“…and the banana tree (SOUZA et al, 2013). The application of twenty different triple combinations of PGPB in banana plants indicates that the isolates EB-40, EB-51 and EB-194, all belonging to the genus Bacillus sp., promoted significant increases in the nitrogen content in the shoot dry matter of banana seedlings (SOUZA et al, 2016).…”

“…According to Andrade et al (2014) study, this isolate besides showing the ability to fix the N, also demonstrated the ability to solubilize phosphorus of low solubility under in vitro conditions. Souza et al (2016) report that the combination of diazotrophic bacteria, phosphate solubilizing bacteria and indole acetic acid synthesizers promoted significant increases in the length, pseudostem diameter, number of leaves, shoot and root fresh mass and dry mass of 'Prata Ana' banana seedlings.…”

“…The microorganisms are able to confer certain characteristics to the plants, such as greater resistance to conditions of water stress; change their physiological properties; produce plant hormones and other compounds of secondary metabolism (SOUZA et al, 2015). On the other hand, the endophytic organisms find in the plant a habitat with nutrients and less competition with other microorganisms (PEIXOTO NETO et al, 2004).…”

The use of bio-fertilizers and microbial inoculants that promote plant growth and increased yield has been accepted as an alternative to reduce the use of chemical fertilizers. The objective of the present study was to evaluate the effect of plant growth promoting bacteria inoculation on growth and quality of micropropagated banana seedlings ‘Prata Anã’. The experimental design was completely randomized, with four replications and the treatments consisted of 24 isolates of endophytic bacteria. The isolates EB-50 (Bacillus sp.) and EB-133 (Bacillus amyloliquefaciens) characterized as diazotrophic, the EB-51 (Bacillus pumilus) indicate for inorganic phosphate solubilization and EB-55(Bacillus subtilis) and EB-40 (Bacillus sp.) indole-3-acetic acid producers have provided significant increases for length, pseudostem diameter, fresh masses and dry masses in ‘Prata Anã’ micropropagated banana seedlings.

“…The association of plant growth-promoting bacteria with micropropagated banana plantlets has been reported to be beneficial under many environmental conditions. These microorganisms have been associated with and are responsible for biological nitrogen fixation, resistance to saline and hydric stress, and promotion of plantlet growth as well as root development (Azevedo et al, 2000;Andrade et al, 2014;Souza et al, 2016).…”

Increased planting density, different types of thinning management, and the use of beneficial microorganisms have been adopted as strategic tools in the effort to increase crop yields in a sustainable manner. This investigation evaluated the growth and production of 'Prata Anã Gorutuba' banana (Musa spp., AAB) under different plant densities during two production cycles in the semiarid region of Minas Gerais, Brazil. Micropropagated plantlets were also inoculated with endophytic bacteria and cultivated as part of two mat management strategies. Planting density varied between 1,680 and 3,920 plant ha-1. During the experiment, water was less than optimal because of rationing due to drought in the region. Under field conditions, there was no difference between bacterially inoculated and non-inoculated plants. The dense planting system increased the crop cycle. The highest-density planting treatment (3,920 plant ha-1) resulted in the highest yield in the first cycle, but no net income was observed. However, the high-density planting treatments resulted in the highest yields and gross incomes in the second production cycle. Management with thinning of plants up to 10-months-old and thinning up to harvest associated with high planting density increased the length of the production cycles. Although the water restriction experienced in the first and second crop cycles, the vegetative and productive traits of 'Prata Anã Gorutuba' banana did not compromise the objectives of this study.

“…PGPR promote nutritional growth, antagonism to pathogens, and stimulation of plant host defences (Choudhary & Johri, 2009;Hayat et al, 2010) and several studies have highlighted the growth-promoting activity of these microorganisms in banana plants. The rhizobacteria present positive responses to physiological growth characteristics, as well as to nutritional parameters of banana plants (Baset Mia et al, 2010;Souza et al, 2016).…”

In the banana production system, a sustainable alternative for producing quality plantlets would be inoculation with plant growth-promoting bacteria (PGPB). Therefore, this study aimed to evaluate the growth-promoting potential of a bacterial biomass in micropropagated banana plantlets cultivar Prata Catarina, and to identify the mechanisms involved in plant-microorganism interactions. In vitro, the biochemical assays tested were the solubilisation of phosphates, production of enzymes, production of ammonia, siderophores, and indole acetic acid. In the in vivo tests, the plants were bacterised (109CFU mL-1) in two phases: acclimatisation, and cultivation in plastic bags. The design was a randomised block with 9 and 7 repetitions per treatment, which were: T1: control; T2: plants treated with isolate E2 (Bacillus pumilus group); T3: plants treated with RAB9 isolate (B. pumilus) for each phase. Bacterial isolates were capable of producing cellulases, amylases, pectinases, lipases, proteases, and siderophores. The plants gained in height, root length, root dry mass, pseudostem diameter, and leaf area. It is concluded that the PGPB can promote the growth of micropropagated banana plantlets through the production of enzymes and siderophores.
