Abstract: The effects of spraying different concentrations of Coronatine on the growth and photosynthetic characteristics of flue-cured tobacco were studied. The results showed that spraying Coronatine had significant bidirectional influences on the net photosynthetic rate,stomatal conductance,intercellular CO2concentration and transpiration rate of tobacco leaves,namely low concentration of Coronatine inhibited the growth of tobacco,while high concentration of Coronatine promoted the growth of tobacco. Spraying 0. 1 mL / L or 0. 05 mL / L Coronatine had promotive effects on the photosynthetic characteristics and agronomic traits of tobacco, while all indexes of tobacco in the treatment of spraying 0. 01 mL / L Coronatine were lower than those in the control group. Coronatine concentration 0. 1 mL / L was more suitable for the growth of tobacco,and spraying 0. 1 mL / L Coronatine could furthest increase the quality,yield and economic benefits of tobacco.
