(a) Stomatal conductance (nmol/m2 s) and (b) maximum PSII quantum efficiency of P. caerulea plants after seven days from the first treatment and after 60 days from the first treatment with plant biostimulants. C—control (no treatment with plant biostimulants, treated only with water); T1—foliar treatment with Trichoderma consortium suspension, 106 cfu/mL, equiv. to 1011 spores/ha; T2—foliar treatment with Trichoderma consortium suspension, 108 cfu/mL, equiv. to 1013 spores/ha; T3—foliar treatment with the reference product, consisting of plant extracts, essential oils and fatty acids in an oil/water emulsion, and extract of the seaweed Ascophyllum nodosum, equiv. to 3 L/ha. The values presented are means  ±  standard error (n  =  40 plants). Columns labeled with different letters, compared between the different treatments (C, T1, T2, and T3) within each time period (after 7 days and, respectively, after 60 days) are significantly different at p < 0.05.
