Yield and quality of fruit of introduced strawberry cultivars
Rodnost i kvalitet ploda introdukovanih sorti jagode
Abstract
During 2004-2005, studies were conducted at the Experimental farm 'Radmilovac', a collective strawberry plantation of the Faculty of Agriculture, Belgrade. The experiment included seven strawberry cultivars six introduced cvs (Evita, Madeleine, Eris, Selena, Cortina and Favette) and a standard domestic cultivar Čačanska Rana. All cultivars were grown on banks covered with black polyethylene foil, in the form of two-row bands. Cropping (per plant and ha) as well as major parameters of fruit quality (fruit mass fruit dimension, fruit shape index, soluble solids content, sugar content total acids content, ascorbic acid content and pH value of fruit) were studied. The ripening period of all the studied cultivars was an early one and it ranged from 21th to 28th May. The highest yield (33.0-37.7 t/ha) and the best fruit quality (the largest fruit and high content of all chemical compounds) were recorded in cvs Cortina, Madeleine and Eris. These cultivars can be recommended for commercial gro...wing in the region of Smederevsko Podunavlje.
Kod šest introdukovanih sorti jagode (Evita, Madeleine, Eris, Selena, Cortina i Favette) i kao standard sorte Čačanska rana, ispitivana je rodnost i kvalitet ploda. Ispitivanja su vršena u kolekcionom zasadu jagode Poljoprivrednog fakulteta iz Beograda, na OD 'Radmilovac', u periodu 2004-2005. godine. Sve sorte su gajene na bankovima prekrivenim crnom polietilenskom folijom, na rastojanju sadnje 40 x 30 cm. Proučavana je rodnost, izražena po bokoru i jedinici površine, kao i važniji pokazatelji kvaliteta ploda (masa, dimenzije, index oblika, sadržaj rastvorljive suve materije, šećera, kiselina, vitamina C i pH vrednost). Sve ispitivane sorte su sazrevale vrlo rano, u rasponu od 21. do 28. maja. Najbolju rodnost (od 33,0 do 37,7 t/ha) i kvalitet ploda (najveća masa i visok sadržaj svih hemijskih komponenata) ispoljile su sorte: Cortina, Madeleine i Eris. Ove sorte se mogu preporučiti i za komercijalno gajenje u uslovima smederevskog Podunavlja.
