Promoting Seed Germination of Some Plant Species by Rhamnolipid Produced by Pseudomonas aeruginosa

Figure 4

Germination rate of onion seeds (Allium cepa) treated with different concentrations of rhamnolipid. The concentrations of rhamnolipid 0.25 and 0.50 g/L have significant effect on seed germination from the first day of sowing.
