摘要:

在自然条件下,植物经常遭受各种生物和非生物因素胁迫而影响其生长和发育,特别是限制作物的生产能力。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,而光环境中光强和光质的变化极大地影响植物的光合作用以及其形态,生理和生化参数,且不同植物对光强和光质的响应不同,与其生长的环境条件有关。目前,大量研究报道了光照强度是如何影响作物的生长和发育,而本综述归纳总结了光环境中不同光质成分和光强对作物的叶片形态和解剖结构,气孔发育,光合作用,色素组成,活性氧,抗氧化酶和激素动态等相关参数的影响,旨在为作物光合作用对光强和光质的响应机制研究提供理论支撑。


Abstract:

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.
