註釋Light distribution in canopies is important for crop photosynthesis, growth and yield. In this thesis variability in light absorption and photosynthesis within tomato canopies was explored with a 3D model assisted analysis. There were four main findings. Firstly, due to plant acclimation, row orientation had a minimal influence on canopy light absorption and net photosynthesis. Secondly, including interplant variation in architectural and photosynthesis parameters is a cumbersome effort which does not have a large impact on simulated averages of a canopy. Thirdly, locally supplied far-red light has long-distance effects on length, dry weight of the stem and on specific leaf area. This is a clear indicator that future studies on light spectrum should look into the integration of light spectrum perceived on different heights of the plant. Fourthly, leaflets in intra-canopy lighting generally have a more uniform overall light absorption.
