Foliar application of 24-epibrassinolide enhances leaf nicotine content under low temperature conditions during the mature stage of flue-cured tobacco by regulating cold stress tolerance

Abstract Background Low temperatures disrupt nitrogen metabolism in tobacco, resulting in lower nicotine content in the leaves. 24-epibrassinolide (EBR) is a widely used plant growth regulator known for its roles in enhancing cold tolerance and nitrogen metabolism. Nevertheless, it remains unclear w...
