Promoção de crescimento e supressão da brusone em arroz irrigado pela utilização de bactérias

Abstract

In an experiment conducted in a controlled laboratory environment, 25 bacteria were inoculated into the BRS Catiana cultivar. The 25 bacteria were tested in a completely randomized design with five replications of ten plants per cup in autoclaved sand. The following bacteria were used: AGL 1, AGL 2, AGL 3, AGL 4, AGL 5, AGL 6, AGL 7, AGL 8, AGL 9, AGL 10, AGL 11, AGL 12, AGL 13, AGL14, AGL15, AGL16, AGL 17, AGL 18, AGL 19, AGL 20, AGL 21, AGL 22, AGL 23, AGL 24, AGL 25. Autoclaved water was used as a control. The seeds were submerged in a bacterial suspension and planted. After 14 days of planting, a bacteria-rich application was performed along with fertilization. In Petri dishes containing BDA medium, the pathogen was placed in the center of the plate, and the bacteria were streaked at a distance of 2.5 cm from the fungal disc. The plates were incubated in a BOD chamber for seven days. Twenty-five bacteria were tested, and the control consisted of BDA plates containing only the mycelial disc of the phytopathogenic fungus.
