- Leaf angle, the angle between the leaf normal and the zenith (Figure 1, Box 1), is a key leaf trait associated with light interception, photosynthesis, energy balance and competition among individual plants (Anten, 2005; Nilsen & Forseth, 2018; Ross, 1980).
Apr 20, 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.

How does leaf angle affect K?
In monocots, leaf angle or lamina inclination is the degree of bending between the leaf blade and leaf sheath. Appropriate leaf angles allow higher light capture of the whole plants, which enables plantings with high density to increase leaf area index (Sinclair and Sheehy, 1999 ).
Aug 16, 2019 · Plant architecture with more upright leaves (i.e., smaller leaf angle) decreases mutual shading and sustains light capture for photosynthesis despite increased plant density, thus improving the accumulation of leaf nitrogen for grain filling and increasing grain yield (2–5).

The leaf angle is a major factor governing k in a given species. Leaf surface properties affecting reflection, leaf properties including thickness, leaf size and shape, and characteristics affecting the three-dimensional arrangement of leaves also affect k (Hay and Porter, 2006).

Jan 25, 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.
Feb 12, 2017 · In plants, the leaf angle (LA) affects how densely crops can be planted and thus is one of factors determining grain yield per acre. This complex quantitative trait is controlled by developmental signals, hormones, and environmental factors (Luo et al., 2016).
Dec 16, 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.
