Abstract
The effects of methyl jasmonnate(MeJA)at 4 concentrations,i.e.0.0(CK),0.2,0.5,1 mmol.L-1 on banana cold tolerance and relevant physiological changes in banana seedlings(Musa AAA Cavendish)were studied.Results showed that MeJA treatment significantly increased POD activities and concentrations of soluble sugars and proline,but decreased membrane leakage and O2 production rate in the leaves in low temperature.As a result,the cold tolerance of banana seedlings was improved by MeJA treatment.Among all the treatments,the optimum MeJA concentration for improving banana cold-tolerance was shown to be 0.2 mmol.L-1.
