The plant growth-promoting Pseudomonas strains, WR83 (Pseudomonas fluorescens), WR9-11 (Pseudomonas sp.) and WR9-16 (P. putida), which induced resistance systematically in watermelon to gummy stem rot were investigated on their induced systemic resistance (ISR)-related characteristics. The pyoverdine production was repressed in the standard succinate medium by increasing the concentration of FeCl₃. But the iron-binding ability on chrome azurol S agar media (CAS) was observed only in the strains, WR8-3 and WR9-16. When the two strains were mutated, the resulting ironbinding siderophore-negative mutants, WR8-3m and WR9-16m, failed to promote the growth of watermelon and to induce resistance. The strains, WR8-3 and WR9-16, slightly inhibited the growth of Didymella bryoniae at a low concentration of FeCl₃ on King's medium B, but not to exert control effect. The strain WR9-11 showed antagonism in the concentration of FeCl₃ from 0 to 1,000 μM. When the crude lipopolysaccharide of each strain was treated in the rhizosphere of watermelon, mean lesion area was similar to that of the untreated control. The strains, WR9-11 and WR9-16 produced some level of hydrogen cyanide (HCN). Salicylic acid production was not detected in all of the strains.
