27 lut 2023 · For leaf angle measurements, the triplet includes a point near the leaf collar (C), a point on the midrib (M), and a point on the stem (S). In this study, we aimed to identify the three keypoints with predefined relationships of a leaf angle in 2D images and reproject them into the 3D space to quantify the actual leaf angle.
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.
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:
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.
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.
15 sie 2023 · The leaf angle distribution refers to the probability of the leaf normal falling within a unit interval of inclination angle (Ross, 1981). Leaf inclination can also serve as an indicator of stress for some species (Biskup et al., 2007).
16 mar 2007 · Leaf angle distribution is one of the key parameters to simulate radiative transfer and energy and mass balance of vegetative canopies. Five leaf angle distributions functions have been proposed to account for the non-random distribution of leaf inclination angle.
