Abstract:
Arbuscular mycorrhizal (AM) fungus is symbiotic fungus widely distributed in soil.Research had shown that AM fungus could affect the plant secondary metabolism.Taking watermelon ‘Jingxin No1’ and soils continuously grown with watermelon for different years as materials.The effect of AM fungus on the content of secondary metabolites in watermelon roots and the residue of root’s exudates in soils were studied in different years’ continuous cropping soil.The results showed that AM fungus could effectively improve the content of total phenols in the roots，enhance the resistance of watermelon root disease，and reduce the accumulation of phenolic acids in the soil.AM fungus had a strong inhibitory effect on the accumulation of continuous cropping soil phenol acids，regardless of the replanting years.The changing trends of root’s total flavonoid and total phenol were consistent，showing a rising trend.It showed that AM fungus effectively raised the roots of the content of secondary metabolites and to some extent，increased content of flavonoid in continuous cropping soil.The effect of AM fungus on the content of flavonoid in different years’ continuous cropping soils was also different.
