Abstract
5% PEG-6000 was used to produce the osmotic pressure,under which the effects of exogenous MeJA at three concentrations of 0.025,0.05 and 0.1 mmol·L-1 were measured on seed germination,seedling growth,oxidative damage to leaves,and protective enzyme activities in Brassica napus.The results indicated that the damages to B.napus caused by the osmotic stress of 5% PEG-6000 were significantly relieved in the presence of 0.1 mmol·L-1 MeJA.The seed germination rate,germination potentiality,germination index,and vigor index increased by 62.3%,11.2%,55.2% and 126.3%,respectively.The length of main root decreased by 45.0%,and the number of adventitious roots increased 59.4%,MDA content decreased by 20.6%.The protective enzyme activities of SOD,POD,CAT,and APX increased by 100.0%,109.1%,452.6%and 134.8% in leaves,respectively.Based on the data reported,we conclude that to some extent MeJA can alleviate inhibitory effect under osmotic stresses effectively and stimulates B.napus seed germination and seedling growth.MeJA can also enhance the activities of protective enzymes and relief oxidative damage.
