Abstract: In this paper,the noise frequency of 2－ 4kHz and intensity of 90dB was selected to treat post harvest tomatoes in order to study the changes of physiology and biochemistry parameters in 8 days storage time.The results obyained showed that the noise treatment could remarkably develop the brething intensity,make their respiration peak ahead and make the speed of the consume of the carbohydrate accelerated,increase the ethylene production and make mature period ahead,promote the activities of ascorbic oxidative enzyme and CAT and make tomatoes doddery and damage cells and lead to the cell membrane osmotic rate increased,as compared with the tomatoes control not treated by noise.
