AB  - Cilj rada je bio evaluacija uticaja posležetvene, veštačke inokulacije fitopatogenom gljivom Monilinia laxa na sadržaj šećera i organskih kiselina u plodovima devet sorti trešnje (Prunus avium).
AB  - The aim of the study was to evaluate impact of postharvest, artificial inoculation with Monilinia laxa pathogenic fungus on sugars and organic acids contents in fruits of nine sweet cherry (Prunus avium) cultivars: ‘Burlat’, ‘Priusadebnaja’, ‘Asenova rana’, ‘Lionska’, ‘Sue’, ‘Junska rana’, ‘Merchant’, ‘Summit’ and ‘3/VAL'. M. laxa represents one of the major pre- and postharvest pathogens of fresh fruits, causing significant economic losses. Due to different possibility of disease incidence in tested cultivars, artificial inoculation would explain how this pathogen affects quality of tested fruits. Determination of individual sugars and organic acids was performed by HPLC methods. For sugars, mobile phase was twice distilled water (0.6 mL/min); Rezex RCMmonosaccharide Ca+ (2%) column (300mmx7.8 mm, Phenomenex) operated at 65 °C, 30 min the total run time. Organic acids were analyzed as follows: 4 mM sulphuric acid in twice distilled water 30 min, Rezex ROA-organic acid H+ (8%) column operated at 65 °C, UV detector 210 nm. Contents of sugars in this study were (in g/kg dry weight): glucose 205-439 and 268-443, fructose 175-398.9 and 208.6-365.8 and sucrose 20-47.6 and 19.2-38.6, in healthy and infected fruits, respectively. Organic acids detected in sweet cherry cultivars were citric, malic, quinic, shikimic and fumaric acid, and their content varied depending on cultivar and treatment. Only ‘Burlat’ accumulated tartaric acid after the infection. ‘Junska rana’ and ‘Merchant’ had significantly decreased organic acids content after the infection, while ‘Sue’ and 3/VAL reacted to the infection by accumulation, especially of fumaric acid.

AB  - Compounds which add to bioactivity of elderberry (Sambucus nigra L.) are mostly phenolic compounds. One wild edible and two cultivated genotypes (’Haschberg’ and ’Ljubostinja’ selections) have been chosen. Leaves and fruits were collected in four stages (April-September). Total phenolics (TP) content was determined from MeOH extracts by Folin-Ciocalteau method while determination of individual compounds was performed using HPLC-DAD-ESI-MSn analysis with a DAD at 280, 350 and 530 nm. TP content in leaves varied through developmental stages, being higher in II and III stage. Leaves and fruits (both unripe and ripe) of ’Ljubostinja’ plants had higher content of TP compared to wild ripe fruits (1.5-fold). Leaves had caffeic acid derivatives (0.3-0.7% in wild, 0.2-0.3% in ’Haschberg’ and 0.4-0.6% in ’Ljubostinja’ in dry weigh) and caffeoylquinic acid derivatives, while fruits had more caffeoylquinic acid derivatives, particularly unripe fruits. The major phenolic acid present in leaves, especially during the II stage of development, was chlorogenic acid (approx. 4% dw) and the same was recorded in fruits (0.03% dw in unripe fruits of wild plants). Content of phenolic acids decreased during ripening of elderberry fruits and the similar was detected in the leaves.
