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...
15 sie 2022 · Leaf angles (i.e., leaf inclination relative to the horizontal) were collected for a large number of leaves from both sunlit and shaded crowns using ladders, mobile elevators, scaffolding towers or cameras mounted on UAVs for canopy access.
20 kwi 2023 · Leaf angle, the angle between the leaf normal and the zenith (Figure 1, Box 1), is a key leaf trait associated with light interception, photosynthesis, energy balance and competition among individual plants (Anten, 2005; Nilsen & Forseth, 2018; Ross, 1980).
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.
6 lis 2017 · Leaf angle is defined as the inclination between the midrib of the leaf blade and the vertical stem of a plant. This trait has been identified as a key component in the development of high-yielding varieties of cereal species, particularly maize, rice, wheat, and sorghum.
20 lut 2019 · In this letter, we propose an efficient and low-cost approach to estimate both leaf zenith and azimuth angles from smartphone photographs by using a structure from motion (SfM) point cloud and...
25 paź 2022 · Leaf angle distribution (LAD) is an important factor for characterizing the optical features of vegetation canopies. The characterization of LAD requires direct measurements of leaf inclination...
