“…In the 'Smooth Cayenne' pineapple, the ascorbic acid content was reduced in plants with N and K deficiency (Martins et al, 2009), while Dantas et al (2015) reported that nitrogen fertilization above 10 g plant -1 urea and 152 g plant -1 chicken manure, reduced the antioxidant activity of cv. Vitória, probably by the diminution of bioactive compounds like flavonoids and ascorbic acid.…”

The quality aspects of pineapple infructescences are influenced by nutritional management. Thus, the objective was to evaluate the physical-chemical characteristics of the infructescences of cv. Imperial, submitted to fertilization with nitrogen (N) and potassium (K). The experimental design was a randomized complete block design with three replicates and the treatments were arranged in a factorial scheme according to the Plan Plueba III matrix, which consisted of a combination of five doses of N: 15; 90; 150; 210 and 285 kg ha Key words: Ananas comosus L. var. comosus; mineral fertilization; post-harvest Qualidade de infrutescências de abacaxizeiro 'Imperial', em função da adubação nitrogenada e potássica RESUMO: Os aspectos de qualidade das infrutescências de abacaxizeiro são influenciados pelo manejo nutricional. Assim, o trabalho foi realizado com o objetivo de avaliar as características físico-químicas das infrutescências de abacaxizeiro cv. Imperial, submetidos à adubação com nitrogênio (N) e potássio (K). O delineamento experimental foi casualizado em blocos, com três repetições e os tratamentos foram dispostos em esquema fatorial conforme a matriz Plan Plueba III, que consistiram na combinação de cinco doses de N: 15; 90; 150; 210 e 285 kg ha -1 e cinco doses de K: 21,6; 129,6; 216,0; 302,4 e 410,4 kg ha -1 . As características mensuradas nas infrutescências foram massa fresca; comprimento; diâmetro; firmeza; rendimento da polpa e da coroa; coloração da casca e da polpa; sólidos solúveis (SS); acidez titulável (AT); relação SS/AT e ácido ascórbico. A elevação das doses de K 2 O para 410,4 kg ha -1 aumentou a massa da infrutescência com coroa, comprimento e diâmetro da infrutescência e o teor de sólidos solúveis, colhendo-se nas plantas que receberam esta adubação, infrutescência com os tamanhos médios de 632,34 g, 9,0 cm, 84,80 mm e 16,42%, respectivamente. As plantas que receberam doses de N de 285 kg ha -1 favoreceram o rendimento da polpa, o índice de coloração a* e b* da casca e a relação SS/AT proporcionando valores médios de 44,50%, 9,64, 33,06 e 30,10, respectivamente. As doses de 285 kg ha -1 de N e 410,4 kg ha -1 de K 2 O promoveram melhorias nas características físico-químicas de infrutescências do abacaxizeiro 'Imperial'.

“…Fruit formation results from complex biological processes which begin soon after fertilization (Forlani et al, 2019) and involves a dynamic interplay between phytohormones (McAtee et al, 2013) and availability of essential nutrients (Dantas et al, 2015). These processes include cell division and expansion, accumulation of secondary metabolites, and an increase in carbohydrate biosynthesis (Forlani et al, 2019).…”

Pineapple (Ananas comosus vr. Comosus) plants require balanced nutrition to meet fruit’s market quality standards for consumption. The objective of this research was to evaluate the effects of organic and mineral fertilization on the development of the ‘Pérola’ pineapple infructescence produced in Paraíba State, Brazil. The plants were conducted under organic fertilization composed by a mixing of cattle manure and poultry litter n at 0, 50, 75 and 100% of the nitrogen doses recommended (NDR) for pineapple cultivation and mineral fertilization. The evaluation for fresh fruit length, diameter, mass, and crown length was initiated at the 43rd day after the floral induction (DAFI). The use organic fertilizer at 75 and 100% of the NDR provided a higher growth rate of fruits. In general, the length and diameter of the infructescences evolved rapidly until the 73rd DAFI, characterizing the first development phase. At the second phase, it was observed an intense growth rate to about the 103rd DAFI be reached, which was followed by a slower growth rate until around the 118th DAFI. In the third and last phase, from the 118th DAFI the physiological maturity of the fruit was reached and was characterized by the pineapple commercial maturation up to 133rd DAFI, with a quarter of the fruit yellow. Under the experimental conditions, the mixed fertilization in the level of 75% NDR, promoted a greater length and fresh mass than the conventional mineral fertilization for ‘Pérola’ pineapple and can be an alternative for this crop’ family farming production.

Soluble solids were determined in the homogenized pulp, through direct Reading at 20 o C, using a portable digital refractometer (Milwaukee, model -MA871: 0 -85%), with the results expressed as a percentage (DANTAS et al, 2015). The spectrophotometric browning index (OD 420 .g -1 ) of the core was obtained according to Raimbault et al (2011).…”

“…The pineapple plant is native to Uruguay, Brazil, and Paraguay, and is the most important of the commercially cultivated Bromeliaceae in the tropics and parts of the subtopics (TFnet, 2016) for ornamental purposes (SILVA et al, 2019), but mainly as a fruit of widespread worldwide consumption and trade (SANGPRAYOON et al, 2019). Its infructescence, the pineapple, is highly appreciated for its aroma and fl avor, and is recognized for having nutrients that provide energy to the usual diet and exert powerful biological activities which provide health benefi ts (DANTAS et al, 2015).…”

“…Brazil has stood out as the second largest pineapple producer in the world with production of 2,694,555 ton/ha in a production area of 68,699 ha; the Northeast region is responsible for 40% of production and yield (FAO, 2021), and the state of Paraíba is currently the second largest producer in the country (IBGE, 2020), with 'Pérola' pineapple being the main cultivar (DANTAS et al, 2015). Growing production opens up challenges to reach competitive export markets, demanding development of technologies which ensure maintenance of high quality standards (GUIMARÃES et al, 2017).…”

The pineapple, the most important fruit in the state of Paraíba, is characterized as an important generator of employment, income and regional development. With the increase in production, challenges arise in reaching distant competitive markets, including exports, making refrigerated storage necessary. However, pineapple, a tropical fruit, is subject to Chilling Injury (CI) when stored under sub-optimal temperatures, below 12 o C, which provide internal browning (IB) and quality loss. The use of pulsed electric fi eld (PEF), a non-thermal technology, can be an alternative in ensuring the control of IB in pineapple. Therefore, the objective of this work was to evaluate the infl uence of PEF application on IB, enzyme expression and activity, bioactive compounds and antioxidant activity of 'Pérola' pineapple. Initially, to defi ne the best strategy, 8 kV/cm of PEF was applied to pineapples directly and indirectly (drinking water), in 4 levels of electrical pulses: 0 (control), 5, 20 and 35, proving to be the most effi cient the indirect pulses. From these results, a completely randomized design was used, with indirect application of PEF at the four levels in pineapples, with 5 periods of evaluations at refrigeration at 5 o C, followed by transferring at each period for two more days to the room condition, in 4 replicants (3 fruit / rep). The indirect application of 35 pulses provided a reduction in expression and enzyme activity, IB and maintained the functional potential, being a promising alternative for the storage of pineapple under sub-optimal temperatures.
