Exogenous Brassinolide (BL) Mitigates Drought Stress in Salvia miltiorrhiza: A Study on Physiological and Growth Responses

This investigation aims to analyze the modifications in physiological reactions and growth characteristics induced by exogenous BL under drought stress conditions. This study encompasses the analysis of antioxidant enzymes, osmotic regulators, photosynthetic pigments, photosynthesis, and plant growth. The data derived from this study will provide insights into the influence of exogenous plant hormone BL on the response to drought stress in S. miltiorrhiza, advancing our understanding of how BL can enhance drought tolerance in this medicinal plant.
