Abstract

STRASSBURGER, André Samuel et al. Strawberry growth: effect of cultivar and plant position in the bed. Cienc. Rural [online]. 2011, vol.41, n.2, pp.223-226. ISSN 0103-8478.  http://dx.doi.org/10.1590/S0103-84782011000200006.

The aim of this research was to evaluate the growth of strawberry cultivars growing in organic crop system observing the influence of plant position in the bed on accumulated dry matter production and its partitioning among the aboveground plant organs. The experiment was conducted in Embrapa Clima Temperado, Estação Experimental Cascata, Pelotas, RS. The treatments were compose by the combination of two experimental factors: cultivar ('Aromas', 'Albion', 'Camarosa' and 'Camino Real') and plant position in the bed (Central and Border). The experimental design used was randomized blocks with split-plots and four replications. 'Camarosa' cultivar presented highest dry mass production of aboveground organs (62.3; 27.5 and 88.0g plant-1 for leaves, crown and fruits, respectively), and together 'Aromas', highest yield (64.2 and 59.1Mg ha-1, respectively). 'Aromas' cultivar presented highest fruit dry mass contribution for the total aboveground dry mass production (60.6%) and the highest harvest index (88%). The plant position in the bed did not influence the growth and yield of the plants, which indicate no border effect for the 'Albion', 'Aromas', 'Camarosa' and 'Camino Real' strawberry cultivars.

Keywords : Fragaria x ananassa Duch.; organic crop system; dry mass production and partitioning; border effect.
