A model of an annual plant is developed in which it is assumed that photosynthate can be allocated to new leaves or seeds, or stored for subsequent allocation to reproduction. Photosynthetic rate and reproductive efficiency are allowed to vary seasonally with the period of maximum photosynthesis preceding the date of maximum reproductive efficiency. Using methods from optimal control theory, the model is solved and the circumstances favoring the storage of materials determined.-Authors
