20 kwi 2023 · Leaf angle plays a similar role as stomates at the leaf level: By adjusting stomatal conductance, a balance between carbon gain and water loss is achieved; by adjusting leaf angle, the plant canopy can achieve optimized carbon gain while reducing heat stress and water loss.
2 paź 2024 · We show that leaf angle dynamics systematically confound widely applied vegetation indices. Moreover, we demonstrate that these effects are not random but tightly linked to abiotic...
16 mar 2007 · Leaf angle distribution is one of the key parameters to simulate radiative transfer and energy and mass balance of vegetative canopies. Five leaf angle distributions functions have been proposed to account for the non-random distribution of leaf inclination angle.
The leaf angle distribution (or LAD) of a plant canopy refers to the mathematical description of the angular orientation of the leaves in the vegetation. Specifically, if each leaf is conceptually represented by a small flat plate, its orientation can be described with the zenith and the azimuth angles of the surface normal to that plate.
26 lut 2015 · A mathematical equivalent for leaf orientation is the leaf angle or leaf angle distribution. Our methods and algorithms are designed for the local derivation of leaf angles on the base of individual leaf models.
15 sie 2023 · Leaf angle distribution (LAD) is an important plant structural trait that determines radiation interception, biomass production, rainfall interception, and evapotranspiration. LAD has remained one of the most poorly constrained parameters and a major source of uncertainty in ecological models due to difficulty in quantification.
15 sty 2019 · Leaf angle distribution (LAD) is an important property which influences the spectral reflectance and radiation transmission properties of vegetation canopies, and hence interception, absorption and photosynthesis. It is a fundamental parameter of radiative transfer models of vegetation at all scales.
