Zusammenfassung: | 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, Brejao-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 Index terms: collection, development, analysis physical chemistry. Este trabalho teve como objetivo avaliar as caracteristicas morfologicas e os aspectos fisicos, fisico-quimicos e quimicos das plantas e dos frutos de 15 variedades de laranjas cedidas pelo Centro Nacional de Pesquisa de Mandioca e Fruticultura (Embrapa--CNPMF), e plantadas na Estacao Experimental do Instituto Agronomico de Pernambuco, Brejao-PE. Foram avaliados: diametro do caule acima e abaixo da linha de enxertia e a relacao entre eles, diametro da copa, altura da planta e volume de copa. Nos frutos, as avaliacoes consistiram em: formato, coloracao do epicarpo, massa do fruto, massa do suco, altura e diametro do fruto, espessura do mesocarpo e do endocarpo, numero de sementes por fruto e rendimento em suco. O delineamento experimental foi em blocos casualisados, com quatro repeticoes e uma planta por parcela. Para o aspecto qualitativo dos frutos, utilizou-se o mesmo delineamento, e foram avaliados atraves de 12 descritores. Apenas seis das variedades de laranjas estudadas estao dentro das exigencias do Programa Brasileiro para a Modernizacao da Horticultura e cinco das variedades de laranjas mostraram-se com maturacao diferente das descritas na literatura. Termos para indexacao: Colecao, desenvolvimento, analises fisico-quimica. |
