“…However, surprisingly, this genus was not detected in faba bean rhizosphere. Most of the other genera found in our study also had prior description as potential PSB strains (Araújo et al, 2021;Emami et al, 2020;Mitra et al, 2020;Rodrı ǵuez and Fraga, 1999), except for Sanguibacter, mainly known as N2 fixing bacteria with biocontrol properties against nematode infestation (Alishahi et al, 2020;Moussa and Zawam, 2010). To our knowledge, the present study reveals for the first time a Sanguibacter inulinus isolate with phosphate solubilization abilities and can thus be described as a PSB.…”

“…Micropropagation of banana is a successful protocol to produce healthy transplants or explants, which could be placed in artificial culture media in an aseptic and controlled environment [17]. During the current study, banana plantlets had the highest survivorship by 95.3% by application of the highest dose of nano-Cu (100 mg L −1 ), whereas the highest dose of nano-Se recorded 94.3% (Table 2).…”

“…Banana fruits have excellent nutritional value due to their high content of carbohydrates, minerals (K, P, Ca, Mg, and Fe), and vitamins like riboflavin (B2), niacin (B3), A, C and B6 [14,15]. The growth, rooting and acclimatization of micropropagated banana transplants may be controlled by many factors like endophytic micro-organisms [16], aseptic environments [17], nutrients such as magnesium [18], potassium, and nitrogen [19], and growth media content [20]. Micropropagated banana transplants should have high health and be cultivated in suitable artificial culture media, free from diseases and pests to guarantee a high production [17].…”

Micropropagated banana transplants should have high health and be cultivated in suitable artificial culture media, free from diseases and pests to guarantee a high production [17]. The acclimatization of in vitro grown banana plantlets is a very important step for commercial production in an ex-vitro environment by hardening for high quality banana transplants as followed for several horticultural crops like orchid [21].…”

Acclimatization of In Vitro Banana Seedlings Using Root-Applied Bio-Nanofertilizer of Copper and Selenium

The production of in vitro banana transplants has become an important practice in the global banana production. Proper and enough nutrients are needed for banana production particularly during the acclimatization period. To avoid the environmental problem resulting from the chemical fertilizers, nanofertilizers of Se and Cu were separately applied during the acclimatization of banana. The biological form of nano-Cu (50 and 100 mg L−1) and nano-Se (25, 50, 75, and 100 mg L−1) were studied on acclimatized banana transplants under greenhouse conditions. Both applied nanofertilizers enhanced the growth of transplant by 10.9 and 12.6% for dry weight after nano-Se and nano-Cu application up to 100 mg L−1, respectively. The survival rate was also increased by increasing applied doses of both nanofertilizers up to 100 mg L−1, whereas the highest survival rate (95.3%) was recorded for nano-Cu. All studied photosynthetic pigments and its fluorescence were improved by applying nanofertilizers. Studied antioxidant enzymatic activities (CAT, PPO, and POX) were also increased. A pH decrease in the growing medium was noticed after applying nano-Cu, which may explain the high bioavailability of studied nutrients (N, P, K, Cu, Fe, Se, and Zn) by banana transplants.

“…En ninguno de los dos experimentos se encontró efecto sobre el peso seco del pseudotallo, hojas y cormo. Sin embargo, inoculaciones de Posada et al (2016) con Bacillus subtilis y de Araújo et al (2021) con B. thuringiensis en el cultivar Prata Ana, incrementaron el peso seco de tallo (34 a 39 %), raíces (68 %) (Posada et al, 2016) y hojas (32 %) (de Araújo et al, 2021).…”

Introducción. Las rizobacterias promotoras de crecimiento vegetal (RPCV) podrían ser utilizadas como una fuente alternativa al uso de fertilizantes nitrogenados convencionales en el cultivo de banano (Musa AAA). Es necesario la búsqueda de bacterias adaptadas a las condiciones de los suelos de Costa Rica y del cultivo del banano. Objetivo. Evaluar el efecto de la inoculación de cuatro aislamientos de Bacillus cereus sobre el crecimiento y el contenido de nitrógeno (N) de plántulas de banano en condiciones de invernadero. Materiales y métodos. Se realizaron dos experimentos simultáneos entre abril y septiembre 2020, en el Centro de Investigaciones de la Corporación Bananera Nacional (CORBANA), La Rita, Limón, Costa Rica. Se inocularon cuatro aislamientos de B. cereus en plantas de banano a las cuales se les fertilizó con cuatro dosis de nitrógeno semanalmente. El diseño consistió en parcelas divididas, donde la parcela principal estuvo conformada por cuatro niveles de N: 0, 33, 66, 100 % de la dosis; y la parcela pequeña por los aislamientos bacterianos y el testigo. Se midieron las variables altura de planta, contenido de clorofila, el área foliar de la tercera hoja, peso fresco y seco de raíces, cormo, pseudotallo y hojas, así como el contenido de nitrógeno en cada órgano. Resultados. El experimento 1: las plantas inoculadas con el aislamiento SER-23 presentaron el mayor peso seco total. En el experimento 2: el mayor peso seco total se observó en las plántulas inoculadas con el aislamiento BF-98. La aplicación de las bacterias SER-23 y BF-98 aumentó significativamente el contenido de nitrógeno en todos los órganos evaluados. Conclusiones. La inoculación de los aislamientos de Bacillus cereus SER-23 y BF-98 estimuló el aumento de la biomasa y contenido de nitrógeno en las plantas de banano, este incremento dependió de la disponibilidad de nitrógeno y el tipo de suelo.
