Effects of Trichoderma atroviride LZ42 on the phenotypic characteristics of aerial dry weight (a) and root dry weight (b) of tomato seedlings. The box indicate the range of the central 50% of the data from each treatment. The central lines mark the median value. The error bars across the boxes indicate the standard errors. Asterisks (*) in the figure indicate significant differences derived from two-sample comparisons (P = 0.05). NC indicates the treatment with uninfested soil. MC indicates the treatment amended with 50 g of the talc formulation alone. MT indicates the treatment amended with 50 g of the strain LZ42 formulation
