Tobacco treated with NaSH

Hydrogen sulfide (H2S) is a new endogenous gas signaling molecule alongside nitric oxide (NO) and carbon monoxide (CO). In recent years, many studies have shown that it is involved in a variety of physiological activities, promoting root organogenesis, regulating stomatal movement and photosynthesis, and playing an important role in promoting plant growth and development and improving the stress resistance of the plant Plants can play. Tobacco is a special and an important cash crop whose growth usually determines the economic income of farmers. Tobacco root development directly affects leaf growth, disease resistance, chemical composition and yield. However, to date, there are limited studies on the mechanism of H2S in promoting tobacco growth.
