    Abstract

    At high irradiation levels, diffuse greenhouse coverings result in better light distribution, lower crop temperature, decreased transpiration, and increased photosynthesis and growth. Various greenhouse coverings (plastic films, glass panes and temporal coatings) can be used to transform direct light into diffuse light. However, light diffusing properties of materials are hardly known. Optical properties of a wide range of materials are being currently investigated, including direct light transmission under different angles of incidence, transmission for hemispherical light and haze. The potential of diffusing greenhouse covering materials is estimated by analyzing the global radiation data for different climatic regions: marine winter climate (The Netherlands), Mediterranean mild winter climate (Italy) and semi-arid climate (Arizona). The required optical properties differ for the various climates. With modern material technology, the optical properties (haze and light transmission) can be altered to meet the requirements for different climatic regions in order to optimize crop performance in the future.
