Post-harvest quality of ‘Vitória’ pineapple as a function of the types of shoots and age of the plant for floral induction

Abstract

For the production and quality of pineapple fruits, the appropriate choice of the type of propagule to be used combined with the management of the ages for floral induction are important factors to reach the maximum of desirable characteristics that will define the success in the production of the pineapple and its good acceptance in the market. The objective of this research was to evaluate the post-harvest quality of fruits developed from different types of shoots and ages of floral induction of ‘Vitória’ pineapple. The experiment was carried out in a complete randomized block design with four replications. The plots were made up of the shoots (slip and sucker) and the subplots were composed of the different ages of floral induction (8, 10 and 12 months after planting and natural flowering). Evaluations of biomass characteristics of fruits with and without crown, circumference, length, diameter, firmness, translucency, pulp color and physicochemical quality were performed. No significant interaction was observed for the biometric and biomass variables, and the type of shoots influenced only the crown biomass and the central cylinder diameter, which were higher in the slips. In addition, for the attributes color, translucent area and firmness, no interaction was found, and they were influenced only by the induction times, except for the variable color referring to the intensity of green and red colors. Regardless of the types of the shootss evaluated in the environmental conditions of planting carried out in April 2015, the fruits originated from natural inductions and inductions at 12 months presented greater firmness, a desirable characteristic for export and industrialization, mainly for the processing of slices of pineapple, pieces in syrup and crystallized. The slips natural induced and induced at 12 months provided fruits with a greater ratio between soluble solids and acidity.

Fruit quality of pineapple ‘Vitória’ under macronutrients and boron deficiency

“…These values are higher than those found in the fruits of 'Perola' and 'Smooth Cayenne' cultivars in studies by Reinhardt and Medina (1992) and similar to those found by Viana et al (2013) and Küster et al (2018) with the 'Vitoria' cultivar. On the other hand, Barker et al (2018) and Berilli et al (2014) reported higher average values of 16°Brix for 'Vitoria' cultivar. The soluble solids content observed in fruits from plants grown with complete solution is within the minimum parameter for commercialization of pineapple fruits, which are the soluble solids content of 12°Brix (BRASIL, 2002).…”

Desenvolvimento de abacaxizeiros e qualidade de frutos sob diferentes métodos de controle de plantas daninhas

“…O comprimento de frutos foi influenciado somente pelo cultivar, com destaque para o 'Pérola', o qual atingiu em média 20 cm, semelhante à obtida por Reinhardt et al (2002). A média obtida para o 'Vitória' foi superior à descrita em outros trabalhos recentes para a Região Litoral Norte e com indução floral menor um mês menor (dez meses após o plantio), Barker et al (2018) produziu frutos com 8,79 cm, enquanto Küster et al (2017) no cultivo sequeiro, variando o plantio em julho e setembro, obteve frutos com média de 11,51 cm. A variação é associada às condições edafoclimáticas no plantio e indução floral, que podem influenciar significativamente na qualidade dos frutos (Galeano et al, 2016;Santos et al, 2019).…”

“…A circunferência obtida para os frutos se mostrou inversamente proporcional em relação ao comprimento, sendo mais Research, Society andDevelopment, v. 10, n. 13, e449101321520, 2021 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v10i13.21520 determinante quando se compara cultivares, embora, entre as capinas haja diferença, os valores não são decisivos no momento da venda. Valores similares foram encontrados por Barker et al (2018).…”

Performance of 'Vitória' pineapple in response to different types of shoots and ages of floral induction

“…The lower is the vigor of the plants at the time of floral induction, the lower will be the quality of fruit. In addition, the age of floral induction varies according to genotype and to the cultivation environment (Barker et al, 2018). For this reason, the ideal time to perform the floral induction should be identified to plan the control of the desirable harvesting season of fruit with market standard.…”
