Meta Analysis of the Effects of Arbuscular Mycorrhizal Fungi on the Growth and Fruit Traits in Strawberry
Arbuscular mycorrhizal(AM)fungi generally can improve plants'growth and resistance.However,it has not been clarified whether AM fungi uniformly regulate strawberry phenotypes and fruit characteristics,regardless how the strawberry habitats may be.In this study a meta-analysis method was used to integratedly analyze the effects of AM fungi on dry weight,root architecture,nitrogen(N)and phosphorus(P)contents,fruit yield,and fruit traits of strawberries.The results showed that AM fungi could significantly increase dry weights of aboveground parts and roots of strawberries,promote root elongation,enhance root surface area,and thus adjust root architecture.AM fungi sig-nificantly increased N and P contents of shoots and roots.Funneliformis mosseae significantly promote strawberries to take in N and P and increased biomass.AM fungi increased the fruit number and total yield,and strengthened the ac-cumulation of total anthocyanidin,phenolics,flavones,and ascorbic acid in fruits,and accordingly improved the an-tioxidant properties of fruits,and do not significantly affect the total soluble solids(TSS),titratable acidity(TA),and TSS/TA ratio.The study suggest that AM fungi are beneficial to promote strawberry growth and fruit production,and raise the content of antioxidant substances in fruits,revealing the potential of AM fungi application on green pro-duction of strawberry.
