3 paź 2024 · Leaf angle (LA), defined as the angle between the vertical stem and the midrib of a leaf blade, is a key agronomic trait affecting planting density and yield in maize [4], [5]. In maize, the LA depends on the ligular region, which links the distal blade to the basal sheath [6].
25 sty 2022 · 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.
20 kwi 2023 · New techniques to measure leaf angles are emerging, opening opportunities to understand the rarely-measured intraspecific, interspecific, seasonal and interannual variations of leaf angles and their implications to plant biology and earth system science.
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.
17 lip 2020 · Structural composition of leaf angle in rice and maize. Leaf angle is defined by the angle between the plant stem and leaf adaxial side of the blade, indicating as the α in the figure. This leaf morphology is affected by the development of ligule and auricle as well.
17 lip 2020 · Abscisic acid (ABA), CK, jasmonic acid (JA), and strigolactones (SLs) negatively regulate BR, thereby inhibiting leaf angle, whereas gibberellins (GA) positively coordinates BR to increase leaf angle. Application of auxin results in erect leaf while ethylene leads to flat leaf.
25 mar 2015 · The leaf angle (LA) was scored as the angle of each leaf from a plane defined by the stalk below the node subtending the leaf. The leaf length (LL) was measured as the length from the base of the ligula to tip of the leaf.
