ABSTRACT
A field experiment was conducted in 2013-2014. The experiment had a randomised block design with three replicates. The first experimental factor was two carrot (Daucus carota L.) cultivars, ‘Purple Haze F1’ and ‘Deep Purple F1’, and the second experimental factor was the application of the biocontrol agent Bioczos BR. In the control treatment, plots were sprayed with water. The aim of the study was to determine the effect of Bioczos BR on selected morphological traits and the nutritional value of purple-coloured storage roots of carrots. The analysed carrot cultivars differed considerably in root weight and length. Carrots of cv. ‘Deep Purple F1’ had higher average root weight. Consistent changes were observed in the nutrient content of carrot roots. Bioczos BR contributed to an increase in the content of dry matter (by 14%), total sugars (by 28%), reducing sugars (by 31%) and nitrates (V) (by 32%) in carrot roots, in comparison with the control treatment.

Doświadczenie polowe przeprowadzono w latach 2013-2014. Eksperymentu dokonano metodą losowych podbloków w trzech powtórzeniach. Pierwszy czynnik doświadczalny stanowiły rośliny dwóch odmian marchwi (Daucus carota L.), „Purple Haze F1” i „Deep Purple F1”, a drugim eksperymentalnym czynnikiem było zastosowanie środka Bioczos BR do biologicznej ochrony. Obiekt kontrolny spryskiwano wodą. Celem badania było określenie wpływu preparatu Bioczos BR na wybrane cechy morfologiczne i wartość odżywczą purpurowych korzeni spichrzowych marchwi. Analizowane odmiany marchwi różniły się znacznie pod względem masy i długości korzeni. Rośliny marchwi odmiany „Deep Purple F1” miały wyższą średnią masę korzeni. Zaobserwowano stałe zmiany w zawartości składników odżywczych korzeni marchwi. Bioczos BR przyczynił się do wzrostu suchej masy (o 14%), całkowitej zawartości cukrów (o 28%), cukrów redukujących (o 31%) i azotanów (V) (o 32%) w korzeniach marchwi, w porównaniu do obiektu kontrolnego.
