20 kwi 2023 · We review the role of leaf angle in studies of ecophysiology, ecosystem ecology and earth system science, and highlight the essential yet understudied role of leaf angle as an ecological strategy to regulate plant carbon–water–energy nexus and to bridge leaf, canopy and earth system processes.
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.
Introduction. Flat leaves obscure the sky when one looks up towards the zenith. Towards the horizon, however, they let light come through. The contrary applies to erect leaves. The inclination angle of the leaves therefore affect the appearance of the canopy on the hemispherical photograph.
Abstract: Leaf angle distribution (LAD) is an important attribute of forest canopy architecture and affects the solar radiation regime within the canopy. Terrestrial laser scanning (TLS) has been increasingly used in LAD estimation.
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.
10 cze 2021 · Here, we present TLSL e AF (Terrestrial Laser Scanning Leaf Angle Function), an automated open-source method of deriving LADs from terrestrial laser scanning. TLSL e AF produces canopy-scale leaf angle and LADs by relying on gridded laser scanning data.
6 lis 2017 · Leaf angle, defined as the inclination between the leaf blade midrib and the stem, is one of the most important canopy architecture parameters that influence light interception, photosynthetic efficiency, and planting density.
