Corn was grown in rows between sloping concrete slabs painted either black or white. Grain yields were highest for the black concrete treatment. Transpiration was increased about 40% by the white concrete treatment.
With white surfaces, leaf temperatures were about 1 C higher and reflected radiation was five to six times greater compared to black surfaces. Corn leaves sampled adjacent to black concrete contained 40% more chlorophyll than corn leaves sampled adjacent to white concrete.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
