Abstract:: The effects of simulated acid rain with different pH on the germination rate，germination energy，germination indexes，vigor index and root-electrical conductivity of seed of Brassica juncea var. tsatasi Mao were conducted．The results showed that each physiological indexes of seed germination gradually reduced and the electrical conductivity of liquid of soaking root increased with the decrease of pH value；under the condition of simulated acid rain with different pH，seed germination rate of Brassica juncea var. tsatasi Mao was affected much less，but the fresh weight and vigor index were influenced largely.So the effect of simulated acid rain on the seed germination of Brassica juncea var. tsatasi Mao was significantly.
