Composition of the acerola of different genotypes in two seasons of harvest
MetadataShow full item record
The physical and chemical attributes of acerola can be influenced by several factors: genotype, orchard location, crop management, pluviometric index, irrigation, exposure to sunlight, fruit maturation stage and harvest season. The present work evaluated the chemical and physical-chemical characteristics of the acerola of different genotypes at two harvest seasons. The first time in the period from February to March 2014, and the second time from December 2014 to January 2015. The genetic materials evaluated were Olivier, BRS 237 - Roxinha, BRS 236 - Cherry, BRS 238 - Frutacor, BRS 235 - Apodi, Waldy - CATI 30 and Okinawa. The design was a completely randomized design in a factorial scheme, with 7 cultivars in 2 seasons of harvest, totaling 14 treatments, and the repetition being 500 g per sample of mature fruits for each genotype of acerola represented by eight plants in production and eight years of age. The following physico-chemical attributes were evaluated: pH and soluble solids (degrees Brix), and chemicals: ascorbic acid, and titratable acidity (expressed in g of citric acid 100 g(-1) of pulp). The ratio degrees Brix / Titratable acidity was also determined. In the two evaluated harvest periods, the composition of the acerola is more influenced by the genotype than by the climatic conditions of precipitation and temperature of the environment. All clones of acerola are in compliance with the Brazilian legislation in force regarding the quality of fruit pulp of acerola.
