Interactions between Diffuse Light and Cucumber (<i>Cucumis sativus</i> L.) Canopy Structure, Simulations of Light Interception in Virtual Canopies
Plant photosynthesis and biomass production are associated with the amount of intercepted light, especially the light distribution inside the canopy. Three virtual canopies (n = 80, 3.25 plants/m<sup>2</sup>) were constructed based on average leaf size of the digitized plant structures:...

| description | Plant photosynthesis and biomass production are associated with the amount of intercepted light, especially the light distribution inside the canopy. Three virtual canopies (n = 80, 3.25 plants/m<sup>2</sup>) were constructed based on average leaf size of the digitized plant structures: ‘small leaf’ (98.1 cm<sup>2</sup>), ‘medium leaf’ (163.0 cm<sup>2</sup>) and ‘big leaf’ (241.6 cm<sup>2</sup>). The ratios of diffuse light were set in three gradients (27.8%, 48.7%, 89.6%). The simulations of light interception were conducted under different ratios of diffuse light, before and after the normalization of incident radiation. With 226.1% more diffuse light, the result of light interception could increase by 34.4%. However, the 56.8% of reduced radiation caused by the increased proportion of diffuse light inhibited the advantage of diffuse light in terms of a 26.8% reduction in light interception. The big-leaf canopy had more mutual shading effects, but its larger leaf area intercepted 56.2% more light than the small-leaf canopy under the same light conditions. The small-leaf canopy showed higher efficiency in light penetration and higher light interception per unit of leaf area. The study implied the 3D structural model, an effective tool for quantitative analysis of the interaction between light and plant canopy structure. |
