In this study, the results revealed that the Trichoderma
treatments highly significantly increased photosynthetic
pigments of maize plants as compared to control. Hexon
et al. (2009) showed that Trichoderma spp. in
Arabidopsis thaliana increased root size which resulted
into increase in shoot size which translates into increase
in the shoot biomass; these resulted in the increase of
photosynthetic pigments. Trichoderma-T22 has been
shown in maize to increase plant greenness (Mastouri,
2010; Shoresh et al., 2010).
