4 CONCLUSION
Comprehensive analysis showed that high
temperature stress had significant effects on the
physiological parameters and chlorophyll
fluorescence parameters of Dianthus hybridus.
Inoculation with AMF can alleviate the damage
caused by high temperature stress to the activity of
antioxidant enzymes, osmotic regulators and
photosynthetic electron transport system, and
improve the heat resistance of Dianthus hybridus to a
certain extent.
