The influence of integral and organic growing systems on sugar content in selected tomato types and cultivars

Interest in production of protected crops has grown significantly over the past decade. Different cultivation systems (conventional, integral, and organic) affect the biological activity, which is ultimately reflected in the high quality of the fruits of different vegetable crops. In accordance with the requirements for health-safe products without residues of harmful substances in fruits, there is an increasing need for the production of tomatoes in integral and organic production systems. One of the most important features of these vegetables is their high quality and health safety, high nutritional and biological value. Agricultural production systems and growing practices are critical factors in determining the nutritional quality of tomato fruits [1]. In tomato, the sugar content is one of the important factors and one of the most significant parameters from the aspect of food quality [1]. Therefore, the aim of this work is to monitor fluctuations in sugars content, as parameters that determine the nutritional value in tomato cultivars, induced by growing under integral and organic conditions. For this purpose, a set of sixteen samples of four types of tomatoes - beef, grapolo, mini and midi plum, and cherry - was analyzed. Each type of tomato included two varieties, grown in two agricultural systems - integral and organic. The sugars profile was obtained using High-Performance Anion Exchange Chromatography with Pulsed Amperometric Detection (HPAECPAD). The content of eleven sugar components was determined. Fructose and glucose were the major sugar compounds [2], while the sugar microcomponents were trehalose, arabinose, melibiose, sucrose, isomaltose, gentiobiose, raffinose, maltose, and panose. The results showed differences between samples produced in integral and organic growing systems, primarily in microsugar components. Higher content of trehalose and melibiose was found in samples obtained from organic production. Fig.1.

Morphological and biochemical variability in different populations of wild sweet cherry (Prunus avium L.)

Three autochthonous populations of wild sweet cherry (P. avium L.) have been collected from Southwest Serbia. Biochemical and morphological variability in these populations were analyzed. Observed zymograms for five enzyme systems did not show patterns different from sweet cherry cultivars already analyzed. The discrimination effect of eight characters was examined with multivariate analysis. The results of classification obtained according to the linear discriminant functions express a very slight difference between the real and evaluated groups. For effective discrimination, these eight characters can be reduced to only five with more than 90% reliability. These five characters are: fruit maturity, juice colour, tree habit, yield and seed germination

Genetic resources of cherry plum (Prunus cerasifera ehrh.)

Investigations were carried out on 63 cherry plum genotypes collected from different autochthonous populations in Serbia. Morphological and biochemical variability of these genotypes was analyzed by multivariate analysis (cluster analysis and discriminant linear analysis). Cluster analysis showed clear differences between cherry plum genotypes and four distinct clusters were identified. Discriminant linear analysis used ripening time to create timed preliminary groups. Most genotypes of the first (82%) and the third (71%) group from the results of discriminant analysis were correctly classified but fewer of the second group (45%). Four fruit characters, ripening time, length, stone weight and total acid content, are sufficient to explain the diversity between the starting groups and to provide a good classification. Multivariate analysis is a useful system for germplasm evaluation in cherry plum allowing a detail characterization of seedlings in terms of adaptation and productivity. The presence of diversity within the germplasm collection is of great interest in providing valuable materials for breeding aimed at cherry plum improvement for different environments

Chemical Composition of Two Different Extracts of Berries Harvested in Serbia

Total phenolic content (TPC), total anthocyanin content (TAC), free and total ellagic acid content, sugars, minerals, and radical scavenging activity were determined in nine berries harvested in Serbia. More than 30 phenolic compounds. were identified; among them, 11 polyphenols and cis,trans-abscisic acid were quantified using UHPLC coupled with an LTQ: Orbitrap XL mass analyzer. For the first time chrysin, naringenin, pinocembrin, and galangin were quantified in some of the investigated berry species. The extraction efficiency of the two extraction systems, methanol and acetone, was investigated. It was found that acetone is a better extracting solvent for TPC, whereas more TAC was extracted by methanol. TPC in acetone extracts ranged from 177.51 to 459.71 mg gallic acid equiv/100 g frozen weight. TAC ranged from 5.39 to 96.94 mg cyanidin-3-glucoside/100 g frozen weight in methanol extracts. The amounts of both free and total ellagic acid were found to be higher in the acetone extract in comparison to the methanol extract

The polyphenolics and carbohydrates as indicators of botanical and geographical origin of Serbian autochthonous clones of red spice paprika

Spice peppers (Capsicum annuum L.) var. Lemeska and Lakosnicka paprika were investigated to evaluate their polyphenolic and carbohydrate profiles and antioxidant activity. A total of forty-nine polyphenolics were identified using ultrahigh-performance liquid chromatography (UHPLC) coupled to LTQ OrbiTrap mass analyzer. Twenty-five of them were quantified using available standards, while the other compounds were confirmed by exact mass search of their deprotonated molecule [M-H](-) and its MS4 fragmentation. Thirteen carbohydrates were quantified using high-performance anion exchange chromatography (HPAEC) with pulsed amperometric detection (PAD). Radical scavenging activity (RSA) ranged from 17.32 to 48.34 mmol TE (Trolox equivalent)/kg DW (dry weight) and total phenolics content (TPC) was ranged between 7.03 and 14.92 g GAE (gallic acid equivalents)/kg DW. To our best knowledge, five polyphenolic compounds were for the first time tentatively identified in paprika: 5-O-p-coumaroylquinic acid, luteolin 7-O-(2 ''-O-pentosyl-4 ''-O-hexosyl)hexoside, quercetin 3-O-(2 ''-O-hexosyl)rhamnoside, isorhamnetin 3-O-[6 ''-O-(5-hydroxyferuloyl)hexoside]-7-O-rhamnoside, and luteolin 7-O-[2 ''-O-(5'''-O-sinapoyl)pentosyl-6 ''-O-malonyl]hexoside.
