EFFECTS OF PLANT GROWTH REGULATORS ON PHOTOSYNTHESIS AND PHYSIOLOGICAL CHARACTERISTICS OF CROPS

ABSTRACT

In recent years, with the continuous development of agricultural production, people's demand for how to improve crop yield and quality is getting higher and higher. As an important technical means of agricultural production, plant growth regulators have been widely used in crop growth management. In this paper, the effects of plant growth regulators on photosynthetic and physiological characteristics of crops were studied, and their regulatory effects on photosynthetic rate, chlorophyll content, photosynthetic related enzyme activity, gene ex pression, growth rate, canopy structure, root morphology, resistance to reverse and disease resistance were discussed. At the same time, according to the research content, the relevant research methods and experimental design were proposed, including the selection of suitable crops and growth regulators, the design of control group and experimental group, and the measurement of photosynthesis and physiological indexes. Finally, combined with the research results and discussion, the influencing factors and mechanisms of different plant growth regulators on the photosynthetic and physiological characteristics of crops were analyzed, and the application prospects of plant growth regulators in agricultural production and the potential of improving crop yield and quality were prospeced, and theoretical and technical support was provided for agricultural production. By studying the effects of plant growth regulators on photosynthesis and physiological characteristics of crops, we can provide more scientific and rational management and regulation strategies for agricultural production, and further promote the sustainable development of agriculture.
