Ramos,Luan da Luz; Rodrigues,Elisete Pains; Silva,Mayara Barbosa; Oliveira,Jessica Ellen; Zuluaga,Mónica Yorlady Alzate; Milani,Karina Maria Lima; Oliveira,André Luiz Martinez de.
ABSTRACT Plant growth-promoting bacteria (PGPB) comprise part of plant microbiome of biotechnological interest due to their potential to decrease the use of agrochemicals in agriculture. Among the commonly found PGPB species, the Pseudomonas genus is known for high competitiveness and efficiency in expressing growth-promotion traits. To increase the contribution of diazotrophic Pseudomonas sp. to the plant nitrogen nutrition, the strain AZM-01 was chemically mutagenized with methyl methanesulfonate (MMS), following the selection for resistance to ethylenediamine (EDA). From the 13 EDA-resistant mutant strains selected, four showed increased the ammonium excretion, with the highest value reaching up to 284% increase as compared to the wild strain, and six...

Growth promotion of pineapple 'vitória' by humic acids and burkholderia spp. during acclimatization Rev. Bras. Ciênc. Solo
Baldotto,Lílian Estrela Borges; Baldotto,Marihus Altoé; Canellas,Luciano Pasqualoto; Bressan-Smith,Ricardo; Olivares,Fábio Lopes.
In vitro propagation of pineapple produces uniform and disease-free plantlets, but requires a long period of acclimatization before transplanting to the field. Quicker adaptation to the ex vitro environment and growth acceleration of pineapple plantlets are prerequisites for the production of a greater amount of vigorous, well-rooted planting material. The combination of humic acids and endophytic bacteria could be a useful technological approach to reduce the critical period of acclimatization. The aim of this study was to evaluate the initial performance of tissue-cultured pineapple variety Vitória in response to application of humic acids isolated from vermicompost and plant growth-promoting bacteria (Burkholderia spp.) during greenhouse...

Optimization of the production of mycorrhizal inoculum on substrate with organic fertilizer BJM
Coelho,Ieda R; Pedone-Bonfim,Maria VL; Silva,Fábio SB; Maia,Leonor C.
The system for production of inoculum of arbuscular mycorrhizal fungi (AMF) using sand and vermiculite irrigated with nutrient solution is promising. However, organic amendments added to the substrate can stimulate sporulation of AMF and replace the nutrient solution. The aim of this study was to maximize the production of AMF (Acaulospora longula, Claroideoglomus etunicatum, Dentiscutata heterogama and Gigaspora albida) using selected organic substrates (vermicompost, coir dust and Tropstrato) together with sand and vermiculite. The production of spores varied among the tested AMF and according to the organic source added to the substrate. The vermicompost promoted higher sporulation of A. longula in relation to the other AMF and substrates. The...
