15 paź 2022 · Leaf angle distribution (LAD) is an essential canopy element that controls the foliage projection function (G-function), which is a parameter for estimating the plant area index (PAI). In recent studies, digital cover photography (DCP) has been applied to estimate the PAI (PAI DCP) in many terrestrial ecosystems.
16 mar 2007 · The aims of this paper are to, (1) quantitatively compare the performance of leaf angle distribution functions to describe the empirical leaf angle distributions and find an appropriate function for the retrieval of leaf angle distribution with remotely-sensed data; (2) estimate the effects of leaf angle distribution functions on extinction ...
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).
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 kwi 2023 · Using two models, we show that leaf angle variations have significant impacts on not only canopy-scale photosynthesis, energy balance and water use efficiency but also light competition within the forest canopy.
15 lut 2013 · We found that reliable estimates of leaf angle distributions at the level of a whole tree can be obtained by measuring the leaf inclination angles of 75 leaves distributed across the vertical tree profile using a simple technique based on digital photography.
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...
