Plant scientists have sought to maximize the yield of food crops since the beginning of agriculture. There are numerous reports of record food and biomass yields (per unit area) in all major crop plants, but many of the record yield reports are in error because they exceed the maximal theoretical rates of the component processes. In this article, we review the component processes that govern yield limits and describe how each process can be individually measured. This procedure has helped us validate theoretical estimates and determine what factors limit yields in optimal environments.
自农业伊始，植物科学家们就一直致力于使粮食作物产量最大化。有众多关于所有主要农作物创纪录的粮食和生物量产量（每单位面积）的报道，但许多创纪录产量的报道有误，因为它们超过了各组成过程的最大理论速率。在本文中，我们回顾了决定产量上限的组成过程，并描述了如何分别测量每个过程。这一程序帮助我们验证了理论估计，并确定了在最佳环境中限制产量的因素。
