Aktuelni sortiment stonih sorti i klonova vinove loze

List of table grape varieties which are actual for growing in Serbia are very traditional. Reason for that is probably relative small consumption of table grape, which are 4-5 kg per population. There is no professional or scientific justification. Large number of table grape varieties and clones of standard varieties had been created in the world and in us in last 20 years. Many grapevine varieties and clones had been imported in Serbia, and new varieties were created here in recent years. All this contributes to the higher quality and quantity offer of table grapes. If favorable ecological conditions have been added to this fact, we will have increased both production and consumption of table grape. The clones of standard table grape varieties: Afuz ali (966 and ISV 9), Muscat Hamburg (206 and 932), Muscat of Alexandria (308), Sultanina (919) and etc., with its features surpass population of varieties. Also, imported varieties: Matilda, Victoria, Michel Pallieri, Black Magic, Velika, Lival, Prima, Danlas and etc., supplemented varieties with different periods of maturation. Our new quality table grape varieties as Demir kapija, Karmen, Srbija, Lasta, etc., are found place in the standard production. Enriched grapevine list will affect that on both better production and consumption of table grape.Sortiment stonih sorti koje se trenutno masovnije gaje u Srbiji je dosta tradicionalan. Verovatno tome doprinosi i relativno mala potrošnja stonog grožđa (svega 4-5 kg / stanovniku). Za to nema ni stručnog ni naučnog opravdanja. U poslednjih 20 godina u Svetu i kod nas stvoren je veliki broj novih stonih sorti i selekcionisan veliki broj klonova standardnih sorti. Ako se ovome dodaju i povoljni ekološki uslovi naših vinogorja svi su izgledi da ćemo imati povećanu proizvodnju i potrošnju stonog grožđa. Klonovi standardnih sorti: Afuz-ali (klon 966 i ISV 9), Muskat hamburg (klon 206 i 932), Aleksandrijski muskat (klon 308), Sultanina bela (klon 919) i dr., svojim osobinama nadmašuju populaciju sorti. Takođe, introdukovane sorte Matilda, Victoria, Michel Pallieri, Black magic, Velika, Lival, Prima, Danlas i dr., dopunjuju sortiment različitog perioda sazrevanja. Naše novije vrlo kvalitetne stone sorte Demir kapija, Karmen, Srbija, Lasta i dr., već su našle mesto u sortimentu. Obogaćen sortiment i povoljni ekološki uslovi ispunjavaju predispozicije da budemo kvalitetni i produktivni proizvođači i potrošači stonog grožđa

Organsko vinogradarstvo u svetu, Srbiji i regionu

organic production is a process that develops a viable and legitimate agricultural ecosystems. The link between man, agriculture and local environmental conditions, provides quality food for people, plants and animals in a healthy environment. There are a few basic principles and ideas that explain the production of organic food in the ecosystem. The organic viticulture production in which there is a balance between environmental conditions, varieties and methods of cultivation. The two main factors that determine the choice of location concepts and establishing assortments. Organic viticulture is widespread mainly in the Mediterranean countries of Europe such as Italy, France and Spain. The Mediterranean climate with hot, dry summers and constant air currents limiting the development of pests and diseases on grapevines. The same concept can be seen in California, USA and South Africa. In the wine-growing countries with humid climates apply to another concept of organic viticulture, and that is the use of varieties resistant to pests and diseases. In Romania, Germany, Hungary, Switzerland and northern France are represented interspecific hybrids and new resistant varieties. In the north-east of America, on the border with Canada, grown varieties Vitis labrusca and Vitis species in the south rotundifolia. However, in these humid regions is crucial in the selection of sites with appropriate climatic and soil conditions. The choice of suitable climatic conditions is important for conventional viticulture in order to get the best quality of grapes and wine.Organska proizvodnja je proces koji razvija održive i opravdane agroekosisteme. Povezanost čoveka, poljoprivrede i lokalnih ekoloških uslova, pruža kvalitetnu hranu za ljude, biljke i životinje u zdravoj životnoj sredini. Postoji nekoliko osnovnih principa i ideja koji objašnjavaju proizvodnju organske hrane u ekosistemu. Organsko vinogradarstvo je proizvodnja u kojoj postoji ravnoteža između ekoloških uslova, sorte i načina kultivacije. Dva osnovna faktora koji određuju koncepte su odabir lokacije i utvrđivanje sortimenata. Organsko vinogradarstvo je široko rasprostranjeno uglavnom u mediteranskim zemljama Evrope kao što su Italija, Francuska i Španija. Mediteranska klima sa toplim i suvim letima i stalnim vazdušnim strujama ograničava razvoj bolesti i štetočina na vinovoj lozi. Isti koncept se ogleda u Kaliforniji, SAD-u i Južnoj Africi. U vinogradarskim zemljama sa humidnom klimom primenjuje se drugi koncept organskog vinogradarstva, a to je primena otpornih sorata na bolesti i štetočine. U Rumuniji, Nemačkoj, Mađarskoj, Švajcarskoj i Severnoj Francuskoj zastupljeni su interspecies hibridi i nove otporne sorte. Na severo-istoku Amerike, na granici sa Kanadom, gaje se sorte vrste Vitis labrusca, a na jugu vrste Vitis Rotundifolia. Međutim, u ovim humidnim oblastima presudan je izbor lokacije sa odgovarajućim klimatskim i zemljišnim uslovima. Izbor pogodnih klimatskih uslova je važan i za konvencionalno vinogradarstvo kako bi se dobili najbolji kvalitet grožđa i vina

A study was conducted during three years (2009 - 2011) to evaluate the cropping potential and quality of the grape variety Cabernet franc cultivated in the Trstenik vine growing region. The data obtained showed that Cabernet franc can be successfully grown under the environmental conditions of the Trstenik vine growing region as it produced good yields of high quality grape. Over the three-year period, the average yield per hectare was about 10 t, with the sugar and total acids contents being 200 g l-1 and 6.9 g l-1 respectively, suggesting optimum growing conditions for this variety in the study region.U uslovima trsteničkog vinogorja u periodu 2009 do 2011. godine ispitivan je rodni potencijal i kvalitet grožđa sorte Kaberne fran. Rezultati pokazuju da se sorta Kaberne fran može uspešno gajiti u agroekološkim uslovima trsteničkog vinogorja. Sorta je iskazala dobru rodnost i dobar kvalitet grožđa. Prosečan prinos po hektaru u trogodišnjem periodu kretao se oko 10 t, sadržaj šećera bio je 200 g l-1 dok je ukupnih kiselina bilo 6,9 g l-1, što znači da je ispitivana sorta imala optimalne uslove za gajenje u ovom vinogorju

Uticaj alkoholne fermentacije na kvalitet rakije lozovače

Grape brandy is a product obtained by fermentation and distillation of crushed grapes of cultivated grapevine Vitis vinifera. Grape brandy quality depends on many factors such as: grapevine varieties, climate, soil, time and method of distillation, storage methods and other distillates. The grapevine variety 'Neoplanta' grown in the experimental field of the PD 'Center for Viticulture and Enology' in Niš was used in the experiment. Tests were performed in the laboratory of the Centre. Healthy grapes of harvest maturity were squashed by a stalk-removing electric crusher. Fermentation was performed in plastic containers in the presence of the indigenous microflora of wine yeasts. This paper presents the influence of pH and inorganic nitrogen added to the fermentation medium on the content of volatile components and concentrations of higher alcohols.Lozovača ili lozova rakija predstavlja proizvod koji se dobija fermentacijom i destilacijom celog kljuka grožđa plemenite vinove loze Vitis vinifera. Kvalitet rakije lozovače zavisi od velikog broja faktora: sorte vinove loze, klime, zemljišta, vremena i načina destilacije, načina čuvanja destilata i dr. Za realizaciju ovog eksperimenta korišćeno je grožđe sorte vinove loze 'Neoplanta' koja se gaji na oglednom imanju PD 'Centar za vinogradarstvo i vinarstvo' u Nišu. Ispitivanja su izvedena u laboratorijskim uslovima Centra. Zdravo i tehnološki zrelo grožđe je izmuljano električnom muljačom koja odvaja peteljke. Fermentacija celokupnog kljuka grožđa je izvršena u plastičnim vrionim posudama u prisustvu autohtone mikroflore vinskih kvasaca. U radu je prikazan uticaj pH vrednosti i neorganskog azota dodatog u fermentacionu smešu na sadržaj isparljivih komponenti i koncentraciju viših alkohola

Ampelografski opis grozda, bobice i semenke sorte Merlo (Vitis vinifera L.) - i odabranih klonova

During a four-year period, ampelographic experiments focusing on the berry cluster (average length of grape cluster, number of grape clusters per shoot, number of berries per grape cluster and length of peduncle), berry (length of berry and berry juice yield), length of pedicel and seed (length of berry seed) of Merlot cultivar (used as a relevant standard) and 11 clones (Nos. 022, 023, 025, 026, 027, 028, 029, 030, 031, 033 and 034) were performed in order to establish the differences among them. These experiments were actually conducted in the third phase of individual clonal selection of Merlot cultivar carried out in Serbia. The lengths of grape cluster and pedicel as well as berry must yields differed significantly among the examined clones. The cluster and principal component analyses classified 12 samples into three divergent clusters/groups, respectively. The clones belonging to the cluster II /the second group/ had significantly higher values of numbers of grape clusters per shoot and berries per grape cluster; lengths of peduncle and berry; berry must yield and length of pedicel, compared both to standard Merlot /the cluster I, the first group/ and the clones of the cluster III /the third group/. The phenological observations showed no significant differences in the beginnings and durations of phenological stages and vegetation period of the examined clones. The obtained results indicate the real need for further research work focused both on the agrobiological and technological properties of the grapes and wines aiming to better describe the selected clones.Tokom četvorogodišnjeg perioda urađen je ampelografski opis grozda, bobice i semenke jedanaest klonova (022, 023, 025, 026, 027, 028, 029, 030, 031, 033 i 034) i sorte Merlo (kao standarda) u cilju utvrđivanja razlike među njima. Datim ispitivanjem (sprovedenim u Srbiji) obuhvaćene su sledeće karakteristike: broj grozdova po izdanku, dužina grozda, broj bobica po grozdu, dužina stabljike grozda, dužina bobice, randman soka bobice, dužina peteljčice bobica i dužina semenke. Eksperimenti su urađeni u toku treće faze individualne klonske selekcije sorte Merlo. Proučavani klonovi značajno su se razlikovali među sobom, a posebno prema dužini stabljike grozda, randmanu soka bobice i dužini peteljčice bobice. Dobijeni rezultati obrađeni su hijerarhijskom klasterskom analizom (HCA) i multivarijantnom analizom podataka (pomoću analize glavnih komponenata - PCA). Shodno tome, dati uzorci (standard i varijeteti) svrstani su u tri klastera (HCA), odnosno grupe (PCA). Klonovi obuhvaćeni klasterom II /druga grupa/ odlikovali su se značajno većim vrednostima broja grozdova po izdanku, broja bobica po grozdu, dužine stabljike grozda, dužine bobice, randmana soka bobice i dužine peteljčice bobice kako u odnosu na Merlo standard, tako i u odnosu na klonove klastera III /treća grupa/. Kao takvi, mogu biti obuhvaćeni daljim proučavanjima u okviru klonske selekcije. Sa fenološkog aspekta, pak, među datim klonovima nisu uočene značajnije razlike u početku i trajanju pojedinačnih razvojnih fenofaza, kao i u dužini vegetacionog perioda
