Figure 6: Indole-3-acetic acid production by the bioactive endophytic bacterial recovered from Datura stramonium and noted after 24 and 48 h of incubation at 28 ± 2°C in Luria-Broth medium. S37: Stenotrophomonas maltophilia str. S37 (KR818085) isolated from stems; S40: Bacillus mojavensis str. S40 (KR818086) isolated from flowers. For each incubation period, bars sharing the same letter are not significantly different according to Student Newman Keuls test at P ≤ 0.05.
