Phenological characteristics of early strawberry cultivars in the open field and under a high plastic tunnel

Abstract

The objective of this study was to analyze phenological traits of newly cultivars of strawberry from early ripening group: Clery, Queen Elisa and Madeleine. Plants were grown on black mulch foil, at the distance 30x30 cm, with fertirigation. The planting was done at the end of July 2004. in the Institute PKB Agreokonomik. During the period of 2005-2007 flowering and ripening time was observed the open field and under a high plastic tunnel. The earliest flowering and ripening time had cultivar Clery. Compare to open field, in the plastic tunnel start of flowering was 11 and ripening 10 days early for all cultivars.

Cilj rada je ispitivanje fenoloških osobina novijih sorti jagode ranijeg vremena zrenja: Clery, Queen Elisa i Madeleine. Jagode su gajene na crnoj foliji, sa razmakom sadnje 30x30 cm, uz obezbeđenu fertirigaciju. Sadnja je obavljena krajem jula 2004. god. na Oglednom polju Instituta PKB Agroekonomik. U periodu 2005-2007. praćeno je vreme cvetanje i sazrevanja kod biljaka gajenih na otvorenom polju i u plasteniku. Najranije vreme cvetanja i sazrevanja imala je sorta Clery. Sve ispitivane sorte počinju da cvetaju i sazrevaju prosečno 11, odnosno 10 dana ranije u plasteniku nego na otvorenom polju.
