Comparative study of the mandarin hybrid fruit characteristics: Nova, Murcott and Ortanique in Capão Bonito SP, Brazil

Abstract

The Murcott tangor represent 20% of the tangerines trees in São Paulo State being the second more grown. Their fruits have good acceptance in the market cause of the good characteristics presented as: size, attractive internal and external color, transport resistance, high juice rate and industry potential. It is necessary to study the behavior of others varieties, in order to amplify the diversity of tangerine industry, which show suitable characteristics to the fresh fruit market and that make possible different harvest season. Many tangerine varieties, selected from the Citrus Germplasm Bank of the do Centro Avançado de Pesquisa Tecnológica do Agronegócio de Citros "Sylvio Moreira"/IAC, belong to trials carried out in 15 places in São Paulo State. The Capão Bonito area, south-west of the state, is one of this places where the Nova tangelo, the Ortanique and the Murcott tangors are showing quite good results about their fruit qualities. This paper had as an objective to compare the fruit characteristics of the Nova tangelo, the Murcott and the Ortanique tangors grafted on two rootstocks: Rangpur lime and Cleopatra mandarin. Accordingly to the gotten results, is possible to conclude that Nova and Ortanique had shown weight, width, fruit shape and juice percent, similar to the Murcott. In compliance with the harvest season, the Nova present suitable conditions to fresh fruit market in May and June. By the other hand the Murcott fruits can be harvested in July to August and the Ortanique in August to September. For this reason, is possible extend the harvest season of this mandarin-like, from two to five month, occurring inclusive in a period out of the crop at the north hemisphere.

Application of carnauba-based wax maintains postharvest quality of 'Ortanique' tangor

“…This difference, however, may not be of practical importance considering that the average values yielded by coated and uncoated fruits are very close. Taken as a whole, the percentage of juice, regardless of coating, observed in this study is lower than that reported by Borges and Pio (2003), 50.5% for 'Ortanique' grown in the south of the country. This difference between juice content might be due to many factors including climate and rootstock, which may play a direct role in fruit quality (McCOLLUN; BOWMAN, 2002).…”

“…As a leading world citrus producer, Brazil contributes approximately 28% of the world citrus production (TAZIMA et al, 2009), and although recent data on citrus planted areas (INSTITUTO…, 2008) may indicate that citrus production has been emerging nationwide, tangor production is concentrated mostly in the south, and São Paulo state has the largest planted area. According to Borges and Pio, (2003) despite being much appreciated all over the country, the quality of tangors produced in traditional growing areas in Brazil is not comparable to that observed on fruits produced elsewhere.…”

“…MORTON (1987) describes 'Ortanique' tangor as oblate in form; having thin and adherent peel; pulp divided into 16 segments with scant rag, very juicy; seedless or with few seeds; and of distinctive acid-sweet flavor. Subject to bruising when freshly picked, tangors need careful handling by harvesters and packers, as well as appropriate conditions to extend fruit quality after harvest (BORGES; PIO, 2003). As a leading world citrus producer, Brazil contributes approximately 28% of the world citrus production (TAZIMA et al, 2009), and although recent data on citrus planted areas (INSTITUTO…, 2008) may indicate that citrus production has been emerging nationwide, tangor production is concentrated mostly in the south, and São Paulo state has the largest planted area.…”

Qualidade e maturação de tangerinas e seus híbridos em São Paulo

“…Borges & Pio (2003) encontraram massa média superior à descrita na Espanha para a variedade Nova, o que também ocorreu neste trabalho.…”

Descascamento de frutas cítricas pelo uso do tratamento hidrotérmico

“…Para as frutas cítricas, a relação entre os teores de sólidos solúveis e de acidez titulável ("ratio") é uma característica essencial, porque auxilia na determinação do ponto ideal de colheita (BORGES; PIO, 2003). O "ratio" para laranjas pode variar entre 6 e 20, sendo ideal a faixa compreendida entre 11 e 16 (VIÉGAS, 1991).…”
