CALVETE, Eunice Oliveira et al. Phenology, production and content of strawberry crops cultivars anthocyanins produced under protected environment. Rev. Bras. Frutic. [online]. 2008, vol.30, n.2, pp.396-401. ISSN 1806-9967. http://dx.doi.org/10.1590/S0100-29452008000200022.
The diversification of strawberry cultivars demands studies about their adaptation in the cultivation place and, the increase of the consumer's requirement for healthier products require studies about the products nutraceutica characteristics. In such a way, this work aimed to determine the cultivars with higher adaptation under protected environment in Rio Grande do Sul, Planalto Médio region, the contents of anthocyanins, as well as the period that provides more productivity. The experiment was conduced in an inside structure of 280 m2 covered with PEBD film, with 150 µm and anti UV additive. The designs were arranged in split plots with 3 repetitions, the treatments in subdivided portions, and the period for planting seedlings (April 28th and May 13th) the main plots, and the cultivars (Dover, Tudla, Comander, Oso Grande, Campinas, Chandler, Serrano e Camarosa), the sub-plots. Phenological characteristics and yield components were evaluated. The content of anthocyanins was determinated by using a specterphotometer with wave length of 528 nm. There was no interaction between cultivars and planting periods about the evaluated characteristics. The higher productivity was the earlier planting strawberry crop in April. The cultivars Camarosa, Dover, Oso Grande and Tudla are the most recommended for their greater productivities and range of production periods, and "Serrano" cultivar for higher antocianin levels.
