Abstract
There are only a few strawberry cultivars available in Brazil and all are imported from North America and Europe. Thus, the introduction of new materials and their evaluation under Brazilian environmental conditions is imperative. The objective of this study was to evaluate the production, chemical components, and concentration of bioactive compounds in strawberry cultivars under edaphoclimatic conditions in the municipality of Pelotas-RS. The experiment was conducted in the field with low tunnels in 2011 and 2012. The experiment in the field was arranged in a completely randomized design, with eight treatments (cultivars), four replications. Each plot consisted of nine plants. The experiment in laboratory was arranged in a completely randomized 8x3 factorial design (8 cultivars and 3 months of harvest) and 4 replications. The variables analyzed were fruit number and fruit mass per plant, production, yield, soluble solid content, titratable acidity, ascorbic acid, anthocyanins, phenolic compounds, and antioxidant activity. Cultivar and harvest month influenced acidity, and the contents of soluble solids, ascorbic acid, and bioactive compounds. Cultivar Camarosa showed higher production, and higher contents of anthocyanin, phenolic compounds, and soluble solids. Cultivars ‘Palomar and ‘Aromas’ stand out for the content of ascorbic acid.
Highlights
According to estimates made by FAO, Brazil is not among the world’s leading strawberry producers: an area of only 400 hectares is reported and annual production of 3,390 tons (FAOSTAT 2019)
The strawberry cultivation is an activity of considerable economic importance because of its high profitability per area
This study aimed to evaluate production, physicochemical quality, and content of bioactive compounds in strawberry cultivars produced under the edaphoclimatic conditions in Pelotas-RS
Summary
According to estimates made by FAO, Brazil is not among the world’s leading strawberry producers: an area of only 400 hectares is reported and annual production of 3,390 tons (FAOSTAT 2019).The domestic strawberry production is almost all directed to the fresh fruit market (98%) (ANTUNES; PERES, 2013); it is still insufficient to supply the internal market due to the growing annual consumption. According to estimates made by FAO, Brazil is not among the world’s leading strawberry producers: an area of only 400 hectares is reported and annual production of 3,390 tons (FAOSTAT 2019). The strawberry cultivation is an activity of considerable economic importance because of its high profitability per area. The choice of cultivars is one of the factors that largely determine the success of strawberry cultivation. Cultivars must be adapted to the edaphoclimatic characteristics of each region, especially temperature and photoperiod (DUARTE FILHO et al, 2007). Flowering and fruit setting of strawberry are decisively influenced by climatic conditions, cultural practices, and genetic characteristics of the cultivars. A highyielding cultivar in a certain region may not adapt to another environment and not result in high yields (PEREIRA et al, 2013)
