Abstract

EXPLORATORY ANALYSIS OF MORPHOLOGICAL AND QUALITATIVE CHARACTERISTICS OF ORANGE VARIETIES IN BREJÃO-EP COLLECTIONABSTRACT -Studies on citrus table fruits still has little expression in the country. This study aimed to analyze the morphological and the physical, physico-chemical and chemical characteristics of plants and fruits of 15 varieties of oranges, courtesy of the National Research Center for Cassava and Fruit (Embrapa -CNPMF), and planted at the Experimental Station of the Agronomic Institute of Pernambuco, Brejão-PE. It was evaluated: stem diameter above and below the graft and the relationship between them, crown diameter, plant height and canopy volume. In fruits evaluations consisted of: format, epicarp color, fruit weight and height, juice weight, , fruit diameter, thickness of mesocarp and endocarp, number of seeds per fruit and juice yield. The experimental design was randomized blocks with four replications and one plant per plot. For the qualitative aspect of the fruits it was used the same design, they were evaluated by 12 descriptors. Only six of the studied varieties of oranges are within the requirements of the Brazilian Program for the Modernization of Horticulture and five varieties of oranges showed different maturation from those described in the literature

Performance of ‘Tuxpan Valencia’ Sweet Orange Grafted Onto 14 Rootstocks in Northern Bahia, Brazil

“…The average fruit quality attributes of 'Tuxpan Valencia' orange observed in Rio Real-BA (Table 3) were similar to those described for this variety in studies in Cordeirópolis-SP and Brejão-PE, in which the fruits were typically late and with weight exceeding 150 g (BLUMER et al, 2003;MEDEIROS et al, 2013.). The 'Tuxpan Valencia' orange assessed in the present conditions of the northern coast of Bahia presented physical and chemical characteristics of fruits suitable for processing or fresh fruit market, as the usual market requirements (NONINO, 1995;CEAGESP, 2011).…”

Initial performance of alternative citrus scion and rootstock combinations on the northern coast of the state of Bahia, Brazil

“…'Pineapple' was highlighted for its high production in the State of Sergipe (Carvalho et al, 2015b). Medeiros et al (2013), assessing the qualitative characteristics of 15 sweet orange varieties in the State of Pernambuco, Brazil, classified Pineapple, Salustiana, and Sunstar cultivars as maturation in mid-season. These results are in accordance with the maturity order observed in the present study, in relation to the maturity index (Table 2).…”

“…As características climáticas e a variedade do solo brasileiro o tornam favoráveis para a produção de laranja no país, o que tornou o Brasil um mercado relevante mundialmente, quando se trata de produção e exportação da laranja e dos seus derivados (Medeiros et al, 2013).…”
