Figure 3.

Effect of foliar spray with Ch and NPs on shoot (a,b) and root biomass (c,d) of plants inoculated or non-inoculated with R. irregularis, flowers number of inoculated plants (e,f), mycorrhization rate (g,h), and relative transcript levels of β-Tubulin (RiBtub) (i,j) and AM-specific phosphate transporter (SlPT4) genes (k,l). Data are represented as the mean ± SD with n =8 for Ch and n = 4 for NPs, different letters show significantly different values after one-way ANOVA followed by Duncan’s multiple range test (p ≤ 0.05).
