“…Treatment with this formulation consistently increased rice grain yield. P. fluorescens is one of the known plant growth promoting rhizobacteria (PGPR), and it produces plant growth regulators such as gibberellins, cytokinins and indole acetic acid (Dubeikovsky et al, 1993). The increased yields obtained in the field trials may have resulted from both disease control and growth promotion (Vidhyasekaran & Muthamilan, 1995).…”

Development of a powder formulation of Pseudomonas fluorescens for control of rice blast

Pseudomonas fluorescens strain Pf1, inhibitory to the growth of the rice blast pathogen Pyricularia oryzae in vitro, was developed as a talc-based powder formulation. When rice seeds were treated with this formulation, the bacteria spread to roots, stems and leaves of the plants and protected against leaf infection by P. oryzae. When applied as a foliar spray, the bacteria survived on the leaves. The powder formulation controlled leaf blast under greenhouse conditions. In tests as a seed treatment and foliar spray in four field trials it effectively controlled the disease and increased grain yield.

“…The production of phytohormones has also been reported in other PGPR strains including Azotobacter chroococcum (Muller et al, 1989), Azospirillum spp. (Remans et al, 2008), Pseudomonas fluorescens (Dubeikovsky et al, 1993) and P. putida (Taghavi et al, 2009). Barazani and Friedman (1999) reported that high levels of IAA (76.6 µm) were excreted by four deleterious rhizobacteria (Micrococcus luteus, Streptoverticillium sp., Pseudomonas putida a nd Gluconobacter sp.)…”

Clusterbean [Cyamopsis tetragonoloba (L.) Taub.] is an important commercially utilizable crop grown in arid zone of India. Microorganisms present in the rhizosphere of this crop produce various plant growth-promoting substances and enhance the availability of nutrients to the plants. Therefore, fifty five bacterial isolates obtained from the rhizosphere of clusterbean were explored for beneficial characteristics. Twenty rhizobacterial isolates produced indole acetic acid ranging from 3.9 to 24.7 µg/mL. Only six isolates HCS7, HCS19, HFS7, HFS9, HFS10 and HFS12 showed d-aminolevulinic acid production varying from 1.3 to 7.0 µg/mL. Fourteen isolates showed solubilization of potassium on mica containing Aleksandrov medium plates. Stimulation of root and shoot growth of clusterbean seedlings on water agar plates was observed by inoculation of eleven rhizobacterial isolates at 5 and 10 days of growth whereas some isolates showed stunting effect on the growth of shoot and root as compared to uninoculated seedlings. At 60 days of plant growth, inoculation of Bradyrhizobium strain GSA11 and Rhizobium strain GSA110 showed significant nodulation and their inoculation resulted in 141.94 and 151.43% gains in shoot dry weight, respectively under chillum jar conditions. Coinoculation of Bacillus isolate HCS43 with Rhizobium strain GSA110 formed 48 nodules/plant and plant dry weight was enhanced by 190.09% in comparison to uninoculated control plants.

“…Os isolados bacterianos presentes no solo são, em sua maioria, capazes de produzir AIA (SPAEPEN et al, 2009). Um mutante de P. fluorescens super produtor de AIA estimulou o desenvolvimento radicular de estacas de groselheirapreta (DUBEIKOVSKY et al, 1993). A produção de AIA por rizobactérias também foi observada em estudos com tomateiro (PELZER, 2010) e orquídeas (TSAVKELOVA et al, 2007), demonstrando que é um mecanismo que atua na promoção do crescimento de plantas.…”

Potencial de rizobactérias no crescimento de mudas de sibipiruna (caesalpinia peltophoroides BENTH)

e Isac Jonatas Brandão 5 RESUMO -Este trabalho objetivou avaliar o potencial de isolados de rizobactérias na germinação de sementes e no crescimento de mudas de sibipiruna (Caesalpinia peltophoroides). Testaram-se os isolados pré-selecionados para eucalipto, Ca, FL2, MF2, MF4, RC3, R1, 3918, S1, S2 e CIIB. Para tanto, amostras de substrato à base de vermiculita e casca de arroz carbonizada (1:1) foram tratados com 5 mL de uma suspensão de cada isolado (OD 540 = 0,2 A)/ tubete de 55 cc de capacidade, correspondendo a cerca de 10 ufc/mL. O delineamento experimental foi inteiramente casualizado (DIC) com cinco repetições por tratamento, com 20 sementes cada. Aos 40 dias, avaliaram-se a porcentagem de germinação e a massa seca de raízes e da parte aérea. Verificou-se aumento significativo em matéria seca de raiz e da parte aérea para todos os isolados de rizobactérias testados, em relação à testemunha. Todos os isolados proporcionaram aumento significativo na germinação, à exceção do 3918 e CIIB que não diferiram da testemunha. Entre os isolados testados, quatro destacaram-se como os mais promissores (FL2, MF4, MF2 e CIIB). Os resultados obtidos mostram ganhos significativos na produção de mudas, sem nenhum ajuste no manejo ou na estrutura do viveiro. Além desse ganho direto, pode-se ter um melhor aproveitamento da estrutura física dos viveiros, ao se diminuir o tempo de formação das mudas, reduzindo-se o custo de produção.Palavras-chave: Sementes, PGPR, Produção de mudas.
