“…However, it is observed in Table 1 Regarding the global plants growth on the substrates, there was recorded significant differences among them (Table 3). These results corroborate those described by Moreira et al (2006) in 'Pérola' pineapple and Oliveira et al (2014), in three banana cultivars; both cultures acclimatized on different substrates. Was observed that substrate semi-composed pine bark provided the highest means for leaf area and shoot dry mass.…”

The in vitro propagation techniques are commonly used to produce ornamental pineapple seedlings in commercial scale, aiming to attend the growers with genetic and sanitary quality seedlings. However, the choice of the ideal substrate is essential for the acclimatization and growth stage of the seedlings propagated by this technique, since some substrates can increase the seedling mortality and/or limit the seedling growth due to its physical and chemical characteristics. Thus, the aim of this study was to evaluate the acclimatization of ornamental pineapple [Ananas comosus (L.) Merr. var. ananassoides (Baker) Coppens & Leal] on different substrates. Seedlings with approximately seven centimeters, obtained from in vitro culture, were transplanted into styrofoam trays filled with the following substrates: sphagnum; semi-composed pine bark; carbonized rice husk; sphagnum + semicomposed pine bark; sphagnum + carbonized rice husk; and semi-composed pine bark + carbonized rice husk. Each treatment was replicated five times using 10 plants. At 180 days, there were evaluated the following variables: survival percentage, plant height, number of leaves, leaf area, largest root length, and shoot and root dry matter. The substrate semi-composed pine bark + carbonized rice husk presented the lowest mean (62%) for survival percentage. The semi-composed pine bark and semi-composed pine bark + carbonized rice husk treatments presented significant increments in some evaluated biometric characteristics. The semi-composed pine bark is the most favorable substrate for the A. comosus var. ananassoids acclimatization. Keywords: Ananas comosus var. ananassoides, Bromeliaceae, propagation, potting media. RESUMO Aclimatização e crescimento de mudas de abacaxi ornamental em substratos orgânicosTécnicas de propagação in vitro são utilizadas visando produzir mudas de abacaxi ornamental em escala comercial, a fim de atender os produtores com mudas de qualidade genética e sanitária. Porém, a escolha do substrato ideal é essencial na etapa de aclimatização e crescimento das mudas propagadas in vitro, visto que alguns substratos podem proporcionar a mortalidade das plântulas ou limitar o crescimento das mudas, devido às suas características físicas e químicas. Assim, objetivou-se avaliar a aclimatização do abacaxi ornamental [Ananas comosus (L.) Merr. var. ananassoides (Baker) Coppens & Leal] em diferentes substratos. Plântulas com aproximadamente 7 cm, oriundas de cultivo in vitro, foram transplantadas em bandejas de isopor contendo os seguintes substratos: esfagno, casca de pinus semi-compostada, casca de arroz carbonizada, esfagno + casca de pinus semi-compostada, esfagno + casca de arroz carbonizada e casca de pinus semi-compostada + casca de arroz carbonizada. Cada tratamento foi constituído de cinco repetições contendo dez plantas cada. Aos 180 dias avaliou-se as variáveis: porcentagem de sobrevivência, altura da planta, número de folhas, área foliar, comprimento da maior raiz, e massa seca da parte aérea e raízes. O substrato ca...

“…These values are close to those found in the present study, but not within the ideal range, even though the plants were fertilized, indicating that other factors may have affected the absorption or availability of nutrients, such as growing conditions in the greenhouse: light, pot size, type of substrate, etc. (Martins et al, 2011;Oliveira et al, 2014;Rodrigues et al, 2022).…”

Plant growth-promoting bacteria emerge as an alternative to attenuate abiotic stresses in plants such as salinity. The objective of this study was to evaluate the effects of Bacillus sp. strains 186 and 109 on the acclimatization of banana cv. ‘Prata Catarina’ irrigated with saline water. The experiment was conducted in a completely randomized design in a 4 × 2 factorial scheme, with 4 growth-promotion treatments, subjected to 2 levels of electrical conductivity of irrigation water. Irrigation with saline water decreased the number of leaves, leaf area, transpiration rate, stomatal conductance, and CO2 assimilation rate in banana leaves, regardless of inoculation with bacterial strains. The use of Bacillus sp. strain 109 promoted increments in phosphorus and iron contents in banana plants irrigated with low-salinity water.
