As plants develop from seeds to seedlings, juveniles and mature stages, their ontogeny can constrain the expression of resistance to herbivore damage. Nevertheless, ecological and evolutionary theories regarding interactions between plants, herbivores and their natural enemies are largely based on observations and experiments conducted at a single ontogenetic stage. Owing to resource allocation and architectural constraints in plants, and the influence of herbivore foraging behavior, resistance to herbivores is likely to change during plant development. We propose that such changes are likely to occur in a non-linear fashion and suggest that the role of ontogeny should be incorporated as an important factor in new syntheses of plant defense theory.
随着植物从种子发育成幼苗、幼年期和成年期，它们的个体发育会限制对食草动物损害的抗性表达。然而，关于植物、食草动物及其天敌之间相互作用的生态和进化理论，很大程度上是基于在单个个体发育阶段进行的观察和实验。由于植物中的资源分配和结构限制，以及食草动物觅食行为的影响，植物对食草动物的抗性在其发育过程中可能会发生变化。我们提出，这种变化很可能以非线性方式发生，并建议将个体发育的作用作为植物防御理论新综合中的一个重要因素纳入其中。
