This thesis deals with designing a wine hotel for Nikolsburg winery in Mikulov. The goal was to design a hotel which incorporates storage and processing of wine, while complimenting the surrounding vineyard landscape. The site is situated between nature reserves Turold nad Růžový vrch. The main focus of the design was to allow for the best possible view of surrounding vineyards, Mikulov Chateau, Basilica in Svatý kopeček and Turold nature reserve. The work centers around 4-star hotel able to accommodate 30 people, which includes a restaurant, small wellness for hotel guests and suitable technical facilities. Additionaly, the building is equipped for clean wine production (fermentation, pressing, aging, bottling, labelling, storage and expedition) and features a degustation room. Basic concept of the hotel was derived from the slope of the terrain, viewing axes and geographic orientation. There is a number of terraces symbolizing moravian hills covered by vineyards, which offer guests unobscured view of the surrounding landscape (and investors vineyards). The whole operation of the hotel has to do with winemaking as is seen in the building design. Vertical features of the facade represent rows and vertical poles in vineyards.

The goal of the diploma thesis is to design a wine hotel for 30 people with other public spaces with quality accommodation corresponding to the level of four stars in Mikulov. The new building of the Wine House is a three-storey building located in a sloping terrain, which consists of three floors above ground and one underground floor. The wine house will provide Nikolsburg Winery as a representative building. Visitors and guests of the hotel can enjoy a glass of wine on the terrace of the proposed building and at the same time wonderful views of the vineyards and the silhouette of Mikulov, relax in the surrounding picturesque landscape, or visit the nearby center of Mikulov, Pálava hills or take a boat ride on the surface of reservoirs called Novomlýnské nádrže. Accommodated guests will have the opportunity to use the wellness, massage and Finnish sauna. Tourists passing by will have the opportunity to taste good food and visit the wine lounge, where they can taste and buy locally produced wine at the same time.

This diploma thesis drafts concept of winery based on business network of small wineries using synergetic effect. Critical analysis of macro and micro environment together with explorative research of small wineries was used as a starting point. Based on obtained information, concept of mentioned winery is proposed as an outcome of this thesis.

Vineyards in the Mid-Atlantic often have large, vigorous vines that can be costly to manage and produce inadequate fruit for wine production. Dense canopies increase the incidence of fungal disease, require greater allocation of resources to manage, and inhibit fruit development. The primary objective of these studies was to determine effective vine-size modification treatments that would optimize fruit quality, while reducing labor and chemical control. Research factors included root manipulation, under-trellis ground cover, and rootstock. Treatment levels were root bag (RBG) or no root manipulation (NRM); under-trellis cover crop (CC) or herbicide strip (HERB); and one of three rootstocks: 101-14, Riparia Gloire, or 420-A. Effects of these treatments were measured in two experiments: Experiment I compared combinations of all three treatments, while Experiment II explored the individual effects of root restriction using root bags of varying volumes. Root restriction consistently demonstrated the ability to reduce vegetative growth and vine water status. In the first experiment fruit-zone photosynthetic photon flux density (PPFD) was increased by 234% in RBG vines. Timed canopy management tasks indicated that RBG canopies required about half the labor time of NRM canopies. Anthocyanin concentration and total phenolic content were increased by 20% and 19% respectively in RBG fruit. CC increased fruit-zone PPFD by 62%, and increased soluble solids and color compounds. The 420-A rootstock reduced potassium uptake, resulting in lower must potassium concentration. Results demonstrated that these treatments significantly reduce vegetative growth in a humid climate, decrease management labor, and produce higher quality fruit. / Master of Science / Vineyards in the Mid-Atlantic often have large, vigorous vines that can be costly to manage and produce inadequate fruit for wine production.

Timed canopy management tasks indicated that RBG canopies required about half the labor time of NRM canopies. Sugar and color concentration were both increased in RBG fruit. CC also increased sunlight exposure, as well as sugar and color concentration. The 420-A rootstock reduced potassium uptake, resulting in lower must potassium concentration.

La tesi si basa sui principi della sostenibilità ambientale applicati al settore della viticultura. I principali obiettivi sono: i) analisi della letteratura riguardante gli indicatori agro-ambientali, ii) sviluppo di una metodologia innovativa per valutare l’impatto ambientale della viticultura e, iii) applicazione della metodologia in casi pratici. La parte introduttiva è dedicata all’analisi degli indicatori agro-ambientali e delle relative politiche europee, alle tematiche inerenti il vino sostenibile e i sistemi di supporto alle decisioni per una viticultura sostenibile. Nella seconda parte è presentata una rigorosa e completa metodologia per valutare il livello di sostenibilità in tutte le fasi della produzione di uva, usando sia indicatori agronomici sia l’approccio della valutazione del ciclo di vita (Life Cycle Assessment). Sono state identificate sei categorie di impatto: salute umana, aria, suolo, biodiversità, consumi energetici e uso dell’acqua. Ogni categoria è composta da sotto-indicatori, per un totale di 21 sotto-indicatori, ognuno dei quali avente un punteggio (da 0 a 5) e un peso relativo nel punteggio complessivo di sostenibilità (da 0 a 5). La terza parte riguarda l’applicazione della metodologia in casi studio all’interno del progetto europeo “InnoVine”. Il lavoro di ricerca è stato realizzato seguendo le linee guida di standard internazionali e documentate fonti di letteratura per la valutazione della prestazione ambientale ed elaborando metodologie originali per la raccolta dei dati, la quantificazione degli impatti e l’interpretazione dei risultati. Infine, i risultati ottenuti confermano: i) la validità della metodologia nel calcolare gli impatti delle differenti pratiche viticole sull’ambiente e, ii) la possibilità di implementare la metodologia in un sistema di supporto alle decisioni per una viticultura sostenibile. / The thesis focuses on environmental sustainability principles applied to the viticultural sector. The main goals are: (i) analysis of the literature background on agri-environmental indicators, (ii) development of an innovative methodology to assess environmental impacts of viticulture, and (iii) testing of the methodology in practical cases. The introduction is dedicated to the analysis of the agri-environmental indicators and the related EU policies, sustainable wine issues, and decision support systems for a sustainable viticulture. In the second part, a rigorous and complete methodology is developed to assess the sustainability level of viticulture in all the phases of the grape growing using both agronomic indicators and the Life Cycle Assessment approach. Six impact categories were identified: human health, air, soil, biodiversity conservation, energetic consumptions, and water use. Each category is composed by sub-indicators, for a total of 21 sub-indicators, each of them having a score (between 0 and 5) and a defined weight on the overall sustainability score (between 0 and 5). In the third part, the methodology was tested in practical cases within the European project “InnoVine”. The study is carried out following the guidelines from international standards and from documented literature sources for the assessment of the environmental performance and elaborating original methodologies for the input data collection, the quantification of the impacts, and the interpretation of the results. Finally, the results obtained confirm: i) the methodology validity in quantifying the impacts of different grape production practices on the environment, and ii) the possibility to implement the methodology in a decision support system for a sustainable viticulture.

Thesis (MScAgric)--Stellenbosch University, 1999. / ENGLISH ABSTRACT: The purpose of the study is to determine the rate of return to cover crop research in the wine industry. The method followed will prove an invaluable contribution toward the need to determine a suitable approach for evaluation studies. The importance behind such a study is the development of appropriate ex ante evaluation approaches, which will assist in the allocation of public research resources in both a social and economical manner. The wine industry is currently enjoying healthy international demand, but will need to remain competitive to reap the full benefit of international exposure. The need therefore exists for a continuation of research at the institutional level, in order to maintain the progressive nature of research knowledge that was available in the past. The evaluation of ex post and ex ante research will assist in maintaining government funding for research and help with campaigning for private investment of research in the wine industry. The use of two evaluation approaches was used for the analysis. Firstly, the production function approach achieved a rate of return of 44 percent, using weather and research expenditure as a means to explain the variations in wine grape yield. Secondly, a cost benefit approach was devised in order to make a direct comparison between the cost and benefits related to the cover crop research. The rate of return achieved for this mode of analysis is 37 percent, using trial plot data as a source of information on potential benefits. In addition to this the cost benefit approach was used to show the difference in rate of return that is achievable between two growing regions. The variable that exists between the two regions, is the higher rate of irrigation in one of the regions. The high rate of return achieved for the investment, provides suitable motivation for the increase in state funding for research in the wine industry, and provides valuable information for the enticement of support by private investors. The two methods used in the study will both draw a certain amount of criticism, largely as a result of the lack of available data. The empirical nature of the approaches is however simple and applicable down to the project level. / AFRIKAANSE OPSOMMING: Die doel van hierdie studie is om die opbrengs op navorsing oor dekgewasse in die Suid- Afrikaanse wynbedryf te bepaal. Hierbenewens het die studie dit ook ten doel om gepaste metodieke vir die evaluering van navorsingsprojekte daar te stel. In hierdie opsig maak hierdie studie ' n bydrae tot besluitneming oor die allokering van openbare fondse vir landbounavorsing op 'n ekonomies en sosiale optimale wyse. Die Suid- Afrikaanse wynbedryf beleef tans ' n bloeifase, hoofsaaklik as gevolg van sterk internasionale vraag na sy produkte, maar salop sy internasionale mededingendheid moet let indien die volle voordele hiervan benut kan word. Daarom is dit noodsaaklik dat die bedryf op tegnologiese gebied moet kan meeding, en dus dat navorsingsbesteding nie onoordeelkundig ingekort word rue. Inligting oor die opbrengs op navorsingsbesteding is dus noodsaaklik om die volgehoue betrokkenheid van die staat te kan regverdig, hetsy as finansier of as katalisator vir privaatsektor betrokkenheid. In hierdie studie is die opbrengs op navorsing gemeet deur beide die bekende produksiefunksie benadering sowel as deur koste-voordeel ontleding. In die eerste geval is 'n opbrengskoers van 44% gemeet, en in die tweede geval is dit 37%. By die kostevoordeel ontleding is ook 'n verdere onderskeid gemaak tussen twee wynbou-streke om die invloed van meer besproeiing te bepaal. Ten spyte van dataprobleme, veral wat betref die koste van navorsing, kan beweer word dat die inligting so verkry van nut sal wees vir besluitnemers by die toekenning van skaars navorsingsfondse, asook by bedinging om privaatsektor fondse.

In this study, buckwheat (Fagopyrum esculentum Moench) and alyssum (Lobularia maritima (L.)) flowers were used to examine the effect of floral resources on the efficacy of the leafroller parasitoid Dolichogenidea tasmanica (Cameron) in vineyards. This was done by assessing the influence of these flowers on parasitoid abundance and parasitism rate, and by investigating the consequences of this for leafroller abundance. In laboratory experiments, alyssum flowers were used to investigate the effect of floral food on the longevity, fecundity and sex ratio of D. tasmanica. Dolichogenidea tasmanica comprised more than 95 % of parasitoids reared from field collected leafrollers in this study. The abundance of D. tasmanica during the 1999-2000 growing season was very low compared with previous studies, possibly due to the very low abundance of its leafroller hosts during the experiment. The number of males of this species on yellow sticky traps was increased (although not significantly) when buckwheat flowers were planted in a Marlborough vineyard; however, the number of female D. tasmanica on traps was no greater with flowers than without. The abundance of another leafroller parasitoid, Glyptapanteles demeter (Wilkinson)(Hymenoptera: Braconidae), on traps was also not significantly affected by the presence of buckwheat flowers, although females of this species were caught in greater numbers in the control than in buckwheat plots. Naturally-occurring leafrollers were collected from three vineyard sites in Marlborough, and one in Canterbury during the 2000-2001 season to assess the effect of buckwheat and alyssum flowers on parasitism rate. Parasitism rate more than doubled in the presence of buckwheat at one of the Marlborough vineyards, but alyssum had no effect on parasitism rate in Canterbury. A leafroller release/recover method, used when naturally-occurring leafrollers were too scarce to collect, was unable to detect any effect of buckwheat or alyssum on parasitism rate. Mean parasitism rates of approximately 20 % were common in Marlborough, although rates ranged from 0 % to 45 % across the three vineyard sites in that region. In Canterbury in April, mean parasitism rates were approximately 40 % (Chapter 4). Rates were higher on upper canopy leaves (40-60 %) compared with lower canopy leaves and bunches (0-25 %). Leafroller abundance was apparently not affected by the presence of buckwheat in Marlborough, or alyssum in Canterbury. Buckwheat did, however, significantly reduce the amount of leafroller evidence (webbed leafroller feeding sites on leaves or in bunches) in Marlborough, suggesting that the presence of these flowers may reduce leafroller populations. Leafrollers infested less than 0.1 % of Cabernet Sauvignon leaves throughout the 1999-2000 growing season, but increased in abundance in bunches to infest a maximum of 0.5 % of bunches in late March in Marlborough. In Pinot Noir vines in the 2000-2001 season, leafroller abundance was also low, although sampling was not conducted late in the season when abundance reaches a peak. In Riesling vines in Canterbury, between 1.5 % and 2.5 % of bunches were infested with leafrollers in April. In the laboratory, alyssum flowers significantly increased the longevity and lifetime fecundity of D. tasmanica compared with a no-flower treatment. However, daily fecundity was not increased by the availability of food, suggesting that the greater lifetime fecundity was related to increases in longevity. Parasitoids were also able to obtain nutrients from whitefly honeydew, which resulted in similar longevity and daily fecundity to those when alyssum flowers were present. The availability of food had a significant effect on the offspring sex ratio of D. tasmanica. Parasitoids reared from naturally-occurring leafrollers produced an equal sex ratio, assumed to be the evolutionarily stable strategy (ESS) for this species. In the laboratory, this ESS was observed only when parasitoids had access to alyssum flowers. Without food, or with honeydew only, sex ratios were strongly male-biased. In the field, floral resources affected the sex ratio of D. tasmanica only when this species was reared from leafrollers released and recovered in Marlborough. In that experiment, buckwheat shifted the sex ratio in favour of female production from the equal sex ratio found in control plots. No firm explanations can be given to account for these results, due to a lack of research in this area. Possible mechanisms for the changes in sex ratio with flowers are discussed. This study demonstrated that flowers are an important source of nutrients for D. tasmanica, influencing the longevity, fecundity and offspring sex ratio of this species. However, only some of the field experiments were able to show any positive effect of the provision of floral resources on parasitoid abundance or parasitism rate. More information is needed on the role these parasitoids, and other natural enemies, play in regulating leafroller populations in New Zealand vineyards, and on how they use floral resources in the field, before recommendations can be made regarding the adoption of this technology by growers.

Summaries in German and English / Text in German / Ziel der Forschungsarbeitet ist es, zu zeigen, dass die johanneische Weinstockrede das alttestamentlich und frühjüdisch geprägte Weinstockmotiv aufgreift und weiter entfaltet. So finden sich in Joh 15:1-8 die Beziehungsebene zwischen Gott und seinen Nachfolgern, die ethische Konnotation, der Gerichtsgedanke, der messianisch-eschatologische Aspekt und der Gedanke von Fruchtbarkeit und Fülle wieder. Es wird deutlich, dass sich in Jesus erfüllt hat, worauf die alttestamentlichen und frühjüdischen Schriften durch die Verwendung des Weinstockmotivs abgezielt haben: Er ist der angekündigte Messias, dessen Kommen Fülle mit sich bringt. Dies hat sich bereits durch Jesu erstes Zeichen, die Verwandlung von Wasser zu Wein (Joh 2:1-11), angedeutet. Neu ist der Gedanke, dass Jesus seine Nachfolger in sein Wirken mit einbezieht. Sie partizipieren an seiner messianischen Fülle und produzieren den Überfluss in Abhängigkeit von Jesus auch selbst mit. Voraussetzung dafür ist, dass die Jünger ihre enge Beziehung zu Jesus durch Gebet und das Einhalten seines Wortes aufrechterhalten und sich an seinem Vorbild orientieren. / The purpose of this thesis is to show that the Johannine vine speech takes up and further develops the vine motif of the Old Testament and early Jewish history. In John 15:1-8 we find emphasis on the relationship between God and his disciples, the ethical connotation, the warning of judgement, the messianic-eschatological aspect and the concepts of fruitfulness and fullness. I will show in this thesis, that the the Old Testament and early Jewish writings that use the vine motif are fulfilled in Jesus Christ: He is the announced Messiah, whose coming will bring fullness. This is already implied in Jesus’s first miracle, turning water into wine (John 2:1-11). What is new is that Jesus includes his disciples in his ministry. They participate in his messianic abundance and in dependence on Jesus they themselves produce abundance. The prerequisite for this abundant fruitfulness is a close relationship with Jesus through prayer, abiding in his word, and following his example. / New Testament / M. Th. (New Testament)
