Modeling Photosynthesis of Row Crop Canopies

Direct solar radiation penetration into row crop canopies in a lean-to greenhouse

Experiments were conducted using model row crop canopies inside a model lean-to greenhouse (ratio 1 : 15) under artificial light to investigate the relations between row orientations and amount of direct solar radiation received by the canopy leaves. The model leaves were round in shape, horizontal in leaf inclination. The difference between the azimuthal directions of every two vertically neig...

Suboptimal Acclimation of Photosynthesis to Light in Wheat Canopies.

Photosynthetic acclimation (photoacclimation) is the process whereby leaves alter their morphology and/or biochemistry to optimize photosynthetic efficiency and productivity according to long-term changes in the light environment. The three-dimensional architecture of plant canopies imposes complex light dynamics, but the drivers for photoacclimation in such fluctuating environments are poorly ...

Effects of Crop Canopies on Rain Splash Detachment

Crops are one of the main factors affecting soil erosion in sloping fields. To determine the characteristics of splash erosion under crop canopies, corn, soybean, millet, and winter wheat were collected, and the relationship among splash erosion, rainfall intensity, and throughfall intensity under different crop canopies was analyzed through artificial rainfall experiments. The results showed t...

Modelling the Light Environment of Virtual Crop Canopies

Virtual plants describe functionally and geometrically plants as sets of interconnected organs. As many plant processes are driven by light, virtual plants require the estimation of the light absorbed by each organ. This has motivated the development of dedicated light models taking profit from the 3D geometry provided by virtual-plant models. We first introduce the principles governing the phy...
