Abstract
The solar radiation received at the Earth’s surface helps power the photochemical processes in photosynthesis. However, under sunlight, photosynthetic organisms are unavoidably exposed to potentially harmful levels of ultraviolet and visible light radiation. Consequently, plants have developed many mechanisms for the avoidance and dissipation of excess light energy. The growth of crops under increased solar irradiance during sub- and supra-optimal temperature conditions is an obstacle for increasing seasonal crop production in the transition zone. New methods for reducing the photoinhibitory effects of solar irradiation have been observed in the field of turfgrass. Through the application of pigment compounds to the surface of plant leaves, it may be possible to reduce levels of solar incident light exposure to the plant, during temperatures where the fixation of CO2 is a limiting factor in Photosystem II repair.
