Screening the Resistance Resources of Rhizobium japonicum Based on GGE-biplot
In order to evaluate the stability and adaptability of Rhizobium japonicum in drought and acid base environment,analysis the ability of 7 Rhizobiumjaponicur strains on drought,acid and alkali resistance through GGE-Biplot,the strains were separated,identified and purified from different ecological area in Heilongjiang province.The results showed that the growth of the strain gradually decreased with the increase of PEG6000 concentration.GGE-Biplot showed that 111-1 was with strong drought resistance and better stability.The tested strains had great advantage in acid alkali resistance,can grow slowly when pH3.0 and pHll2.0,and have the most growth increment when pH9.O.GGE-Biplot also showed that 112-2 was with high acid resistance and good stability,as the mean while,111-3 was with high alkali resistance and good stability.The results are of important meaning to the application of Rhizobium japonicum in different environmental conditions in Heilongjiang province.
