摘要
光对光合作用和植物生长至关重要。光对植物生长发育的影响是复杂的;光对植物的整体影响并不是有益的。除光合作用外，光还控制着开花时间和形态发生。两种主要的光感受器——光敏色素(吸收远红光)和隐光色素(吸收蓝光/紫外线)负责植物形态和发育变化(Quai et.al,1995 and Deng et.al, 1999)。最佳照明制度有可能提高产量，改善植物质量，营养价值和风味。除了提高植物的健康和质量外，由于植物抗性的提高以及害虫/病原体生物学的直接破坏，害虫和病原体的影响可以减少(Pearson et al. 2015)。
Review on Effect of Light on Disease Development and Management of Horticultural Crops under Protected Cultivations
Light is crucial for photosynthesis and plant growth. The effects of light on plant growth anddevelopmentarecomplex;theentirespectrumoflightisnotbeneficialforplants.Livingorganismsgeneral lyharvestthevisibleelectromagneticspectrum,Apartfromphotosynthesis,lightalsocontrolsfloweringtime andmorphogenesis.Twomajorphotoreceptors-phytochromes(absorbsred/far-red-light)and crypto chromes (absorbsblue/ultravioletA(UV-A) light) are responsible for plant morphological and developmental changes(Quai et.al,1995 and Deng et.al, 1999 ).Optimal lighting regimes have the potential to increase yields and improve plant quality, nutritional value, and flavor. In addition to enhancement of plant health and quality, the impacts of pests and pathogens can be reduced both as a result of elevated plant resistance and also by direct disruption of pest/pathogen biology (Pearson et al. 2015).
