The lecture was held at 14. Serbian Congress of Fruit and Grapevine Producers with international participation. The lecture represented an introduction to the Physiology and ecology of fruits and grapevine section. Plant primary and secondary metabolites determine fruit inner and outer quality parameters. Different factors influence the content of selected sugars, organic acids and phenolics in different plant species. The content of metabolites can vary among plant species and cultivars. Differences can appear between different organs or even tissue. Outer tissue of fruits or seeds of different cultivars contain much higher amounts of phenolics compared to inner fruit parts. Cultural practices as well as ecological parameters can be an important trigger for different synthetic pathways. Especially the biosynthesis of secondary compounds is affected by stress stimulations like wounding or pathogen attack. Therefore, there is a growing interest in analytical data on fruit chemical composition due to health promoting properties as well as commercial benefits.

COBISS.SI-ID: 72825533rd Slovenian Fruit Growing Congress with International Participation was held in Krško from 21. – 23. 11. 2012 and was organized by Chair of Fruit Growing, Viticulture and Vegetable Growing, Department of Agronomy, Biotechnical faculty and Slovenian professional fruit society. 131 participants from Slovenia and other countries attended and 63 studies were presented – in oral and poster form. Proceednigs consists of 446 pages and was given to all the congress participants. The congress covered research on production technologies, fruit storage and marketing.

COBISS.SI-ID: 263935488A chapter in book on berries informs on elderberry botany, production, technology and chemical composition of flowers, berries and elder products. The uses of American and European Elderberry are presented to broader scientific and general public. The antioxidant, antimicrobial, anti-inflammatory and cancer-chemo preventive properties of elderberry products are reported and readers are informed on chemical composition of elderberry. Specifically, primary metabolites (organic acids, sugars), secondary metabolites (phenols) and several other constituents (vitamins A and C, cytokines) are reported. The comparison of different elder species, plant organs and products reveals great differences among them. Elder flowers exhibit a much stronger neutralizing activity of free radicals compared to elderberry fruit. The knowledge on natural antioxidants, anthocyanins and vitamins abundant in elderberry flowers and fruit are concisely presented and inform the broader public on beneficial effects of elderberry products. Elderberry products can represent an interesting addition to touristic offer on farms and promote organic production of less known fruit species in Slovenia.
F.02 Acquisition of new scientific knowledge
COBISS.SI-ID: 7099001From 25. – 26. January 2012, 4th Slovenian Congress on Vitiviniculture was organized in Nova Gorica in cooperation with Biotechnical Faculty, University of Ljubljana, AFI NG and SDVVS. The event was attended by 250 participants, including 30 foreign viticulture and enology experts. Lectures were held in Slovenian and English language, and simultaneous translation into both languages was organized. A total of 27 papers were presented and 11 invited speakers from abroad presented their work. The congress was organized in four sessions: viticulture, winemaking, economics and eco-tourism. Proceedings were published and are available on the website www.svvk.si in addition to all the lectures. The congress was very successful from the viewpoint of attending media and participants and the implementation of new knowledge to practice was ascertained.

COBISS.SI-ID: 259831296Nowadays, the use of plant protection products in agriculture aims to be substituted by mechanical tools. These should in principle have a simple design, operation and use. These requirements were considered and a new tool for uprooting tuberous weeds has been developed. The tool is intended for uprooting larger tuberous weeds, which consist of a major deep root/tuber and several upper leaves, which can be very bushy (such as amaranth and broadleaf sorrel, Rumex genus). The hand-held tool consists of an ergonomically designed handle, which allows the user to convert physical force to torque moment and the removal of the root/tuber from soil. Transverse upper rollers are in contact with the soil surface and allow a minimal penetration of the tool into the soil. The scissors of the tool then remove the weed from soil in circular motion. This allows the conversion of the available physical force to torque moment and easier removal of weed plants from soil.
