Shade cloth can be used to protect grapevines from high temperatures. However, the resulting low light intensity is shown to reduce photosynthesis, leading to lower carbon allocation to vegetative growth and sugar accumulation. Protection from heat by shading is, therefore, costly for the carbon economy of the vines. Read this free — open access paper to find out more.
