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.
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.
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.
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.
C, Leaf angle changes between W22 and beh1-1 plants at the V2 and V10 stages. The leaf angles of the second and sixth leaves were measured at the V2 and V10 stages, respectively. n = 20. D, Quantitative measurement of auricles in W22 and beh1-1 plants at the V2 stage. Twenty replicates were used for auricle margin width and area.
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.
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.
