Resumo
O presente trabalho teve por objetivo, obter maiores informações sobre o desenvolvimento de quatro cultivares de morangueiro (Dover, Oso Grande, Camarosa e Sweet Charlie), na região de Bauru - SP, submetidos a sistemas fitossanitários alternativos, como ferramenta na Produção Integrada do Morangueiro (PIMO). Avaliou-se aspectos de produtividade (peso e número de frutos); qualidade (teor de sólidos solúveis totais, acidez titulável, pH, vitamina C e textura) e monitoramento de pragas e doenças. O plantio foi realizado em abril de 2005 sobre plástico preto, no espaçamento de 25 x 25 cm, totalizando-se 20 plantas por parcela. O delineamento estatístico foi em blocos casualizados utilizando-se um esquema fatorial em parcelas subdivididas, no qual o fator principal conteve dois modelos de tratamentos fitossanitários e para o fator secundário, as quatro cultivares de morangueiro. Nos dois modelos de tratamentos foram utilizados agroquímicos convencionais da grade PIF para Morango na fase vegetativa (abamectina e tebuconazol), diferenciando-se para a fase reprodutiva; Modelo PIF 1: tratamento com calda viçosa, super magro, Microgeo (2%) e enxofre e Modelo PIF 2: tratamento com calda bordalesa, super magro, éster de ácido graxo (GOC 109) (5%) e enxofre. Os dados obtidos foram submetidos à análise de variância e as médias comparadas através do Teste de Tukey a 5% de probabilidade. A cultivar Dover apresentou maior produtividade média e número médio de frutos independente do sistema de produção; textura mais firme e menor ratio (sabor) indicando maior aptidão para a indústria. A XI cultivar Oso Grande destacou-se positivamente na produção de frutos graúdos, firmeza e sabor, aspectos importantes para o consumidor e comercialização. Sweet Charlie apresentou excelente características de sabor e vitamina C...
The present work had for objective, to obtain more information about the development of four strawberry cultivars ( Dover, Oso Grande, Camarosa and Sweet Charlie), in Bauru - SP, submitted to alternative phytosanitary systems, as tool for the Integrated Strawberry Production. Aspects of productivity (weigh and number of fruits); quality (total soluble solids, titrable acidity, pH, vitamin C and firmness) and pest and disease monitoring were evaluated. The planting was accomplished in April of 2005 over mulching, the spacing of 25 x 25 cm was adopted being totaled 20 plants by plot. Experimental design used was of randomized blocks in factorial scheme of split plots with the main factor contained two models of phytosanitary treatment and for the secondary factor, the four strawberry cultivars. Conventional agrochemicals (abamectin and tebuconazol) registered for this culture in Brazil, were used for both models of treatment, in the vegetative phase. For the reproductive phase; Model PIF 1: treatment with Viçosa mixture, biofertilizer Supermagro, Microgeo (2%) and sulfur; and Model PIF 2: treatment with Bourdeaux mixture, biofertilizer Supermagro, fatty acid ester (GOC 109) (5%) and sulfur. The data were submitted to a variance analysis and the average compared to Tukey's Test at 5% of probability. 'Dover' presented larger medium productivity and medium number of fruits independent of the production system; firmer texture and smaller ratio (flavor) indicating larger aptitude for the industry. 'Oso Grande' stood out positively in the production of great fruits, firmness and flavor, important aspects for the consumer and commercialization. Sweet XIII Charlie' presented excellent flavor characteristics and vitamin C, demonstrating an aptitude for in natura consumption. There were not significant differences among the employed production... (Complete abstract click electronic access below)
