A phytomer-based simulation model for growth in competitive weed-crop systems
Abstract
dc:descriptionA computer model for simulating the dynamics of vegetative phenology and vertical distribution of leaf area in competitive weed-crop systems was developed. The model was based on (1) a temperature function for leaf appearance rate (2) a function for individual leaf expansion based on leaf appearance (3) a function for elongation of individual internodes based on individual leaf expansion and (4) vertical stratification of leaf area based on the sum of subtending internode lengths. The degree day requirement for leaf appearance was determined for a number of crop and weed species. Leaf appearance in nearly all crops and weeds required more degree days in the field than in growth cabinets.
