Abstract:
In order to make clear the endurance abilities and the biocontrol potential of soybean rhizobia resourse of Liaoning province.The growth or survival abilities of soybean rhizobia strains isolated from different area were tested under the stresses of acid，alkali，NaCl，(NH-4)2SO4，high temperature，low temperature，and their potential to control soybean root pathogens was researched.Soil samples were collected from different geographical area in Liaoning province and soybean root nodules were trapped from the soil sample；16 strains of soybean rhizobia were isolated by tissue isolation.The results showed that the stress-tolerant capability and antagonistic effect of the 16 rhizobia strains differ greatly.Stains Snb119，Snb126，Snb183 can grow under the stresses of acid，alkali，NaCl，(NH4)2SO4，high temperature，low temperature.Snb183，strains Snb204，Snb389，Snb394 inhibit growth of Pythium.spp，Snb183，Snb241 strains suppress J2 of soybean cyst nematode.
