29 wrz 2010 · In the first part of this review we will discuss the functional consequences of leaf orientation for plant performance. Next, we will consider hyponastic growth and describe how exploitation of natural (genetic) variation can be instrumental in studying the relevance and control of leaf positioning. Keywords:
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.
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.
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.
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.
15 sie 2023 · The leaf angle distribution refers to the probability of the leaf normal falling within a unit interval of inclination angle (Ross, 1981). Leaf inclination can also serve as an indicator of stress for some species ( Biskup et al., 2007 ).
The inclination of plant leaves refers to the angle between the normal line of the leaf surface and the zenith (z) axis. For flat leaves, it can also be defined as the angle between the leaf surface and the horizontal earth surface.
