Trichoderma cf. asperellum and plant-based titanium dioxide nanoparticles initiate morphological and biochemical modifications in Hordeum vulgare L. against Bipolaris sorokiniana

Table 4 Pearson’s correlation matrix between growth parameters of barley plants (shoot height, shoot fwt and root fwt)), photosynthetic pigments (Chl a, Chl b and total pigments) and other biochemical parameters (total sugars, MDA and H₂O₂). Each square indicates the Pearson’s correlation coefficient of a pair of parameters
