Respuesta de tres variedades de rosa (Rosa spp.) a distintas concentraciones de biorreguladores de plantas en Biblián-Ecuador.”

Abstract

In Ecuador, the systems of production of flowers is an of the more important items of the PIB, occupying the third position as an exporter in the world of cut flowers, of which 73% are roses. In the crop of rose, the commercial aspect is important both in length of the stems, as the button, being one of the big worries, especially in months of withering, therefore, the company “Trébol Roses”, considered evaluating the effect of the application of bioregulators on vegetative and productive phenology at different concentrations in the Freedom, Mondial and Vendela varieties, with the aim of stepping up production and the export quality. The results vary as to variables and varieties, for the vegetative phase varieties Freedom and Mondial the best concentration was 0.5 cc/l while for Vendela 1 cc/l was lt. On the other hand, for the productive phase the concentration that showed the best results was 1.5 cc/l for Freedom, 1 cc/l for Vendela and for Mondial between the concentration 1 cc/l and 1.5 cc/l. The application of bioregulators at different concentrations directly influenced the phenological states of the rose, both vegetative and productive, and the yield of the Freedom, Vendela and Mondial varieties.
