Effect of exogenous methyl jasmonate on induced resistance of Eucalyptus grandis seedlings against Leptocybe invasa
摘要
Abstract
In order to explicate the effect of exogenous methyl jasmonate ( MeJA ) on activities of related defense enzyme and induced resistance of Eucalyptus grandis seedlings against Leptocybe invasa Fisher et La Salle, effects on the activities of related defense enzymes and protease inhibitors such as phenylalanine ammonialyase (PAL), superoxide dismutase (SOD), peroxidase (POD), polyphemol oxidase (PPO), trypsin inhibitors (TI) and chymotrypsin inhibitors (CI) were analyzed by treating with MeJA at different concentrations. The effects of MeJA on the index of population trend and control effect of L. invasa were also measured. The results showed that after 24-148 h, the activities of PAL, SOD, POD, PPO, TI and CI changed in varying degrees. MeJA at 1.00 mmol·L-1 had obvious control effect of L. invasa with 70.98% and the index of population trend reached 24.13. These results indicated that MeJA induced E. grandis resistance against L. invasa which related to the increased activities of defense enzymes and protease inhibitors caused by MeJA.关键词
