Under natural conditions, plants constantly encounter various biotic and abiotic factors, which can potentially restrict plant growth and development and even limit crop productivity.  Among various abiotic factors affecting plant photosynthesis, light serves as an important factor that drives carbon metabolism in plants and supports life on earth.  The two components of light (light quality and light intensity) greatly affect plant photosynthesis and other plant’s morphological, physiological and biochemical parameters.  The response of plants to different spectral radiations and intensities differs in various species and also depends on growing conditions.  To date, much research has been conducted regarding how different spectral radiations of varying intensity can affect plant growth and development.  This review is an effort to briefly summarize the available information on the effects of light components on various plant parameters such as stem and leaf morphology and anatomy, stomatal development, photosynthetic apparatus, pigment composition, reactive oxygen species (ROS) production, antioxidants, and hormone production.
Keywords:  light intensity        light quality        photosynthesis       , stomatal development        pigment composition        reactive oxygen species        antioxidants       plant hormones
