通过引入近交衰退（ID）对幼年和成年植物存活率的影响，我们建立了一个新的雌雄同体多年生植物的理论模型。我们的模型表明，自交率对进化稳定策略（ESS）生殖分配的影响取决于三个参数：（1）自花受精幼鱼相对存活率（SFJRS），（2）自花受精成鱼相对存活率（SFARS），（3）自花受精成鱼生长率，其中SFJRS是自交幼鱼的存活率除以异交幼鱼的存活率，SFARS也是如此。然而，ESS的性别分配随着自交率的增加而减少。这种关系似乎独立的SFJRS，SFARS，和自花受精的成年人的增长率。此外，我们的模型表明，完全异交是一个ESS时，幼年近交衰退（FJID）的分数小于1/2-τ，其中τ是自受精的成年人死亡率造成的ID。相反，完全自交也作为ESS时，FJID大于1/2-τ。这些结果可以解释植物交配策略的多样性和相关的资源分配。
By incorporating the effects of inbreeding depression (ID) on both juveniles and adults survivorship, we developed a new theoretical model for hermaphroditic perennial plants. Our model showed that the effect of the selfing rate on the evolutionarily stable strategy (ESS) reproductive allocation depends on three parameters: (1) the self-fertilized juvenile relative survivorship (SFJRS), (2) the self-fertilized adult relative survivorship (SFARS) and (3) the growth rate of self-fertilized adult, where the SFJRS is the survivorship of self-fertilized juveniles divided by the survivorship of outcrossed juveniles, and likewise for the SFARS. However, the ESS sex allocation decreases as the selfing rate increases. This relationship seems independent of the SFJRS, the SFARS, and the growth rate of self-fertilized adults. Additionally, our model showed that the complete outcrossing is an ESS when the fraction of juvenile inbreeding depression (FJID) is less than 1/2 −τ, whereτis the self-fertilized adults mortality rate caused by ID. In contrast, the complete selfing also acts as an ESS when the FJID is greater than 1/2 −τ. These results could explain the diversity of mating strategies and related resource allocations for plants.
