AB  - The objective of this study was to develop phenological models capable of predicting the onset of veraison and harvest in grapevine early enough to be useful for viticultural activities planning. Models are based on the responsiveness of phenological timing to the preceding thermal conditions. Key temperature variable and period for the onset of veraison and harvest were determined using the long-term (1981-2007) temperature and phenological data for 20 wine cultivars grown in the region of Sremski Karlovci (Serbia). The input variable for both phenological models was the maximum daily temperature averaged over the period from April 1 to June 30. The general model equations set up for grapevine as a species were adjusted for each cultivar by adding a correction factor. The correction factor was calculated as a difference between the mean date of phenological stage onset for given cultivar and the average value for all examined cultivars. The proposed empirical models proved to be capable of predicting the onset of veraison and harvest in grapevine cultivars with high accuracy, up to one and half month ahead for veraison and up to three months for harvest. On average for all cultivars, the mean absolute differences between the observed and predicted veraison and harvest dates were 4 and 6 days, respectively. The results are very satisfactory, having in mind the high year-to-year variability of veraison date (up to 49 days) and harvest date (up to 64 days) during the studied period.

AB  - Heat requirements for four major phenological stages (budburst, flowering, veraison and harvest) were assessed in eight red grapevine cultivars grown in the Sremski Karlovci region in northern Serbia using a growing degree-days (GDD) method and base temperature of 10 degrees C. Temperature and phenological data covering the period 1986-2007 were used to conduct the study. The accumulated GDD for the beginning of budburst ranged from 70 ('Gamay' and 'Limberger') to 92 ('Cabernet Sauvignon'). The heat requirements for the beginning of flowering varied between 338 GDD in 'Gamay' to 398 GDD in 'Probus'. The smallest heat requirements to reach the beginning of veraison was observed in 'Portugizer' (937 GDD) and the greatest in 'Probus' (1117 GDD). The GDD for harvest spanned the range from 1555 in 'Portugizer' to 1649 in 'Prokupac'. Generally, a greater variation in GDD was found between years for a single cultivar than among cultivars within individual years. Among phenological stages, the greatest inter-annul variation in terms of coefficient of variation was displayed for the beginning of budburst and the least for harvest.

AB  - The historical temperature (1981-2007) and phenological (1986-2011) data were analysed for the region of Sremski Karlovci, one of the oldest grapevine growing areas in Europe, with the aim of detecting trends of changes in the data, evaluating the sensitivity of grapevine phenology to temperature and revealing diversity among cultivars in their response to observed changes in temperature. The onset dates of four major phenological stages (budburst, flowering, veraison and harvest), along with the corresponding growth intervals between them, were examined for 20 wine grape cultivars. A number of climatically important parameters for viticulture were calculated for the calendar year, growing season and different grapevine growth periods. Significant increases were detected in average and heat-related extreme temperature indices. The greatest rate of change in temperature variables across the growing season was observed during the period from the beginning of flowering to the beginning of veraison and the smallest during the ripening period. Linear trends indicated that all phenological stages, except budburst, have advanced significantly. Averaged across all cultivars, detected trends were -0.4, -0.7 and -0.6 days/year for the beginning of flowering, the beginning of veraison and harvest date, respectively. Observed warming and change in the timing of phenological events did not significantly affect the duration of the growth intervals, which can be explained by significant inter-correlation between the phenological stages' onset. Ripening was occurring under warmer conditions due to earlier flowering and veraison, rather than because of considerably higher temperatures preceding harvest or shortening of the ripening period. Most of the variation in phenology timing (74-90%) can be explained by a linear relationship between the onset date of phenological stage and temperature, with mean and maximum temperatures being more important than minimum temperatures. According to the current results, a 1 degrees C increase in the most influential temperature variable during the most relevant periods for the onset of phenological stages led to an advancement in the beginning of budburst, the beginning of flowering, the beginning of veraison and harvest by 3.6, 3.1, 5.2 and 7.4 days, respectively, on average for all cultivars. Among the cultivars studied, Pinot Noir displayed the greatest phenology advancement in response to increased temperature.

AB  - The objective of this study was to evaluate diversity and relationships among grapevine cultivars from the Serbian gene bank in Sremski Karlovci, and to identify the most useful variables for discrimination. A total of 54 grapevine cultivars have been studied. During the period 2000-2005, twelve quantitative and qualitative characteristics were evaluated using OIV categories to each trait. Characterization was done using multivariate statistical analyses: cluster and principal component analysis (PCA), Based on cluster analysis cultivars divided into three major groups and the clustering pattern was related to the classical eco-geographical grouping: occidentalis, pontica and orientalis. Beside geographic origin clustering position of cultivars throughout the dendrogram was related to main uses. The major part (70.1%) of the total variation presented was explained by four principal components. PC1 is highly correlated with the bunch and berry size and PC2 with the density of prostrate hairs of young shoot tip and the density of prostrate hairs between veins on the lower side of mature leaf. The overall arrangement of cultivars suggests considerable phenotypical (and presumably genetic) variability in studied germplasm collection. Furthermore, obtained results may be useful for further utilization of available genetic resources in gene bank managers, growing and breeding.

AB  - A comprehensive analysis of phenological timing and growth intervals for eight red and thirteen white wine grape cultivars in the region of Sremski Karlovci was performed using a long-term (1986-2011) data set. Four phenological stages of grapevine were examined: beginning of budburst, beginning of flowering, beginning of veraison and harvest. The phenological stages studied exhibited a 30 to 51 day variation between the earliest and latest years for red cultivars and 29 to 49 day variation for white cultivars. The beginning of flowering exhibited the least, while harvest showed the highest inter-annual variation. The difference between red and white cultivars was the greatest for harvest - the mean harvest date averaged over all red cultivars was 24 September and over all white cultivars 14 September. The beginning of flowering to the beginning of veraison interval showed the smallest and budburst to harvest interval the greatest year-toyear variability. The beginning of budburst to harvest period for the cultivars examined averaged 165 days for red and 156 days for white cultivars, with the mean interval range of 58 days for red and 55 days for white cultivars. In addition, it was found that a variability of the onset and duration of phenological phases was greater between years for a single cultivar than among cultivars within individual years, meaning that climatic factors are more important than genetic characteristics of cultivars for phenological timing.

Ispitivana su četiri fenološka događaja: otvaranje pupoljaka, početak cvetanja, početak šarka i berba. Amplituda između najranijeg i najkasnijeg nastupa proučavanih fenoloških događaja kretala se od 30 do 51 dan za crvene i od 29 do 49 dana za bele sorte. Najmanje variranje između godina pokazao je datum početka cvetanja, a najveće datum berbe. Najveća razlika između crvenih i belih sorti je utvrđena kod datuma berbe - srednji datum berbe bio je 24. septembar za crvene, a 14. septembar za bele sorte.

Po godinama, trajanje ove fenološke faze variralo je u proseku 58 dana za crvene i 55 dana za bele sorte. Takođe je ustanovljeno da na variranje nastupa i trajanja fenoloških faza veći uticaj imaju klimtski faktori nego genetske osobine sorti.

Consistent matching with SSR markers of grapevines cultivated in neighbouring countries or maintained in European germplasm collections was found for most of the genotypes, suggesting possible synonyms and revealing that 'Muskat Krokan' corresponds to 'Muscat fleur d'Oranger' and two 'Tamjanika' cultivars are identical to 'Moscato Giallo' and 'Moscato Rosa'. When compared with germplasm representing the classical eco-geographic grouping of grapevine cultivars, Serbian non-Muscat genotypes clustered within the Convar pontica subconvar balcanica taxon thus supporting their indigenous origin.

AB  - The purpose of this paper was to characterize the clones obtained from Kreaca, autochthonous grapevine cultivar of Banat. Based on examination of 6 important biological and technological properties, phenotypic and genetic divergence of 28 selected clones was established. The divergence was determined using ANOVA and hierarchical cluster analysis. Using variance analysis, for grape weight, yield, total acid content, sugar content and sugar/acid ratio very significant or significant differences were obtained between clones. The UPGA method was used and the Euclidean distance in order to determine the difference between the groups. Two clone groups were obtained on the dendrogram. The objective of clone differentiation was primarily cluster weight, although other properties were taken into account as well. As the most perspective clones for further investigation and production, that can be recommended, were clones 12/5/5, 56/11/7 and 69/11/7.

Sa ukupne površine od 12 ha, na osnovu šest značajnih bioloških i tehnoloških karakteristika izdvojeno je 28 klonova. Primenom ELISA testa kod svih ispitivanih klonova nije utvrđeno prisustvo sledećih ekonomski značajnih virusa: Nepovirus Grapevine fanleaf virus (GFLV), clostero virusa, Grapevine leafroll-associated virus 1(GLRaV-1), Grapevine leafroll-associated virus 2(GLRaV-2) i Grapevine leafroll-associated virus 3(GLRaV-3). Primenom ANOVA i hijerarhijske klaster analize određena je divergentnost klonova. Analizom varijanse ustanovljene su veoma značajne ili značajne razlike između klonova za masu grozda, prinos, sadržaj ukupnih kiselina, sadržaj šećera i odnos šećera i kiselina. Fenotipska divergentnost između klonova ustanovljena je primenom hijerarhijske klaster analize. Korišćen je UPGA metod, pri čemu je razlika između grupa izražena preko Euklideanovog rastojanja.

AB  - The objective of this study was to assess the effect of bud load and the green foliage they produce on the yield and quality of grapes and wine of the cultivar 'Liza'. Three levels of bud loading, i.e., canopy density, were applied. The first variant of bud loading was 2 bud spurs and a cane with 12 buds, or 11.7 shoots per meter of canopy length. The second variant of bud loading was two canes each with 12 buds, or 20 shoots per meter of canopy length. The third variant of bud loading was two canes each with 17 buds, or 28 shoots per meter of canopy length. Influence of meteorological parameters on these cultivar features was also monitored. Ripening dynamics and grape and wine quality were observed through the test years. Based on long-term investigations and the results of this study, it was concluded that the increased bud load and canopy density, with the applied small plant distances in the row, decreased the (potential) bud fertility, grape yield, and grape and wine quality.

AB  - The aim of this investigation was to find out the influences of heat and water precipitations on the potential fertility differentiation, which happens with buds necessary for next pruning, from the middle May until the beginning of July. Investigations which started in 1997. are still carrying out at the Experimental Field of the Institute for Fruit Growing, Viticulture, and Horticulture, Faculty of Agriculture, Novi Sad, which lies in the northern part of Fruska Gora vineyard area, in Sremski Karlovci- Serbia. New designed cultivars Sila, Nova Dinka and Riesling Italian clone SK-13 were examined. By counting the inflorescences on the example of 15 grape vines per variant, coefficients of fertility per cultivar were calculated, and their values per years were compared. By analyzing meteorological factors (heat and water) and coefficients of fertility for the examined period, exceptional connection between them was established. In the years when there was a lot of rain in the May and June, and when they were followed by low temperatures in this period, potential fertility or fertility for the next year, was very low. In some cases it was 50 and more % lower then average values. In the years when temperature conditions, and water precipitations in the May and June were good, next year, coefficients of fertility in all buds were high. To reduce negative influence of bad weather in some years, grapegrowers must help to the grape vine by using all measures of agro and especially phitotechnique. .
AB  - Cilj ovog istraživanja je bio da se utvrdi uticaj toplote i padavina na izgradnju moguće rodnosti, koja se u okcima potrebnim za rezidbu, odvija od sredine maja pa do početka jula. Istraživanja koja su počela 1997. su još uvek u toku, na Oglednom Polju Departmana za voćarstvo, vinogradarstvo, hortikulturu i pejzažnu arhitekturu, u Sremskim Karlovcima. Ispitivane su novostvorene sorte sila, nova dinka, grašac beli (ital. rizl.) klon 13, petra i liza. Utvrđivanjem rodnosti na po 15 čokota po varijanti, izračunati su koeficijenti rodnosti, i potom je urađeno njihovo upoređivanje po godinama.

abstract = "The aim of this investigation was to find out the influences of heat and water precipitations on the potential fertility differentiation, which happens with buds necessary for next pruning, from the middle May until the beginning of July. Investigations which started in 1997. are still carrying out at the Experimental Field of the Institute for Fruit Growing, Viticulture, and Horticulture, Faculty of Agriculture, Novi Sad, which lies in the northern part of Fruska Gora vineyard area, in Sremski Karlovci- Serbia. New designed cultivars Sila, Nova Dinka and Riesling Italian clone SK-13 were examined. By counting the inflorescences on the example of 15 grape vines per variant, coefficients of fertility per cultivar were calculated, and their values per years were compared. By analyzing meteorological factors (heat and water) and coefficients of fertility for the examined period, exceptional connection between them was established. In the years when there was a lot of rain in the May and June, and when they were followed by low temperatures in this period, potential fertility or fertility for the next year, was very low. In some cases it was 50 and more % lower then average values. In the years when temperature conditions, and water precipitations in the May and June were good, next year, coefficients of fertility in all buds were high. To reduce negative influence of bad weather in some years, grapegrowers must help to the grape vine by using all measures of agro and especially phitotechnique. ., Cilj ovog istraživanja je bio da se utvrdi uticaj toplote i padavina na izgradnju moguće rodnosti, koja se u okcima potrebnim za rezidbu, odvija od sredine maja pa do početka jula. Istraživanja koja su počela 1997. su još uvek u toku, na Oglednom Polju Departmana za voćarstvo, vinogradarstvo, hortikulturu i pejzažnu arhitekturu, u Sremskim Karlovcima. Ispitivane su novostvorene sorte sila, nova dinka, grašac beli (ital. rizl.) klon 13, petra i liza. Utvrđivanjem rodnosti na po 15 čokota po varijanti, izračunati su koeficijenti rodnosti, i potom je urađeno njihovo upoređivanje po godinama. Analiziranjem i meteoroloških činilaca i koeficijenata rodnosti u ispitivanom periodu, utvrđena je izuzetna povezanost, ili uslovljenost. U godinama kada je u maju i junu bilo dosta kiše, koje su praćene niskim temperaturama, potencijalna rodnost je bila veoma niska. U pojedinim slučajevima ona je bila 50% i više posto niža nego prosečna. U godinama kada su toplotni uslovi i količina padavina u maju i junu bili povoljni, koeficijenti rodnosti su bili visoki. Da bi se sprečio negativan uticaj lošeg vremena u pojedinim godinama, vinogradari moraju pomoći vinovoj lozi posebnim agro i fitotehničkim merama. .",

AB  - Cultivars Sila and Riesling Italian are included in investigation dedicated to the influence of operations of summer pruning, to the technological characteristics and cold hardiness of some wine grape cultivars. Vineyard with cultivar Sila, grafted on Kober 5BB rootstock, where investigations are performing, was planted in 1998, at the Experimental Field of Faculty of Agriculture Novi Sad, placed at the Sremski Karlovci. Vineyard where investigations with cultivar Riesling Italian, grafted on rootstock 5BB are performing, was planted in 1996, and it is located nearby. Planting distances are 3,0 x 1,6 m with Sila, and 2,8 x 1,6 m with Riesling Italian, and because of that differences, bud loading was equaled on 6,25 buds/m2. All known operations of summer pruning were performed during the vegetation, but, there is one non performed in vineyards, and that is cluster removing from laterals. This is very important, because this grape never ripens, and needs to much nutrients, that are necessary for the grapes on the main shoots, for their ripening, and their preparing for the winter. In the period of harvesting, all data connected with the yield were collected, and the experimental wines were produced. Cold hardiness investigation, in cold chamber, started at the beginning of winter. Applied temperature was -20°C in the period of 10 hours. After very low temperatures appearance in nature conditions (-17,4°C), in the winter 2004/2005, samples were collected from vineyards, for establishing real damages. Wine testing was organized at the end of winter 2004/05. Experimental results point out on exceptionally favorable green operations influence, especially additional yield removing from laterals, on grape and wine quality, and enhanced resistance to low temperatures.
AB  - U okviru ogleda, koji je postavljen da bi se utvrdio uticaj operacija zelene rezidbe na privredno tezhnološke karakteristike i otpornost prema niskim temperaturama kod nekih sorti vinove loze, nalaze se i sorte sila i rizling italijanski. Vinograd sa sortom sila, kalemljenom na podlozi kober 5BB, u kome je postavljen ogled, je posađen 1998. godine, na Oglednom polju Instituta za voćarstvo, vinogradarstvo i hortikulturu u Sremskim Karlovcima. Primenjen je razmak sadnje od 3,0 h 1,6 m, tj. sadnja u paru, i rezidba, ostavljanjem jednog kondira od 2 okca, i jednog luka od 13 okaca po čokotu, što daje 6,25 okaca/m2. Vinograd sa sortom rizling italijanski klon 54, kalemljenom na podlozi kober 5BB, gde je takođe postavljen ogled, je posađen nedaleko od prethodnog, 1996. godine. Primenjeni razmak sadnje je 2,8 h 1,6 m, a rezidbom su ostavljani jedan kondir od 2 okca i luk od 12 okaca, što daje 6,25 okaca/m2. U toku vegetacije 2004. god. su primenjene sve uobičajene fitotehničke mere, i što je najvažnije nešto što se u vonogradima ne radi, a to je uklanjanje dopunskog roda sa zaperaka. Ovo je posebno važno jer taj rod skoro nikada ne sazri, a "odvuče" veliku količinu hranljivih materija potrebnih biljci za sazrevanje roda na glavnim lastarima, i za pripremu loze za zimu. U vreme berbe su prikupljeni svi podaci vezani za prinos, a početkom zime je počelo ispitivanje otpornosti prema niskim temperaturama u hladnoj komori na temperaturi od -20°C, dok su posle nastupanja ekstremno niskih temperatura u prirodnim uslovima, uzeti uzorci iz vinograda, da se utvrde prave štete. Pred kraj zime je organizovana proba vina proizvedenih iz ovog ogleda. Rezultati ukazuju na izuzetno povoljan uticaj operacija zelene rezidbe, a pogotovo uklanjanje dopunskog roda sa zaperaka, na kakvoću grožđa i vina, i povećanje otpornosti vinove loze, prema ekstremno niskim zimskim temperaturama.
