    Abstract: Garden rose, Rosa hybrida, is primarily used for decoration and has a wide range of growing area, contrary to R. damascena that has a limited area of distribution (Turkey and Bulgaria), yet it is extensively used for commercial production of valuable and expensive rose oil. Since the content of essential oil in rose petals is low (0.03–0.04%), its production is quite limited; however, during this process, a significant amount of rose hydrosol is obtained as a secondary product. The aim of this research was to determine the chemical composition of garden rose hydrosols and to evaluate their biological properties. Obtained results show that R. hybrida hydrosol containing phenylethyl alcohol, nerol, linalool, and geraniol may be used as an alternative for R. damascena hydrosol. However, the total phenolic content was quite low (4.96 µg GAE/mL), which is related to a low level of observed antioxidant activity based on different antioxidant activity assays. Furthermore, R. hybrida hydrosol did not exhibit antimicrobial activity against several gram-positive and gram-negative bacteria, as well as yeast and fungi. Anti-inflammatory activity was also low, while no antihyperglycemic activity was detected. With these results in mind, no potential is evident for the therapeutic application of rose hydrosol beyond that found in complimentary medicine such as aromatherapy.

    Abstract: The aim of this study was to test the quality (physicochemical and sensory odor properties) and bioactivity (antimicrobial and antioxidant activities) of the essential oils (EO) obtained from the most frequently cultivated lavender and lavandin varieties in Serbia, whose cultivation areas were previously reserved for warmer climates, outside the agroecological region of Serbia. Seven EO from true lavenders (L. angustifolia Mill. and cultivars: ‘Hidcote blue’, ‘Munstead’, ‘Primorska’), Croatian indigenous lavandin cultivar (L. × intermedia ‘Budrovka’), lavandin ‘Grosso’ and one undetermined lavender sample (Lavandula sp.) showed compliance with standard requirements for lavender EO composition (contents of linalool 23.9–30.2% and 28.9–36.9%, and of linalyl acetate 22.2–32.2% and 6.9–20.7% in true lavender and lavandin samples, respectively). All EO were characterized as pleasant, with a floral aroma as a prominent odor. Samples exhibited high antimicrobial activities (3.5–14.2 µL mL−1 MIC and MBC values) against important Gram-positive (B. cereus and L. monocytogenes) and Gram-negative bacteria (E. coli) and yeasts (C. albicans), and high antioxidant capacity (IC50 values of 0.23–0.59 µg AAE mL−1 EO). This preliminary research on the quality of lavender EOs reveals the potential of this species for the future of medicinal and aromatic plant species production and further diversification of agriculture in the area.

    Abstract: Sorghum grain (Sorghum bicolor L. Moench) is a gluten-free cereal with excellent nutritional value and is a good source of antioxidants, including polyphenols, as well as minerals with proven health benefits. Herein, the phenolic composition, elemental profile, and antioxidant activity of sixteen food-grade sorghum grains (S1–S16) grown under agroecological conditions in Serbia were determined. Nine phenolic compounds characteristic of sorghum grains, such as luteolinidin, 5-methoxyluteolinidin, luteolidin derivative, luteolidin glucoside, apigeninidin, 7-methoxyapigeninidin, apigeninidin glucoside, and cyanidin derivative, were quantified. The antioxidant potential of the analyzed sorghum grains was evaluated by UV/Vis (DPPH, ABTS, and FRAP) and Electron Paramagnetic Resonance spectroscopy (hydroxyl and ascorbyl radical scavenging assays). The content of macro- and microelements was determined by Inductively Coupled Plasma Optical Emission spectroscopy. Theoretical daily intakes of selected major and trace elements were assessed and compared with the Recommended Daily Allowance or Adequate Intake. Sample S8 had the highest amount of phenolic compounds, while S4, S6, and S8 exhibited the strongest antioxidative potential. The sorghum studied could completely satisfy the daily needs of macro- (K, Mg, and P) and microelements (Se, Zn, Fe). Pattern recognition techniques confirmed the discrimination of samples based on phenolic profile and elemental analysis and recognized the main markers responsible for differences between the investigated samples. The reaction between hydroxyl radicals and luteolinidin/apigeninidin was investigated by Density Functional Theory and thermodynamically preferred mechanism was determined.

    Abstract: Ecological conditions of the growing areas, growing practices as well as harvest and postharvest processing influence the yield and quality of chamomile. The aim of this research was to determine the influence of chamomile separation methods, as postharvest treatments, on the essential oil quality and content, with a view to improve current primary processing of this valuable medicinal plant. In order to explain the structure of laboratory data that would give deeper assessment of similarities among various samples of chamomile essential oil, PCA was employed. Tested results showed that separation of chamomile plant material, as postharvest and pre-drying treatment, had significant influence on the number of identified compounds in the chamomile essential oil. The highest content of individual essential oil compounds had chamomile flowers with short stems, especially a-bisabolol, chamazulene, Z-spiroether and E-b-famesene. In the essential oil obtained from chamomile flowers with long stems, content of a-bisabolol and chamazulene were significantly lower, while E-b-famesene and Z-spiroether contents were significantly higher. Furthermore, in the essential oil obtained from chamomile plant material without separation, the lowest content of abisabolol and Z-spiroether, and the highest content of E-b-farnesene were recorded. The correlation analysis was performed to investigate the likeness in the amounts of the active compounds of essential oil from differently processed chamomile samples. All these results indicate the importance of precise and controlled postharvest treatments, since it clearly affects the essential oil quality and content in the primary processing of this valuable medicinal plant.

    Abstract: Prema klimatskim scenarijima RCP-a, hrast lužnjak ( Q. robur L.) označen je kao najteže pogođena vrsta drveća zbog stalnih, intenzivnih klimatskih promjena. Propadanje hrastovih šuma može uzrokovati velike ekonomske gubitke, budući da se hrastovi smatraju vrlo vrijednim primjercima drveća zbog duge povijesti iskorištavanja za proizvodnju drva i gradnju (Mikac i sur., 2018.). Uzimajući u obzir da uobičajeni biokemijski parametri mogu doprinijeti razumijevanju temeljnih obrambenih mehanizama biljaka protiv stresa od suše i stoga se koristiti kao pouzdani deskriptori prilagodljivosti u kontekstu klimatskih promjena, cilj ove studije bio je utvrditi postoji li neki od 7 predloženih testova praćenja oksidacijskog stresa (ukupni sadržaji bjelančevina, fenola, flavonoida i testovi hvatači slobodnih radikala – ABTS, NO, FRAP i DPPH) koji može poslužiti za dugoročni genetski monitoring dviju sorti hrasta lužnjaka (rani vs kasni). Fenološki varijeteti [rani (var. praecox ) vs kasni (var. tardissima )] i fiziološka skupina (vitalne ili oštećene) bile su promatrane varijable u testiranih jedinki zbirnog radnog hrasta vitalnog (PEOV), zbirnog ranog hrasta oštećenog (PEOD), zbirnog kasnog vitalnog (PLOV) i zbirnog ranog oštećenog (PLOD). Svaka objedinjena (zbirna) skupina sadržavala je ukupno 10 ili 11 uzoraka, mjerenih u tri primjerka kako bi se postigla optimalna statistička značajnost za svaku skupinu (za više, pogledajte pododjeljak Statistika). Sakupljeno lišće odmah je označeno i stavljeno u aluminijski folij, konzervirano na suhom ledu i transportirano u Laboratorij za kemijske i biokemijske analize Instituta za nizinsko šumarstvo i okoliš (ILFE) na daljnju obradu. Dva grama hrastovog lišća homogenizirano je u ohlađenom mužaru s tučkom s 10 ml fosfatnog pufera (0,1 M KH2PO4, pH=7), centrifugirano 10 min na 11000 okretaja u minuti i supernatant je korišten za daljnji test praćenja oksidativnog stresa (Tablica 1), prema uputama autora. Sve analize određene su spektrofotometrijski u mikropločicama s čitačem Multiplate MultiScan GO (Thermo Scientific, Njemačka). Dobiveni rezultati biokemijskih parame tara pokazali su da je lišće kasnog hrasta imalo veći sadržaj bjelančevina i fenolnih spojeva od ranog, bez obzira na fiziološku skupinu (vitalno ili oštećeno) (Tablica 2). Štoviše, radi boljeg prikaza rezultata iz Tablice 2. prikazali smo ih grafički (Graf 1. i 2.). Najveći udio ukupnih flavonoida imali su listovi PLOD i PLOV, a najmanji listovi PEOV i PEOD (Tablica 2). Što se tiče ispitivanja kapaciteta hvatanja radikala, svi testirani listovi imali su nizak kapacitet hvatanja. ABTS- i NO- testovi hvatači radikala pokazali su manje od 50% hvatanja za sve uzorke, dok je DPPH-test pokazao neznatno više od 50% hvatanja za PEOD, PEOV, PLOV listove (56,15%, 57,28% odnosno 51,58%) i 41,69 % za listove PLOD. Kasno lišće hrasta ima veću antioksidacijsku moć reduciranja željeza (203,5 odnosno 180,4 mg TE/g FW) nego rano (93,9 odnosno 85,5 mg TE/g FW), bez obzira na fiziološku skupinu (Tablica 2). Razlike između ranih i kasnih genotipova hrasta bile su značajnije u pogledu ukupnog sadržaja fenola i flavonoida, kao i antioksidativne moći reduciranja željeza (FRAP). Ovo zapažanje također je potvrđeno PCA analizom, gdje su sva tri parametra grupirana zajedno s malom razlikom u najdominantnijoj komponenti PC1 (Graf 3). Dvosmjerna ANOVA u našem slučaju pokazala je da fiziološko grupiranje nije imalo utjecaja na ukupni sadržaj fenola i naknadno na aktivnost hvatača radikala FRAP, ABTS i NO. Dobiveni rezultati mogu pomoći da se objasne razlike u biokemijskim odgovorima na abiotičke stresove stabala hrasta lužnjaka na različitim mikrolokalitetima i na razini varijeteta unutar jednog šumskog kompleksa te nam mogu pružiti vrijedne informacije o varijabilnosti unutar vrste u otpornosti na sušu (rano naspram kasno). Stoga ovo može biti važan alat za poboljšanje strategija uzgoja i planova umjetne regeneracije hrasta lužnjaka u sušnijim nizinskim regijama. S obzirom na rezultate, potrebno je dugoročno mjerenje parametara oksidacijskog stresa stabala hrasta na individualnoj i populacijskoj razini, kako bi se dobila jasnija slika o tome kakve se promjene događaju na molekularnoj razini. Ova mjerenja također mogu biti korisna u genetskom praćenju stabala hrasta postavljenih u polukontroliranim i kontroliranim uvjetima. Na taj način bi se mogao dobiti uvid u točan genetski kapacitet vrsta drveća u pogledu njihove otpornosti na abiotski stres na pojedinim mikrolokalitetima unutar krajolika.

    Abstract: Monilinia laxa Aderh. and Ruhl. is the predominant causal agent of brown rot disease of stone fruit orchards, especially sweet cherries. The objective of this study was to identify reaction in response of nine genotypes cherry, with different pomological properties, against brown rot. These genotypes were harvested at commercial maturity from orchard in the Fruit Research Institute in Rimski Šančevi. The studied genotypes showed significant differences in terms of the occurrence of disease on fruits, both under artificial inoculation and infection in the field. Given the fact that sweet cherry fruits are prone to infection by a number of pathogens in the field, biochemical parameters were analysed on artificially inoculated fruits. Biochemical analysis of fruits determined significant differences in contents of total phenols, flavonoids and anthocyanins, as well as in antioxidant activity. It was genotype specificities and intensity of infection, as well as the interaction of the two that induced differences in the secondary biomolecules content and antioxidant activity. The majority of the genotypes examined showed high polyphenolics content, while under the infection, the content was significantly lower. Based on the results obtained, the secondary metabolites content can be used as one of the parameters for evaluating the resistance of sweet cherry genotypes to brown rot.

    Abstract: Crop cultivation under the open-field conditions depends on a variety of biotic and abiotic factors which cause plant stress and deterioration. Due to high soil salinity, some soils can be an unfavourable growing environment for most plants. As a low productivity soil type, solonetz soils are a stressful growing environment, causing plant deterioration. Plants have developed a complex antioxidative defense system as a precaution against oxidative stress caused by high soil salinity. The trial was set up on a halomorphic soil type-solonetz. The research included ten cultivars, one local population of hexaploid wheat (Triticum aestivum ssp. aestivum L.) and one cultivar of triticale (Triticosecale W.). The activity of enzymatic and non-enzymatic antioxidants in plant antioxidative defense system was detected during the trial, as well as lipid peroxidation. The analysis of biochemical markers was done in the flowering stage, and then in the milk maturity phase. Research results of the tested components revealed the highest stress tolerance exhibited by genotypes Banatka and Bankut 1205. Understanding the process of oxygen radical production by the plant tissue contributes to breeding wheat cultivars for better stress tolerance. Selection of genotypes better adapted to growing conditions in solonetz soils could facilitate a more economically justifiable wheat production, and promote utilization of the lower-quality soil types in agriculture.
