Plants grown under gnotobiotic conditions were inoculated with bacteria and on the same day infested with Pythium ultimum. After 3 weeks of growth in artificial soil under sterile conditions, plants were harvested and assessed for fresh weights.
Plant fresh weights are expressed as percentages of weights of corresponding untreated control plants (total plant weights: Arina, 3.04 g; Zinal, 2.94 g; Cimetta, 2.75 g; root weights: Arina, 1.44 g; Zinal, 1.46 g; Cimetta, 1.42 g). Values are the means of two experiments with four replicates each. Values within the same column followed by the same letter are not significantly different according to Fisher's protected LSD (P ≤ 0.05).
