Using the expolinear growth equation for modelling crop growth in year-round cut chrysanthemum
Expolinear growth equations comprise biologically meaningful parameters such as maximum relative growth rate and maximum growth rate. Lee et al. (697-708) build a simple empirical model of crop growth rate for year-round cut chrysanthemum by using a rectangular hyperbolic relationship with daily incident photosynthetically active radiation (PAR). The model is shown to estimate dry mass production closely in several independent experiments, using leaf area index and daily incident PAR as inputs.
