Fig. 2: Growth of Rhododendron fortunei microcuttings in a sterilized peat-based substrate.

a Microcuttings rooted in the peat-based substrate without (CK) and with inoculation of Om19 (Om19) after 120 days of growth. b Fresh and dry weights of 40 rooted cuttings grown in the peat-based substrate without (CK) and with Om19 inoculation. Bars represent standard errors (n = 3) where (**) indicates significant differences in a given parameter between microcuttings uninoculated (CK) and inoculated (Om19) with Om19 based on Tukey’s HSD test at P < 0.01 levels
