Coronatine(COR) is one kind of phytotoxin,secreted by Pseudomonas syringae and is similar to the structure of JA,and could induce the plant resistance with the low concentration.The inductive effects on drought resistance of spraying different COR concentrations was studied using two winter wheat cultivars Jimai 22 and Liangxi 99 as experimental materials in a hydroponic experiment.The results shows that,in the condition of 20% PEG-6000 simulated water stress,spraying lower concentration of COR solution(≤1 ...
