Os experimentos foram conduzidos na fazenda Mape Frutas Ltda, localizada em Datas-MG, e no laborat?rio de Tecnologia de Biomassa do Cerrado, da UFVJM. Foram avaliadas oito cultivares de morangueiro: seis de dias curtos (Festival, Campinas, Toyonoka, Dover, Oso Grande e Camarosa), e duas de dias neutros (Diamante, Aromas), utilizando-se delineamentos estat?sticos espec?ficos para cada experimento. Os frutos foram colhidos duas vezes por semana no per?odo de maio a outubro de 2012. A cultivar Dover foi a que produziu maior n?mero de mudas por matriz e maior n?mero de mudas por hectare. As cultivares Aromas e Diamante apresentaram as maiores produtividades precoces de frutos. N?o foram observadas diferen?as significativas entre as cultivares para a produ??o por planta e para a produtividade total de frutos, exceto para a cultivar Toyonoka que apresentou os menores valores para essas caracter?sticas. As cultivares Camarosa, Diamante, Festival e Oso Grande apresentaram as maiores produ??es comerciais por planta e as maiores produtividades comerciais de frutos. As maiores produtividades totais foram obtidas nos meses de junho, julho e setembro. J?s as maiores produtividades comerciais foram obtidas no m?s de junho. As cultivares Camarosa, Festival e Toyonoka apresentaram as melhores caracter?sticas f?sico-qu?micas e antioxidantes. A cultivar Toyonoka apresentou a menor quantidade de aer?bicos mes?filos totais e a cultivar Oso Grande a menor quantidade de bolores e leveduras. Os frutos colhidos no m?s de outubro apresentaram maiores teores de a??cares redutores totais, vitamina C, fen?licos, antocianina, caroten?ides, s?lidos sol?veis e atividade antioxidante. A perda de massa dos frutos ? maior em condi??es de armazenamento ambiente quando comparado com o armazenamento em c?mara fria. O armazenamento em c?mara fria proporciona maior conserva??o p?s-colheita de frutos de morangueiro. Em condi??o ambiente os frutos podem ser armazenados por no m?ximo tr?s dias. J? em c?mara fria o armazenamento de frutos de morangueiro pode se prolongar por at? doze dias. A cultivar Toyonoka apesar de apresentar as melhores caracter?sticas f?sico-qu?micas, apresenta, juntamente com a cultivar Campinas, maiores incid?ncia de doen?as, maior perda de massa e menor firmeza dos frutos em rela??o as demais cultivares, havendo necessidade de ado??o de outras pr?ticas de conserva??o dos frutos. A perda de massa e a incid?ncia de doen?as afetam negativamente a apar?ncia dos frutos de morangueiro durante o armazenamento em c?mara fria, enquanto que em condi??o ambiente a incid?ncia de doen?as diminui a qualidade da apar?ncia dos frutos de morangueiro.Disserta??o (Mestrado) ?

The experiments were conducted on the Mape Fruits Farm Ltda, located in Datas - MG, in the Laboratory of Biomass Technology of the Cerrado, in the UFVJM. We assessed eight strawberry cultivars: six short days (Festival, Campinas, Toyonoka, Dover, Oso Grande and Camarosa), and two neutral days (Diamante, Aromas), using statistical designs specific to each experiment. The fruits were harvested twice a week from May to October 2012. Cultivar Dover was the one that produced the largest number of seedlings per array and larger number of seedlings per hectare. The Aromas and Diamante showed greater yield early fruit. There were significant differences among cultivars for plant production and overall productivity of fruits, except for the cultivar Toyonoka presented the lowest values ??for these features. The cultivars Camarosa, Diamante, Oso Grande Festival and had the highest yields per plant and commercial greatest commercial yields of fruit. The highest total productivities were obtained in the months of June, July and September. The greatest commercial yields were obtained in June. The cultivars Camarosa, Festival and Toyonoka showed the best physical and chemical characteristics and antioxidants properties. Cultivar Toyonoka had the lowest amount of aerobic mesophilic and Oso Grande cultivated the least amount of mold and yeast. Fruit harvested in October showed higher levels of total reducing sugars, vitamin C, phenolics, anthocyanin, carotenoids, antioxidant activity and soluble solids. The mass loss of the fruits is increased in ambient storage conditions when compared to cold storage. The cold storage provides greater post-harvest conservation of strawberry fruits. In natural conditions the fruits can be stored for a maximum of three days. Already in cold storage of strawberry fruits can be extended for up to twelve days. Cultivar Toyonoka despite having the best physical and chemical characteristics, features coupled with the variety Campinas, higher incidence of disease, greater weight loss and lower fruit firmness compared with other cultivars, requiring adoption of other conservation practices fruits. The weight loss and the incidence of diseases negatively affect the appearance of the fruit of strawberry during storage in a cold chamber at ambient condition while the incidence of disease decreases the quality of the appearance of the fruit of strawberry
