“…The results of this work demonstrate its importance, since the need to research more about the effect of mineral elements on the quality of the fruits of pineapple, results agree with Aular et al (2014) repots, which claim that the N can affect or not the fruit mass, SS and TA; and K may affect or not fruit size, SS, TA and SS/AT.…”

The aim of this paper is to evaluate the yield and quality of 'Pérola' pineapple under increasing rates of nitrogen and potassium applied through fertigation. The experiment was conducted in a randomized block design, with four replications, in a factorial scheme (4x4), which represents four nitrogen rates (128, 256, 384 and 512 kg ha-1 of N) and four potassium rates (192, 384, 576 and 768 kg ha-1of K2O) via fertigation. The evaluations consisted of physical and chemical fruit characteristics and yield. Increasing nitrogen rates provided linear growth on fruit production features and the rate of 516 kg ha-1 resulted in fruits with the largest diameters. The highest total yield on 'Pérola' pineapple crop was reached on plants under the supply of 498 kg ha-1 of K2O. Rates between 523 and 583 kg ha-1 of K2O, provided the largest fruit matter and the highest fruit pulp yield. The increasing amount of nitrogen applied by fertigation resulted in linear growth on fruit pulp pH, though it did not influence the soluble solids content. The lower acid content and higher SS/acid ratio on fruits were reached with the N rates of 333 and 375 kg ha-1 respectively.

“…However, the pulp pH declined linearly as N rates were increased. Aular et al (2014) observed that the response of 'Smooth Cayenne' pineapple to sources and levels of potassium on quality (fruit size, TSS, total titratable acidity [TTA], and TSS/TTA ratio) was positive to K and negative to N (fruit weight, TSS, and TTA). Total titratable acidity increased in response to K application, especially with the use of KCl.…”

Relationship Between Yield and Fruit Quality of Passion Fruit C03 Progenies Under Different Nutritional Levels

et al. 2017

-The present study was conducted to evaluate different fertilization-management strategies in ten progenies of passion fruit from the third recurrent selection cycle and their effects on yield and fruitquality traits. For this purpose, we adopted the strategy of correlations analysis, using the phenotypic and path correlations in different environmental conditions characterized by three levels of fertilization. The trial was set up as a randomized-block design in a split-plot arrangement with progenies representing the plots and three levels of potassium-nitrogen fertilization as the sub-plots, with three replicates. Path analysis showed that number of fruits was the variable of highest correlation with fruit diameter at fertilization I. Fruit weight and pulp weight were correlated with each other and with other traits like fruit length and fruit diameter at the three fertilization levels, except for number of fruits, which was correlated with nitrogen and potassium only at fertilization II. Path analysis also revealed that fruit diameter (3.125) showed the highest direct effect on yield at fertilization I. However, fruit weight and number of fruits showed, at fertilization II, the highest direct effects of 2.964 and 1.134 on yield, respectively, and number of fruits had a high phenotypic correlation and direct effect on yield at the three fertilization levels: 0.528 at fertilization I; 2.206 at fertilization II; and 0.928 at fertilization III. The results demonstrate the greater direct effect obtained with fertilization II, suggesting that the level adopted at fertilization II can provide satisfactory gains in yield and is thus recommended for the population in question.

RELAÇÃO ENTRE PRODUTIVIDADE E QUALIDADE DE FRUTOS DE PROGÊNIES C 03 DE MARACUJÁ-AZEDO SOB DIFERENTES NÍVEIS NUTRICIONAISRESUMO-O presente trabalho foi desenvolvido com a finalidade de avaliar diferentes manejos de adubação em dez progênies de maracujazeiro-azedo do terceiro ciclo de seleção recorrente e seus efeitos sobre variáveis de produção e qualidade de frutos. Para isso lançou-se mão da estratégia da análise de correlações via correlações fenotípicas e de trilha, em diferentes condições de ambiente caracterizados por três níveis de adubação. O ensaio foi montado em delineamento de blocos ao acaso num esquema de parcelas subdivididas com as progênies nas parcelas e os três níveis de adubação potássica e nitrogenada nas subparcelas, com três repetições. Observou-se através da análise de trilha que a variável número de frutos foi a que apresentou a correlação de maior magnitude com o diâmetro do fruto na adubação I, entretanto o peso do fruto e o peso da polpa correlacionaram-se entre si e com outras variáveis como o comprimento e diâmetro dos frutos nos três níveis de adubação, exceto o número de frutos que correlacionou com a variável nitrogênio e potássio apenas na adubação II. A análise de trilha, também mostrou que a variável diâmetro do fruto (3...

“…As examples, there is the study made by Fallahi et al (2010) on apple; or the study conducted about some tropical fruits, such as banana, mango, guava and papaya, by Aular & Natale (2013); or the study conducted about passion fruit and pineapple by Aular et al (2014). In the study on apple, it was shown how some mineral elements can affect fruit quality, what cannot be fully affirmed for tropical fruits, for which further research is recommended.…”

There are some reviews, available in the literature that considers mineral elements effects on fruit quality. However, most studies refer to temperate fruits, such as apple, or to some tropical fruits, such as mango, guava, banana, pineapple and passion fruit. In the case of citrus fruits, it is necessary to compile the information that has been generated recently. The objective of this review was to present and comment some information about the influence of mineral elements on citrus fruit characteristics. It emphasized that potassium has been the most evaluated macronutrient, whereas calcium and magnesium were the least. Potassium was the element with the largest influence on fruit characteristics, followed by nitrogen and phosphorus. The most consistent result related to potassium was the positive effect on fruit fresh mass. Zinc was the most evaluated micronutrient, followed by boron, which was the most influential micronutrient on quality, especially due to its positive effect on fruit fresh mass and juice percentage. Lack of information regarding mineral nutrition effect on citrus fruit quality was confirmed and was more evident for macronutrients. Additional keywords:Citrus; fruit production, nutrients. ResumoAlgumas revisões que considerem os efeitos dos elementos minerais na qualidade de frutas estão disponíveis na literatura; no entanto, a maioria faz referência às frutíferas de clima temperado, como a maçã ou algumas tropicais como manga, goiaba, banana, abacaxi e maracujá. No caso das frutas cítricas ou citros, pode-se argumentar que é necessário recopilar as informações que têm sido geradas recentemente. O objetivo desta revisão foi apresentar e comentar algumas informações sobre a influência de elementos minerais sobre as características das frutas destas frutíferas. Ressalta-se, que o potássio tem sido o macronutriente mais avaliado, enquanto que o cálcio e o magnésio foram os menos pesquisados. O potássio foi o elemento com maior influência nas características da fruta, seguido do nitrogênio e do fósforo. O resultado mais consistente do potássio foi o efeito positivo sobre a massa fresca da fruta. O zinco foi o micronutriente mais avaliado nos experimentos, seguido do boro que foi o micronutriente mais influente na qualidade, especialmente pelo seu efeito positivo sobre a massa fresca e a porcentagem de suco das frutas. Foi confirmada a carência de informações referentes ao efeito da nutrição mineral sobre a qualidade das frutas dos citros, sendo mais evidente para os macronutrientes.
