Multiscale Framework for Modeling and Analyzing Light Interception by Trees [PDF]

open access: yesMultiscale Modeling & Simulation, 2008
This paper presents a new framework for modeling light interception by isolated trees which makes it possible to analyze the influence of structural tree organization on light capture. The framework is based on a multiscale representation of the plant organization. Tree architecture is decomposed into a collection of components representing clusters of

LIGHT INTERCEPTION AND PRODUCTIVITY IN RICE

open access: yesMadras Agricultural Journal, 1992
A study was carried out to determine the relationship between light interception and productivity in rice. Cultivar difference could be observed in leaf area index, leaf angle, light extinction co-efficient (k), dry matter production grain yield.

Summary models for light interception and light-use efficiency of non-homogeneous canopies [PDF]

open access: yesTree Physiology, 2007
The application of detailed models of canopy photosynthesis rely on the estimation of attenuation of light in the canopy. This attenuation is readily estimated with the Lambert-Beer law when the canopy is homogeneous. In reality, forest canopies are far from homogeneous, and this has led to the use of detailed light extinction models that account for ...

THE EFFECTS OF NITROGEN NUTRITION ON LIGHT INTERCEPTION PARAMETERS

open access: yesActa Horticulturae, 2006
Parameters of light interception have an important role in plant growth and dry matter production. Those parameters are: leaf area index (LAI), cumulative interception (CI), light interception (I) and light use efficiency (LUE). The aim of the presented research was to investigate the effect of nitrogen nutrition on light interception parameters and ...

Modeling light-interception for a cotton population model

open access: yes, 1998
Light-interception by crops has been intensively studied since the early 1960s. Simple models of light interception for single plant, crop-rows, and for continuous canopy have been developed. More complex models, using crop geometry, have also been investigated and some of the studies tried to model plant competition.

Importance of the description of light interception in crop growth models. [PDF]

open access: yesPlant Physiol, 2021
AbstractCanopy light interception determines the amount of energy captured by a crop, and is thus critical to modeling crop growth and yield, and may substantially contribute to the prediction uncertainty of crop growth models (CGMs). We thus analyzed the canopy light interception models of the 26 wheat (Triticum aestivum) CGMs used by the Agricultural
