The Influence of Production Systems on Sensory Characteristics of Lettuce (Lactuca sativa L.)

V diplomskem delu smo preučevali senzorične lastnosti dveh sort solate (\u27Comice\u27 in \u27Leda\u27) iz različnih pridelovalnih sistemov (konvencionalni, integrirani, ekološki in biodinamični) na podlagi hedonskega preizkusa. Solata je bila pridelana v letu 2015 v dolgoletnem poljskem poskusu na Univerzitetnem kmetijskem centru Pohorski dvor (UKC). preizkuševalci so na 10 cm dolgi daljici z označenima koncema (z obrazi od »zelo mi ne ugaja« do »zelo mi ugaja«) ocenjevali barvo, obliko listov, hrustljavost, okus, sočnost in skupni vtis vzorcev solate. Rezultati so pokazali, da ima preizkuševalec statistično značilen vpliv na ocenjevane parametre, da pridelovalni sistemi ne vplivajo na ocenjevane parametre in da sorta statistično vpliva na barvo, obliko in skupni vtis. Sorta \u27Comice\u27 ima pri ocenjevanih parametrih, kot so barva, oblika in skupni vtis značilno boljše ocene v primerjavi s sorto \u27Leda\u27.In this diploma thesis, we studied the sensory properties of two varieties of lettuces (\u27Comice\u27 and \u27Leda\u27) from the different production systems (conventional, integrated, organic and biodynamic) on the hedonic test. The lettuces was produced in 2015 in a longt ime field experiment at the University Agriculture Centre Pohorje (UKC). Examiners evaluated the lettuces with the help of a 10 cm line segment which was marked at both ends (from not very pleasing to pleasing), and they were evaluating colour, shape of leaves, crunchiness, taste, juiciness and the overall impression of the lettuces samples . The results showed that the tester has a statistically significant effect on the assessment parameters that cultivation systems do not have an impact on the evaluated parameters, and that the variety of the lettuces statistically affects the colour, shape, and overall impression. The variety \u27Comice\u27 had significantly better ratings in the evaluated parameters of colour, shape and overall impression when compared to the \u27Leda\u27
