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.
16 gru 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.
15 lut 2013 · Abstract. Angular distribution of leaves is an important parameter determining the transmission and reflection of radiation by vegetation canopies. When inverting canopy transmittance measurements for estimating the leaf area index or canopy clumping, incorrect assumptions on leaf angles may lead to considerable errors.
The leaf angle is a major factor governing k in a given species. Leaf surface properties affecting reflection, leaf properties including thickness, leaf size and shape, and characteristics affecting the three-dimensional arrangement of leaves also affect k (Hay and Porter, 2006).
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.
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.
