Produção e qualidade físico-química de morangos de três cultivares produzidos em Saudade do Iguaçu - PR

Abstract

The success of the strawberry crop production (Fragaria ananassa Duch.) is influence by several aspects such as place edaphoclimatic conditions, techniques of the production, management and varieties. The lack of studies in the regions of the Southwest of Paraná, regarding which cultivar adequately adapts to the growing conditions is a limiting agent to obtain a guarantee of income from this crop. Therefore, it’s necessary to know which is the best variety, taking into account it’s yield per cycle and the physical chemistry quality of it’s fruits. The experiment was carried out in strawberry beds, using ground cover and a low tunnel system, through conventional cultivation, in the city of Saudade do Iguaçu - PR. During the production cycle, fresh matter mass, number, polar and equatorial diameters and fruit shape were formed in the field, as well as production. In the laboratory evaluated the soluble solids, total acidity (TA), SST / AT ratio, color parameters, firmness and pH of strawberries. Three cultivars: Portola®, Monterey® and Fronteras® were evaluated in two seasons (September and October). The cultivars do not dissipate regarding the ratio. Portola® showed greater firmness and parameters related to the color of its fruits, as well as, together with Fronteras®, greater production. Monterey® produced fruits of greater mass and size.
