Study on the mechanism of nano-selenium alleviating high salt stress in rapeseed
This study examined the effects of various treatments on the root length,plant height,biomass,chlorophyll content,reactive oxygen species,and CAT enzyme activity of rapeseed when selenium source and nano-selenium with different salt concentrations were used as test objects..The results indicate that the application of selenium has a promoting effect on the phys-iological growth of rapeseed under high salt stress,significantly enhancing the root length,plant height,and biomass of rapeseed.The application of nano-selenium has a more pronounced promoting effect on the physiological growth of rapeseed.The con-tent of reactive oxygen species in the selenium-containing group is significantly lower than that in the selenium-free group,in-dicating that selenium has a role in scavenging reactive oxygen species.The content of CAT enzyme in the selenium-containing group is higher than that in the selenium-free group,indicating that selenium can enhance the activity of CAT enzyme and im-prove the stress resistance of rapeseed.This study can provide a theoretical basis and technical support for crop stress resistance.
