种衣剂添加黑曲霉对盐胁迫下玉米苗期生长的影响
Effect of Adding Aspergillus niger to Seed Coating Agent on Seedling Growth of Maize Under Salt Stress
摘要
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.关键词
