Figure 2.

Seeds of tomato after surface sterilization were placed per each test tube and the resulting seedlings were grown in the presence of 20 µl of GBSC56 culture (10⁷ CFU/mL) in an airtight jar incubated at 25 °C for 12 days. The effect of GBSC56-VOCs on seedlings was observed visually (A) and calculated by the difference (B) in (a) fresh weight, (b) dry weight, (c) shoot length, and (d) root length after exposure to GBSC56-VOCs. Error bar represents the mean standard deviation of each treatment. The small letters above the columns indicate significant difference. The significant difference among the treatments was calculated through the Tukey HSD test at p ≤ 0.05.
