Effect of SYST2-VOCs on Plant growth promotion of tobacco in vitro. For divided plate system (a and b), seven germinated seedlings were transplanted in one partition and bacteria were spot inoculated on the other partition. For “two plate system”, germinated seedlings were grown in larger plates having soil mixed with vermiculite as a medium for growth, while bacterial strains were inoculated in small plates. The effect of SYST2-VOCs on plant growth was observed by recording fresh green weight (a) and dry weight (b) after two weeks of exposure. In “two plate system” effect was observed visually which showed different growth in control (C1), exposed to SYST2-VOCs (C2), and exposed to DH5-VOCs (C3). Fresh weight of tobacco seedlings (d) and dry weight (e) of seedlings were recorded after 10 days in “two plate system”. Error bars indicate the standard deviation of the mean (n = 5). Different lower case letters above the columns represent significant differences between treatments at P = 0.05. Experiments were repeated three times with similar results
