Experimental results of salinity effects on cucumber (Cucumis sativus, Cucurbitaceae) can be interpreted with the help of a functional-structural plant (FSP) model. Chen et al. use this novel approach to quantify...
Leaf N is generally highest in top leaves and decreases with depth in leaf canopies. Although such a gradient contributes to efficient use of canopy N for photosynthetic production, the gradient of leaf N is suboptimal...
