. The optimal allocation schedule is defined as the schedule that maximizes final seed set. Storage of carbon, and later remobilization for allocation to reproduction, is an option in the model, and by providing the option, the question is raised whether storage of carbon is ever optimal for annuals. Predictions from the model are tested by comparing the observed differences in allocation between 2 seasonal ecotypes of grassland forb [Hemizonia luzulifolia] with differences in the optimal behavior predicted for each. The model predicts that the autumnal ecotype should store carbon, while the vernal ecotype should not. These predictions qualitatively agree with the patterns, in the 2 ecotypes, of total nonstructural carbohydrate, which is the measure of storage. Analysis of the model indicates that the parameter responsible for the different predictions for the 2 ecotypes is the reproductive (seed mass) loss rate.
