Resumo: |
The study of promising genotypes of crown and rootstock in potential regions for the production of fresh citrus fruits is fundamental to the continued development of national citrus sector. The microregion of Garanhuns in Southern Agreste of Pernambuco and other potential areas of northeast of Brazil, due to favorable edafoclimatic conditions for growing citrus, can generate production that could serve both regional and international markets. Thus, the objective was to evaluate genotypes of tangerines and grapefruits at Southern Agreste of Pernambuco conditions, through evaluation of agronomic parameters and physical, chemical and physical-chemical characteristics of fruits, aiming at the diversification of fruticulture. The experiment was conducted at Experimental Station of Brejão (IPA), evaluating thirteen varieties of tangerines and hybrids and three grapefruits. The evaluation of the maturation period was identified with the accompanying from development floral branch to maturation of fruits. For the analysis of plant development, was used the randomized block design with five replications and one plant per plot, being evaluated the diameter of stem above and below of grafting point, the crown diameter, plant height and volume crown. For the analysis of the fruits was used the randomized block design with four replications and four fruits per plot, being used twelve descriptors. In relation to maturation period, the Murcott, Kinnow and Fortune Iniasel tangerines were classified as mid-season, even as the Flame, Star Ruby and Henderson grapefruits. The Nova tangerine and the Flame grapefruit presented the smallest crown volume with 9.71 and 8.70 cubic meters respectively in the last measurement, positive feature in citrus breeding programs to obtain new crown varieties. Regarding fruit, the Robinson tangerine and the Henderson grapefruit presented the highest ratio mean with 20.83 and 5.93 respectively. All tangerines showed diameter within the established by standard classification of fresh citrus fruits, however, the Mexerica, Dancy and Swatow varieties had average fruit weight less than the main commercialized tangerines, even as the three grapefruits varieties studied. |
