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.

在自然条件下，植物会不断遇到各种生物和非生物因素，这可能会限制植物的生长和发育，甚至会限制作物的生产力。在影响植物光合作用的各种非生物因素中，光是驱动植物碳代谢和维持地球生命的重要因素。光的两个成分（光质量和光强度）极大地影响植物的光合作用和其他植物的形态，生理和生化参数。植物对不同光谱辐射和强度的响应在不同物种中也不同，并且还取决于生长条件。迄今为止，已经进行了许多有关强度不同的光谱辐射如何影响植物生长和发育的研究。
