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.
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.
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.
Here, we present TLSLeAF (Terrestrial Laser Scanning Leaf Angle 31 Function) – an automated open-source method of deriving leaf angle distributions from 32 terrestrial laser scanning. 33 TLSLeAF produces canopy-scale leaf angle and LADs by relying on gridded laser 34 scanning data.
20 kwi 2023 · Diagram of leaf and solar angles. θl is the leaf inclination angle from horizontal, equivalent to the angle between the leaf normal and the zenith (the green arrow is the leaf normal); θs is...
6 paź 2022 · To be clear, the leaf surface angles do not inform if the leaves are pointing upward or downward (axis from leaf petiole to tip) but represent the integrated angle of the leaf surface. An increase in leaf angles can, hence, result from a downward tilt of the leaves.
