Use of 3D modeling to refine predictions of canopy light utilization: A comparative study on canopy photosynthesis models with different dimensions

open access: yesFrontiers in Plant Science, 2022
Canopy photosynthesis integrates leaf functional and structural traits in space and time and correlates positively with yield formation. Many models with different levels of architectural details ranging from zero-dimensional (0D) to three-dimensional ...

Optimizing trade-offs between light transmittance and intraspecific competition under varying crop layouts in a maize–soybean strip relay cropping system

open access: yesCrop Journal
Light is one of the most important environmental factors for plant growth and development. In relay cropping systems, crop layouts influence light distribution, affecting light use efficiency (LUE).

Determination of the Velocities of Projectiles by the Method of Light Interception [PDF]

open access: yesNature, 1931
MESSRS. Payman and Woodhead appear to have misunderstood the method described in our letter in NATURE of Dec. 27, p. 994. We made no claim to originality of application of the principle of light interception. Our method does not depend on shadow or ordinary photography, which has been used in ballistics since the time when Boys took his first shadow ...

Light interception and radiation use efficiency of cotton [PDF]

open access: yes, 2021
Η συσσώρευση ξηράς ουσίας από μια καλλιέργεια είναι μια άμεση συνάρτηση της ποσότητας της ακτινοβολίας που αναχαιτίζεται από την φυλλική επιφάνεια. Η αποτελεσματικότητα μιας καλλιέργειας να μετατρέπει την αναχαιτισμένη ακτινοβολία σε ξηρή μάζα ονομάζεται αποδοτικότητα χρήσης ακτινοβολίας.

Sweet Pepper (Capsicum annuum L.) Canopy Photosynthesis Modeling using 3D Plant Architecture and Light Ray-tracing

open access: yesFrontiers in Plant Science, 2016
Canopy photosynthesis has typically been estimated using mathematical models that have the following assumptions: the light interception inside the canopy exponentially declines with the canopy depth, and the photosynthetic capacity is affected by light ...

Understory plants evade shading in a temperate deciduous forest amid climate variability by shifting phenology in synchrony with canopy trees.

open access: yesPLoS ONE
Global warming is leading understory and canopy plant communities of temperate deciduous forests to grow leaves earlier in spring and drop them later in autumn.

Ecophysiological Management Using Light Interception Technology with the AccuPar Equipment: Quality Versus Quantity of Forage

open access: yesAgriEngineering
Background: Understanding canopy light interception is essential for optimizing forage production and improving the efficiency of grazing systems. Accurate quantification of photosynthetically active radiation (PAR) intercepted by the canopy allows for ...

Light interception and evapotranspiration in hedgerow agroforestry systems

open access: yesAgricultural and Forest Meteorology, 1996
Abstract Quantifying water lost through evaporation and transpiration in a cropping system is an important tool in adapting a system for semi-arid conditions. During two cropping seasons in eastern Kenya, light interception and soil water content were measured in several different cropping systems: monocultures of cowpea ( Vigna unguiculata (L ...
