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.
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.
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.
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...
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.
29 wrz 2023 · The leaf angle genetic gain (toward more erect leaves) was on average 0.08% year −1 for the middle canopy leaves and eightfold larger for the flag leaf. Our results revealed a synergistic effect with similar contributions of maize breeding and plant density on historical leaf angle changes in the middle canopy.
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.
