Abstract

During the past decade important advances have been made in the measurement of light and radiant energy. Although previous to this time emphasis was placed on the refinement of instruments for measuring light, during this period emphasis has been placed on the measurement of radiant energy since plants are affected by rays both longer and shorter than those of the visible spectrum.
