Abstract
Weight method was used to investigate the effect of coronatine on photosynthesis parameters and endogenous hormone contents in maize (Zea mays) seedling under drought stress. The results showed that application of coronatine increased significantly diameter of basal stem, root length, seedling weight, photosyn- thesis rate (Pn), transpiration rate (Ts) and stomatal conductance (Gs). And it decreased significantly intercellular CO2 concentration (Ci) in leaf and significantly increased ABA and 1-aminocyclopropane-1-carboxylic acid (ACC) contents in maize seedling. The increased drought resistance of maize seedlings after coronatine treat- ment might be involved ABA/GA3 in leaf and root.
