Effect of Arabidopsis growth with Trichoderma strains at 5 dpi. (A) Representative photographs of 13 day-old Arabidopsis (Col-0) plantlets grown on PDA or MS media after 5 dpi with T. atroviride (Ta) and T. virens (Tv). Trichoderma species were inoculated as follows: direct interaction (At-MS), split interaction without contact when the fungus was grown on MS medium (At/MS), split interaction without contact when the fungus was grown on PDA medium (At/PDA), and as control plantlets grown on MS without any inoculation. The scale bar corresponds to 2 cm. Physiological parameters were examined: (B) fresh weight (mg) (n = 15), (C) primary root length (n = 15), and (D) number of lateral roots per plant (n = 15). Barplots present mean ± SD values of dependent variables according to our experimental treatments. Letters refer to bootstrap pairwise two-sample robust tests; treatments without shared letters are significantly different.
