Abstract：To investigate the effect of adding Aspergillus niger to the seed coating agent on the growth of corn seedlings under salt stress,six treatments were set up in the experiment:control group(CK),salt stress control group(NCK),application of seed coating agent under salt stress(NHQ),application of seed coating agent under salt-free stress(HQ),application of seed coating agent with addition of Aspergillus niger under salt stress(NHQ-A),application of seed coating agent with addition of Aspergillus niger under salt-free stress(HQ-A).The results showed that compared with NHQ and HQ,the root length and leaf width of NHQ-A and HQ-A groups increased by 16.07％,30.06％and 11.08％,6.88％,respectively.Chlorophyll SPAD,superoxide dismutase(SOD),peroxidase(POD)and catalase(CAT)activity increased significantly,while malondialdehyde(MDA)content decreased.This study demonstrates that the addition of Aspergillus niger to seed coating agent has a certain promoting effect on the growth of maize seedlings,and can alleviate some of the harm caused by salt stress on maize.
