20.500.12556/DKUM-92044 Kemijska sestava in morfološki deskriptorji plodov akcesij Prunus domestica L. in P. cerasifera Ehrh. magistrsko delo Chemical composition and morphological descriptors of the fruits of the accessions of Prunus domestica L. and P. cerasifera Ehrh. Magistrska naloga obravnava kemijsko sestavo in morfološke deskriptorje plodov akcesij dveh vrst sliv: Prunus domestica L. in P. cerasifera Ehrh. Namen raziskave je bil ugotoviti razlike v kemijskih in morfoloških lastnostih plodov med tema dvema vrstama ter oceniti njihov potencial kot vir antioksidantov in sladkorjev. V raziskavo smo vključili 31 akcesij sliv, ki smo jih analizirali glede na 18 morfoloških deskriptorjev ter vsebnost sladkorjev, skupnih fenolov in antocianinov. Statistično značilne razlike smo ugotovili pri naslednjih morfoloških lastnostih: velikost plodov, lateralna oblika plodu, simetrija plodu v vertikalnem pogledu, globina šiva sadja pri peclju, barva mesa, trdnost mesa, sočnost ploda ter stopnja spojenosti koščice in mezokarpa. Na drugi strani statistično značilne razlike niso bile ugotovljene pri depresiji na vrhu ploda, prisotnosti dlakavosti, globini votline peclja ploda, osnovni barvi kože, obliki koščice v lateralnem in ventralnem pogledu, površini endokarpa, širini dna koščice ter obliki vrha koščice. Rezultati so pokazali, da se akcesije razlikujejo po barvi eksokarpa. Najpogostejša barva plodov je bila rdeča, ki je predstavljala 36 % vseh plodov, sledi rumena z 21 % in škrlatno vijolična z 12 %. Analiza je pokazala, da je barva plodov v pozitivni korelaciji z vsebnostjo antocianinov. Plodovi z rdečo barvo kože so imeli visoke vrednosti antocianinov (mediana 180,50 mg/100g) in nizke vrednosti sladkorjev (mediana 14,70 °Brix). Plodovi z zeleno barvo eksokarpa so imeli visoke vrednosti sladkorjev (mediana 19,40 °Brix) in nizke vrednosti antocianinov (mediana 7,60 mg/100g). Spearmanov korelacijski test je pokazal, da obstaja močna pozitivna korelacija med vsebnostjo skupnih antocianinov in fenolov. The master's thesis examines the chemical composition and morphological descriptors of the fruits of accessions from two plum species: Prunus domestica L. and P. cerasifera Ehrh. The aim of the study was to determine the differences in the chemical and morphological properties of the fruits between these two species and to assess their potential as a source of antioxidants and sugars. The study included 31 plum accessions, which were analyzed based on 18 morphological descriptors and the content of sugars, total phenols, and anthocyanins. Statistically significant differences were found in the following morphological traits: fruit size, lateral shape of the fruit, fruit symmetry in vertical view, depth of the suture at the pedicel, flesh color, flesh firmness, fruit juiciness, and the degree of adhesion between the stone and mesocarp. On the other hand, no statistically significant differences were found in the presence of depression at the fruit apex, presence of pubescence, depth of the pedicel cavity, basic skin color, stone shape in lateral and ventral views, endocarp surface, stone base width, and stone apex shape. The results showed that the accessions differ in exocarp color. The most common fruit color was red, representing 36 % of all fruits, followed by yellow with 21 % and scarlet-purple with 12 %. The analysis revealed that fruit color is positively correlated with anthocyanin content. Fruits with red skin had high anthocyanin values (median 180.50 mg/100g) and low sugar values (median 14.70 °Brix). Fruits with green exocarp color had high sugar values (median 19.40 °Brix) and low anthocyanin values (median 7.60 mg/100g). Spearman's correlation test indicated a strong positive correlation between total anthocyanin and phenol content. fenoli antocianini mirabolana sliva ringlo phenols anthocyanins Mirabelle plum greengage true true false K.
