Grey
mold disease of eggplant (Botrytis
cinerea Pers.) causes serious yield losses on eggplant (Solanum melongena L.) production in
greenhouses in Turkey. In this study, effects of some plant growth regulating
rhizobacteria against grey mold disease were investigated.Bacillus spp. (B379c, B10a
and 76A-1) and Pseudomonas spp.
(P07-1, P07-4 and 85A-2)
isolates inhibited mycelial development of B. cinerea (Bc-TR07) under in
vitro conditions at varying rates (21-33%). Among the
PGPR isolates, P. aeruginosa (P07-1)
was found as the most successful isolate in pot experiments with an efficiency
rate of 58.1%, compared to positive control containing only pathogen inoculum.
Similarly, this isolate significantly increased some plant growth parameters.
The P07-1 isolate resulted a 27.0% increase in total proline content of
eggplants 72 h after pathogen inoculation, and in the same period, defense
enzymes catalase (CAT) and peroxidase (POX) were also increased 22.8% and 27.7%
respectively, compared to positive control. This isolate was followed by P. putida (P11-4) and then B. amyloliquefaciens (76A-1) by means of
CAT and POX enzymes activity. The major disease
suppression mechanisms of the tested PGPR isolates were identified as their
plant growth regulation and resistance induction abilities.
