3 paź 2024 · Abstract. 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.
6 paź 2022 · Leaf angle predictions were evaluated over a wide range of species and scene conditions using independent samples from visual interpretation ( R ² = 0.84) and compared to leaf angle...
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.
Leaf angle (LA) is a key trait of plant architecture and a target for genetic improvement of crops. Upright leaves allow better light capture in canopy under high-density planting, thus enhancing photosynthesis efficiency, ventilation and stress resistance, and ultimately higher grain yield.
15 sie 2023 · In this short communication, we explore the potential of machine learning to remove the current bottleneck (manual operation/leaf identification) in estimating leaf angle distribution type, which does not require the acquisition of expensive equipment (e.g. terrestrial laser scanner).
6 paź 2022 · Leaf angle predictions were evaluated over a wide range of species and scene conditions using independent samples from visual interpretation (R2 = 0.84) and compared to leaf angle estimates obtained from terrestrial laser scanning (R2 = 0.75).
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.
