“…* Significant at 5% probability by F test. MAPA, 2002;Vilela et al, 2015). It is necessary to emphasize that the average mass of infructescences of plants coming from in vitro culture, in the first cycle, is smaller since they tend to present fewer reserves and slower growth.…”

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'.

“…According to Ceagesp (2003), pineapple fruit must have at least from 900 to 1,200 g for domestic fresh consumption, and 700 to 2,300 g for export. However, fruit with lower mass can be processed for juice or candy industries (Vilela et al, 2015).…”

The objective of this work was to evaluate the effect of shoot types and plant ages for floral induction on the performance of 'Vitória' pineapple (Ananas comosus). The experiment was carried out from April 2015 to December 2016, using shoots of two different classifications (slips of 100 to 200 g and suckers of 201 to 300 g). Artificial floral induction was performed at the eighth, tenth, and twelfth months after planting, and natural induction was also evaluated. Evaluations for vegetative development, phenology, and productivity were performed. A significant interaction was observed between the studied factors for width and area of the “D” leaf. Shoot type did not influence productivity. Natural flowering extended the crop cycle by 617 days. The induction performed at the eighth month anticipated harvest by up to 167 days. Earlier inductions reduced productivity by 58.15% due to the reduction of fruit mass. Naturally induced plants produced larger fruit ranging from 1.0 to 1.2 kg. Inductions from the eighth to the tenth month promote harvesting in more favorable seasons.

“…Imperial, Sampaio et al (2011) obtained a mass of 34 g at 14 months after planting, corresponding to the mass of the fruit with 670 g crown. Vilela et al (2015) recommended doing floral induction in cv. Vitória, when the fresh mass of leaf D is equal or greater than 70 g or diameter of the minimum stem of 8.5 cm, with a fruit mass equal or greater than 1.2 kg plant -1 .…”

“…In this sense, in pineapple, the length and fresh mass of leaf D have been used as parameters to estimate plant maturity and productivity in cultivars already established in the market, such as 'Pérola' and 'Smooth Cayenne' (Rodrigues et al, 2010;Marques et al, 2011). Vilela et al (2015) recommends doing the floral induction in cv. Vitória, when the fresh matter mass of leaf D is around 70 g, aiming at fresh fruit mass equal or greater than 1.2 kg plant -1 .…”

The cv. Imperial has great commercial potential. Its expansion depends, to a large extent, on the adjustment to the fertilization recommendations proposed in the fertilization and liming recommendation bulletins of the main producing states, in order to have adequate nutritional management. The objective of this study was to verify the growth of leaf D and the productivity of 'Imperial' pineapple cultivated under the presence and levels of fertilization of N and K. The experimental design was a randomized complete block with three replicates and treatments were arranged in a factorial scheme according to the Plan Plueba III matrix, with five doses of N (15; 90; 150; 210 and 285 kg ha -1 ) and five doses of K (21.6, 129.6, 216.0, 302.4 and 410.4 kg ha -1 ). Data were submitted to analysis of variance. To evaluate the effect of the interaction of N and K doses and days after planting, the response surface technique was used.
