FIGURE 2.

An illustration of three canopy architectures, two of which have been suggested to improve drought tolerance in potato: open “stem-type” canopies, e.g., cv. Tomba, which may improve light penetrance and interception (middle), and very small canopies, e.g., cv. Alpha, which may reduce evapotranspirative water loss (right). A dense “leaf-type” canopy, e.g., cv. Procudent, which has been suggested to be detrimental to potato yields under drought is also illustrated (left).
