Abstract

Abstract: ： Hydroponic methods were used to set five different potassium supply levels of 0.32,0.22,0.12,0.02,and 0.00 g/L to study the response of defensive enzymes of peacockgrass （Tagetes patula L.） to low potassium stress. The results showed that with the gradual decrease of potassium concentration, the activities of POD, SOD, and CAT of peacockgrass increased gradually; MDA content increased sharply; root plasma membrane permeability increased with decreasing potassium concentration. It was concluded that the defense enzyme activity of peacockgrass gradually increased under low potassium stress.

Key words: peacockgrass （Tagetes patula L.）, low patassium stress, defensive enzymes, root plasma membrane permeability
