Recent studies of allocation to defensive chemicals in plants have provided insights into the ecological controls over plant defensive chemicals. Both developmental and ecological studies now suggest that we can understand the factors influencing allocation to defense by examining the relative availability of resources, external needs for chemical defense, and the internal demands for growth that plants face. These studies have also shed light on one of the more popular theories in plant evolutionary ecology, the growth-differentiation balance hypothesis of plant resource allocation.
最近对植物防御性化学物质分配的研究为我们提供了对植物防御性化学物质的生态控制的深入了解。发展和生态研究现在表明，通过检查资源的相对可利用性、对化学防御的外部需求以及植物面临的生长的内部需求，我们可以理解影响防御分配的因素。这些研究还揭示了植物进化生态学中更受欢迎的理论之一，即植物资源分配的生长-分化平衡假说。
