Quality of ‘Tahiti’ Acid Lime Fertilized With Nitrogen and Potassium in the Semiarid Region of Minas Gerais

Abstract

AbSTRACT-this study aimed to evaluate external characteristics and juice obtained from 'tahiti' acid lime produced under nitrogen and potassium fertilization. this study had a completely randomized design with three replicates of four fruits of the two central plants, 4 x 5 factorial and four N doses (0, 25, 50 ), totaling 20 treatments. In the postharvest period, external characteristics (size, color and skin thickness, firmness and fresh mass) and juice (content, percentage, soluble solids, technological index, pH, titratable acidity, ratio and ascorbic acid) of fruits were evaluated. Size, skin color, soluble solids content and pH of 'tahiti' acid lime juice were not affected by N and K 2 O fertilization. Skin thickness, juice percentage and technological index increased with the N and K 2 O doses applied to the soil. Juice content and fruit firmness decreased with application of K 2 O doses. titratable acidity and ascorbic acid content increased with K 2 O doses. the different nitrogen and potassium doses influenced more the juice quality than the external characteristics of 'Tahiti' acid lime in the postharvest period. Index Terms: Citrus latifolia tanaka, postharvest, size, color, juice. QUALIDADE DE LIMA ÁCIDA 'TAHITI' ADUbADA COM NITROGÊNIO E POTÁSSIO NO SEMIÁRIDO DE MINAS GERAISRESUMO-Objetivou-se avaliar as características externas e as do suco de lima-ácida 'tahiti', produzida sob adubação nitrogenada e potássica. utilizou-se o delineamento inteiramente casualizado, com três repetições de quatro frutos das duas plantas centrais, em esquema fatorial 4 x 5, sendo quatro doses de N (0; 25; 50 e 100 Kg. ha -1 . ano -1 ) e cinco doses de K2O (0; 25; 50; 100 e 200 kg. ha -1 . ano -1 ), totalizando 20 tratamentos. Em pós-colheita, avaliaram-se as características externas (tamanho, cor e espessura da casca, firmeza e massa fresca) e as do suco (volume, percentagem, sólidos solúveis, índice tecnológico, pH, acidez titulável, ratio e ácido ascórbico dos frutos). O tamanho, a cor da casca, o teor de sólidos solúveis e o pH do suco de lima ácida 'Tahiti' não foram influenciados pelas adubações com N e K 2 O. A espessura da casca, a porcentagem de suco e o índice tecnológico aumentaram com as doses de N e K 2 O aplicadas no solo. O volume de suco e a firmeza do fruto reduziram com as aplicações das doses de K 2 O. A acidez titulável e o teor de ácido ascórbico aumentaram com as doses de K 2 O. As diferentes doses de adubação nitrogenada e potássica influenciaram mais na qualidade do suco que nas características externas de lima-ácida 'Tahiti', em pós-colheita. Termos para Indexação: Citrus latifolia tanaka, pós-colheita, tamanho, cor, suco.1 .

Vegetative development and production of ‘Tahiti’ acid lime clone selections grafted on different rootstocks

“…According to classification suggested by Bleinroth (1995), 'Tahiti' fruits can be grouped into five categories according to their size as follows: 1-diameter 47-50 mm; 2-diameter 50-53 mm; 3-diameter 53-56 mm; 4-diameter 56-60 mm and 5 -diameter above 60 mm. Fruits from the different clones can be classified into caliber 2 and 3 for clones with lower values and 4 and 5 for higher values, meeting requirements of the foreign market, which require fruits with longitudinal diameter between 47 and 60 mm (CASTRICINI et al , 2017).…”

Repeatability coefficient estimates and optimum number of harvests in graft/rootstock combinations for 'tahiti' acid lime

“…The socioeconomic importance of citriculture as an area of fruit growing stands out in a worldwide scenario (Sales et al, 2018). From the genus Citrus, the species Citrus latifolia (Tanaka), which is popularly known as the 'Tahiti' acid lime, has shown commercial potential in the increasing the Brazilian internal consumer market (Castricini, Silva, Silva, & Rodrigues, 2017). This fruit is prominent in the citrus market due to its availability throughout the year, and nearly 50 thousand hectares of the crop exist in Brazil (Morais et al, 2020).…”
