Effects of Plant Growth-promoting Bacterial on the Growth of Maize and the IAA Secrete Ability Detection
In this study,the test biocontrol bacteria were used to treat the maize seeds.Seven growthpromoting bacteria were selected through the detection of maize fresh weight,dry weight,height.Salkowski colorimetric solution was used for the IAA secrete ability detection of 7 test strains.The results showed a different levels increase of three agronomic traits which treated by 7 test strains;With the deal with Bacillus amyloliquefaciens strain C3,the maize fresh weight,dry weight,height were increased 185％,215％ and 66％,respectively;7 strains have a different IAA secrete ability;the B.amyloliquefaciens strain C3 has a higher IAA secrete ability than other 6 strains,251.37mg/mL.This is the first report of B.amyloliquefaciens used for maize growth-promoting in China.
