光照强度对药用植物生长及药用品质影响的研究进展OA

Light intensity is a pivotal environmental factor regulating the growth,development,and the synthesis and accumulation of secondary metabolites in medicinal plants,directly influencing the yield and quality of the medicinal materials.Light intensity profoundly shapes the phenotype and chemotype of medicinal plants by affecting photomorphogenesis,photosynthetic efficiency,the allocation of carbon and nitrogen metabolic flux,and the expression of genes in key metabolic pathways.Appropriate control of light intensity is an effective strategy to enhance both the economic yield and the content of bioactive compounds.However,significant variations exist among different species,and even in different medicinal parts of the same species,regarding their demands for light intensity.This paper systematically reviewed recent research advances on the effects of varying light intensities on the morphological development,photosynthetic parameters,accumulation of secondary metabolites,and gene expression and genomic responses of medicinal plants,aiming to provide a reference for the precision cultivation and high-quality production of medicinal plants.
