The Catalase（CAT）, Peroxidase（POD）, Superoxide dismutase（SOD）, Polyphenol oxidase（PPO）and Phenylalnine ammonialyase（PAL）activity, the Superoxide anion free radical（O-2）generation rate, the Hydrogen peroxide（H2O2）, Salicylic acid and Lignin content of mung bean germinations were detected, which were subjected to different centrifugal intensity (acceleration), such as reversible damage(94g）, slight damage(376g）, moderate damage(845g）, serious damage(1503g）, and breakage damage(3381g）. One gravitational acceleration （g）=9.8m/s2. The results showed that the disease resistance would be induced by all the centrifugal damages including reversible damage in the early stage. The content of free Salicylic acid（SA） and H2O2, POD activity were significantly increased by reversible damage while the change of the O-2 generation rate, total hydroxybenzene, lignin content, the SOD, CAT, PAL and PPO activity were indistinctive. The significant changes of more disease resistance indicators were caused by slight damage, moderate damage and serious damage. Especially the POD activity was increased remarkably under slight damage and moderate damage. The content of free SA, H2O2, total hydroxybenzene and lignin rose in the maximum while the O-2 generation rate, the CAT, PAL and PPO activity declined in the maximum when it was treated with breakage damage. Besides, the SOD activity was not sensitive to all the damages. 
