3 paź 2024 · In grain crops such as maize (Zea mays), leaf angle (LA) is a key agronomic trait affecting light interception and thus planting density and yield. Nitrogen (N) affects LA in plants, but we lack a good understanding of how N regulates LA.
1 wrz 2020 · A MATLAB-based image processing framework, Leaf Angle eXtractor (LAX), was developed to extract and quantify leaf angles from images of maize and sorghum plants under drought conditions....
6 paź 2022 · We applied TLSLeAF with a spatial sub-sampling of the point cloud of 0.005 m, an upper limit of the scattering angle of 80° (angle between leaf surface normal and beam direction), spatial scales of the leaf-wood classifier of 0.1, 0.5, 0.75 and without topography correction.
6 lis 2017 · Leaf angle, defined as the inclination between the leaf blade midrib and the stem, is one of the most important canopy architecture parameters that influence light interception, photosynthetic efficiency, and planting density.
26 lut 2015 · Our approach includes a semi-automatic selection process of single leaves and different modes of surface characterization via polygon smoothing or surface model fitting. Based on the resulting surface meshes leaf angle statistics are computed on the whole-leaf level or from local derivations.
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.
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:
