A plant growth model developed by Volk and colleagues was modified to partition plant mass production after anthesis into grain and inedible biomass. Using data on wheat (Triticum aestivum) grown in the NASA CELSS Biomass Production Chamber to supply constants for the model, we showed that delaying the date of anthesis 7 days resulted in a 20% decrease in the harvest index. Multiple model components were then assembled to demonstrate the effect of an environmental system failure.
沃尔克及其同事开发的植物生长模型经过修改，用于划分开花后植物生物量的生产，分为籽粒和不可食用生物量两部分。利用美国国家航空航天局（NASA）受控生态生命支持系统（CELSS）生物量生产舱内种植小麦（普通小麦）的数据为该模型提供常数，我们发现，将开花日期推迟7天会导致收获指数下降20%。然后组装了多个模型组件来演示环境系统故障的影响。
