Abstract:
The effects of AM fungus inoculation combined with salicylic acid (SA) on cucumber growth and low temperature resistance were studied in greenhouse pot experiment with cucumber as the test material to evaluate the synergistic effect of SA+AM fungus.The results showed that exogenous SA or/and AM fungi inoculated at low temperature could significantly promote the growth of cucumber plants,and significantly improve the fresh weight,dry weight and antioxidant enzyme activity of leaves.Among them,cucumber leaves treated with exogenous SA+AM fungi had the highest antioxidant enzyme activity.The activity of antioxidant enzyme increased first and then decreased,and reached its peak earlier.Inoculation with AM fungi combined with SA could enhance cold tolerance and promote growth and development of cucumber.
