FIGURE 3.
Effect of selected root-associated bacterial strains on growth of A. nordmanniana under greenhouse conditions. Seeds were inoculated with bacterial cell suspensions and sowed pots with non-sterilized soil, which were kept at the greenhouse at 18°C for 30 days. After 30 days of growth, the seedlings were scanned (A) and measured for root length (cm) (B), root volume (cm3) (C), and number of root tips (D). The figure shows the average values of six replicates per treatment. Each bar represents the Standard Error.
