“…The highest values of this variable were 12.07 and 12.84 cm, observed in experiments with bagana and black plastic, respectively, in plants exposed to the highest doses of FTE-12 and leaf fertilization (Figure 2). These fruit diameter values are similar to those found by Ventura et al (2009) in the state of Espírito Santo and higher than those reported by Silva et al (2010) in Paraíba State.…”

“…The highest fruit weights observed in this study were 1.26 and 1.31 kg for plants at the highest doses of FTE-12 and leaf fertilization in the experiment with bagana and black plastic, respectively (Figure 1). These results are lower than those observed by Ventura et al (2009), who found an average weight of 1.5 kg for the 'Vitória' pineapple grown in the state of Espírito Santo. On the other hand, Silva et al (2010) found a maximum weight of 1.0 kg for 'Vitória' pineapples grown with a dose of 409.2 kg N ha -1 in the state of Paraíba.…”

-The objective of this study was to evaluate the effects of foundation and leaf fertilization with micronutrients on fruit size and quality of pineapple cv. Vitória under the environmental conditions of the Baixo Acaraú irrigated perimeter in Northern Ceará State, Brazil, under two covers (bagana and black plastic) of the sandy soil of low fertility. The experimental design was a randomized split blocks one with four levels of soil dressing and four levels of foliar fertilization, with five replications. Micronutrient soil dressing was studied as FTE-12 at doses of 0, 60, 120 and 180 kg ha -1 . The four levels of foliar fertilization were: LF0 (without fertilizer), LF 1 (15 leaf fertilization, using the amount of 1158.75 g Fe ha -1 , 844.65 g Mn ha -1 , 391.5 g ha -1 Zn, 322.65 g ha -1 Cu and 216 g ha -1 B), LF2 (15 leaf fertilization, using twice the quantities of level LF1) and LF3 (15 leaf fertilization, using three times the amount of level LF1). At 13 months after planting the micropropagated plantlets was carried out the floral induction treatment and five months later the fruit harvest determining the following variables: fruit weight and median diameter, soluble solids content (SS) and titratable acidity (TA). Both fruit weight and diameter increased with increasing doses of micronutrients applied to the soil and to the leaves, of plants grown both on bagana soil cover and plastic mulch. On the other hand fruit pulp quality was little affected by the treatments studied. There were a small increase of SS contents for plants grown on bagana soil cover and a small decrease of titratable acidity for those grown on plastic mulch, in both cases just in response to micronutrient foliar application. Index terms: Ananas comosus comosus, fertilization, soluble solids, titratable acidity. QUALIDADE DO FRUTO DE ABACAXI 'VITORIA' SOB ADUBAÇÃORESUMO -Este trabalho teve como objetivo avaliar os efeitos da adubação de fundação e foliar com micronutrientes sobre aspectos físicos e qualitativos do abacaxi cv. Vitória, nas condições do Perímetro Irrigado Baixo Acaraú, norte do Estado do Ceará, sob duas coberturas do solo (bagana e plástico preto) arenoso e de baixa fertilidade. O delineamento experimental utilizado foi em blocos casualizados, em parcelas subdivididas, com quatro doses de adubação de fundação, e quatro níveis de adubação foliar, com cinco repetições. Para a adubação de fundação foi utilizado FTE-12 nas doses de 0; 60; 120 e 180 kg ha -1 . Os quatro níveis de adubação foliar foram: AF0 (sem adubação); AF1 (15 adubações foliares, usando um total de 1.158,75 g ha -1 de Fe, 844,65 g ha -1 de Mn, 391,5 g ha -1 de Zn, 322,65 g ha -1 de Cu e 216 g ha -1 de B); AF2 (15 adubações foliares, usando o dobro das quantidades do nível AF1), e AF3 (15 adubações foliares, usando o triplo das quantidades do nível AF1). Aos 13 meses após o plantio das mudas obtidas por micropropagação, foi realizado o tratamento de indução floral, e cinco meses mais tarde, a colheita, determinando-se as seguintes variáveis dos frutos...

An adequate mineral nutrition is essential for the development and productivity of pineapple. However, little is known about the nutritional and metabolic changes that occur in this crop in response to micronutrient deficiency or excess, particularly on tropical conditions. Thus, the objective of this study was to evaluate the application effects of micronutrients in soil and in leaf on biochemical responses of leaves during the development cycle of the pineapple crop. Samples were collected at 3, 6, 9, 12, and 17 months after transplantation. Leaf soluble carbohydrates and N-aminosoluble compounds were determined, as well as variations in the titratable acidity and pH. The soil and leaf micronutrient application increased the concentrations of carbohydrates and N-aminosoluble and reduced the leaf pH, and the changes were more significant in the last sampling (17 months after transplantation). Reductions in concentrations of carbohydrates and increase in the titratable acidity of the pineapple leaves collected at the end of the night were also observed, a fact that reflects the metabolism of Crassulacean acid metabolism species. The strategy of micronutrient application contributes positively to alter the metabolism of plants of pineapple cv. Victoria, especially during flowering and fruit development.
