Review on Effects of Light and Nitrogen Interaction on Plant Growth and Nitrogen Metabolism
Light and nitrogen are the key factors affecting plant growth and development.Plant photosynthesis depends on energy provided by light,and light intensity and light quality play an important role in plant growth,physiology,biochemistry and nitrogen metabolism.Fertilizer provides the necessary nutrients for plant growth,especially nitrogen fertilizer.The levels of nitrogen supply also affect the physiological characteristics of plants.Moreover,nitrogen is essential for the synthesis of enzymes and their cogroups involved in regulating plant biochemical reactions.However,plant growth and development are often co-regulated by multiple environmental factors.The interaction of light and nitrogen fertilizer is suggested having a significant impact on plants.This paper reviewed the effects of light,nitrogen and light-nitrogen interaction on indicators of plant growth and development,and expounded the importance of light and nitrogen interaction.It is beneficial for further understanding the interaction among various factors affecting plant growth,and provides a theoretical basis for better improving the production efficiency and quality of plants,especially crops.
