Abstract: The heat shock treatment was conducted on the seeds of two cabbage(Brassica oleracea L) varieties with different heat-resistant ability,and the activity of leaf protect enzymes and membrane permeability were tested in seedling stage.The results showed that,after heat shock treatment,the activity of SOD,CAT,and POD in the leaves of heat-resistant variety had a higher increase than in the heat-sensitive variety;and the increase of MDA and membrane permeability was higher in the heat-sensitive variety than in the heat-resistant variety.

Key words: Cabbage, Heat shock treatment, Protection enzyme, MDA, Membrane permeability
