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.
Na produção e na qualidade dos frutos do abacaxizeiro, a escolha adequada do tipo de propágulo a ser utilizado, em conjunto com o manejo das idades para a indução floral, são fatores importantes para que seja alcançado o máximo de características desejáveis que definirão o sucesso na produção da fruteira e sua boa aceitação no mercado. Objetivou-se, com este trabalho, avaliar a qualidade pós-colheita de frutos desenvolvidos de diferentes tipos de mudas e idades de indução floral do abacaxizeiro ?Vitória?. O experimento foi conduzido em delineamento de blocos ao acaso, em parcelas subdivididas, com quatro repetições, sendo as parcelas formadas pelos tipos de mudas (filhote e rebentão), e as subparcelas, compostas pelas diferentes idades da planta para indução floral (8, 10 e 12 meses após o plantio, e o florescimento natural). Foram realizadas avaliações das características de biomassa dos frutos com e sem coroa, circunferência, comprimento, diâmetro, firmeza, translucidez, coloração da polpa e qualidade físico-química. Não foi observada interação significativa para as variáveis biométricas e de biomassa, sendo que o tipo de muda influenciou apenas na biomassa da coroa e no diâmetro do cilindro central, que foram superiores nas mudas-filhote. Para os atributos cor, área translúcida e firmeza, também não houve interação e foram influenciados apenas pelas idades de indução, exceto para a variável de cor referente à intensidade das cores verde e vermelha. Independentemente dos tipos de mudas estudados, nas condições ambientais de plantio realizado em abril de 2015, os frutos originados de induções aos 12 meses e natural apresentaram maior firmeza, característica desejável na exportação e na industrialização, principalmente na fabricação de fatias de abacaxi, pedaços em calda e cristalizados. Mudas do tipo filhote, induzidas aos 12 meses e naturalmente, proporcionaram frutos com relação superior entre sólidos solúveis e acidez.

The ability to avoid self-pollination is a trait that evolved as a manner of reducing the deleterious effects of inbreeding in various allogamous plant species, including Coffea canephora. The aim of this study was to perform directed hybridizations to characterize the compatibility groups of superior C. canephora clones, since plant selection can reduce variability for this trait. For that purpose, directed hybridizations were carried out in cross arrangements using a balanced diallel without self-fertilization and without reciprocals. The genotypes evaluated were derived from open pollination and from directed hybridizations using Encapa03 as a male parent donor of pollen grains and Robusta640, Robusta 2258, and Robusta1675 as female parent receptors of pollen grains. To control the occurrence of type I and type II errors, the likelihood ratio test was used. Compatible crosses were predominant (73.7%). Compatible crosses exhibited a mean rate of fruit set of 44%, with amplitude from 26% to 77%. Of the total of 80 crosses performed, three crosses exhibited unexpected results according to the grouping proposed (P08 x P16, P09 x P15, P09 x P16). From the degree of kinship, the genealogy of the S gene and the segregation of the alleles from one generation to another was estimated. The genotypes P12, P14, and P10 exhibited the highest estimates of LOD score associated with their clustering in groups I, II, and III. These genotypes may be used as tester plants of their compatibility groups MenosThe ability to avoid self-pollination is a trait that evolved as a manner of reducing the deleterious effects of inbreeding in various allogamous plant species, including Coffea canephora.
