1.开发了一个模型来探索有利于大规模开花与延长开花的条件。假设到达植物的传粉者访问该植物上的所有花，花粉的吸收和沉积分别是花和传粉者上的量的恒定部分，种子集受到资源的限制，并且开花没有季节限制。如果传粉者访问的数量是独立的开花策略，那么它是相当无关紧要的有多少花是在同一时间在一个自交不亲和（SC）的物种，而提出花一次是最佳的自交不亲和（SI）的物种。取决于其他参数的值，大规模开花可以是一个进化稳定的策略（ESS），如果实践它的植物吸引更多的传粉者。如果传粉者稀少，花粉传递率低，SC种比SI种更容易发生大规模开花的选择。经验数据进行了讨论，在时间限制下的鲜花介绍的优化。
1. A model is developed to explore conditions that favour mass blooming vs extended blooming. It is assumed that the pollinators arriving at a plant visit all flowers on that plant, that pollen uptake and deposition are constant fractions of amounts on the flower and pollinator, respectively, that seed set is limited by resources, and that there are no seasonal restrictions on flowering.2. If the number of pollinator visits is independent of the flowering strategy, then it is quite immaterial how many flowers are presented at the same time in a self-compatible (SC) species, whereas presenting flowers one at a time is optimal in a self-incompatible (SI) species. Depending on the values of other parameters, mass blooming can be an evolutionarily stable strategy (ESS) if plants that practice it attract more pollinators. Selection for mass blooming is more likely to occur in SC species than in SI species, if pollinators are scarce and if pollen transfer rates are low.3. Empirical data are discussed in relation to optimization of flower presentation under time-constraints.
