Characterization of the Wine Grape Thermohydrological Conditions in the Tropical Brazilian Growing Region: Long-Term and Future Assessments Repositório Alice
TEIXEIRA, A. H. de C.; TONIETTO, J.; PEREIRA, G. E.; HERNANDEZ, F. B. T..
Over the last years, Brazil has appeared among the newtropicalwine producing countries.Thejoined effect of rising air temperature and decreasing precipitation makes it important to quantify the trend of the thermohydrological conditions of the commercial vineyards. The aims of the current research were to classify and delimit these conditions for the winemaking processes under different time scenarios in the BrazilianNortheastern region. Bioclimatic indicatorswere used togetherwith long-termweather data and projections of the IPCC emission scenarios under simulated pruning dates.The results showed that decreasing of precipitation should be good for wine production when irrigation water is available, but rising air temperature will affect the wine quality...

NACHTIGALL, G.R.; NOGUEIROL, R.C.; ALLEONI, L.R.F..
O trabalho teve como objetivo avaliar a distribuição de formas de cobre, em função do pH e da adição de cama-de-frango, em amostras da camada superficial (0 a 10 cm) de um Neossolo Litólico distrófico típico e de um Cambissolo Húmico alumínico típico, da região da Serra Gaúcha, cultivados por mais de 15 anos com parreirais que receberam aplicações sucessivas de produtos fitossanitários à base de cobre. Para avaliar os efeitos da variação do pH e do teor de matéria orgânica do solo nas formas de cobre, cinco doses de HNO3 (50, 100, 200, 300 e 400 mmol kg-1) e quatro doses de cama-de-frango em base seca (10, 20, 40 e 80 t ha-1) foram adicionadas aos solos. As frações observadas foram: trocável; ligada à matéria orgânica; ligada a óxidos de Fe, de Al e de Mn;...

VIEL, J. A.; ROSA, K. K. da; HOFF, R.; MOURA, N. S. V..
The objective of this study was to investigate the land use and land cover patterns in the region Vale dos Vinhedos designation of origin and to relate them to the geomorphological mapping aiming to contribute to the implementation, monitoring and management of the areas intended to Geographical Indications for winesandsparkling wines. For this purpose, the geomorphology and the classes of land cover and land use were mapped. Both mappings were carried out usinggeotechnologiestechniques. The shape pattern similar to high Hills is the most representative in the study area, occupying 77.13%. In the mapping of land use and land cover, the most representative class is forests (native or not), occupying 36% of the study area. The intersection between of the...

Geotechnologies and soil mapping for delimitation of management zones as an approach to precision viticulture. Repositório Alice
FILIPPINI ALBA, J. M.; FLORES, C. A.; MIELE, A..
Data of the physical and chemical properties of soils from three vineyards located in Vale dos Vinhedos, Bento Gonc ̧alves, Rio Grande do Sul state, in southern Brazil, were processed. Soil mapping was performed by means of four profiles and the digital elevation model in detailed scale. Then, superficial soils (0?20 cm) were sampled according to a grid pattern. Analysis of variance (ANOVA), kriging, and unsupervised classification methods were applied on physical and chemical data of superficial soils sampled according to grid pattern. This study aimed to compare both methods, the conventional soil mapping and the map produced with superficial soil sampling, about their potential for definition of the management zones, as an approach for...

Measurements and modelling of evapotranspiration to assess agricultural water productivity in basins with changing land use patterns: a case study in the Sao Francisco River basin, Brazil. Repositório Alice
TEIXEIRA, A. H. de C..
The São Francisco River basin in Brazil is marked by socio-economic disparities and environrnental vulnerabilities. Water managers in the semi-arid region of the basin are faced with several challenges, such as competition among different water user groups, local over-exploitation of aquifers, c1imateand land use changes, non-source pollution, erosion, and sedimentation. Water policy makers have to work out strategies for integrated water management, which rely on a proper knowledge base of the physical conditions encountered in the basin. The intensification of horticulture in the semi-arid north-eastem region of Brazil replaces natural vegetation (i.e. caatinga) by irrigated fruit crops. A proper knowledge of the water balance from these different...

Resistance assessment of grapevine rootstocks used in Chile to the root-knot nematodes Meloidogyne ethiopica, M. hapla, and M. javanica Ciencia e Investigación Agraria
Aballay,Erwin; Vilches,Oscar.
The rootstocks 1103 P, 101-14, K 5BB, SO4, and 3309 were assessed to determine their resistance to the three common Meloidogyne species present in Chilean vineyards, M. ethiopica, the most frequent species, M. hapla and M. javanica. Their response was compared to three ungrafted cultivars, Thompson Seedless, Pinot Noir and Chardonnay. To perform this study, two month-old plants produced from cuttings were inoculated with 5,000 eggs per 3-L pots, filled with steamed substrate and kept in a glasshouse covered with a black mesh to intercept 30% of sun light and avoid heating of the substrates. After a growth period of six months, plants were removed from the pots, and resistance was determined by measuring root weights, the number of galls and eggs per g of...

Rootstock-scion interaction: 2.effect on the composition of cabernet sauvignon grape must. Repositório Alice
MIELE, A.; RIZZON, L. A..
ABSTRACT - The interaction between rootstock, scion and the environment may induce different responses to the grapevine physiology and, consequently, to the grape composition. The vineyards of Serra Gaúcha, Brazil, are established in different soil types, each with different morphological and physicochemical attributes. Moreover, the grapevines are grafted onto a diversity of rootstocks. Therefore, this study aimed to determine the effect of 15 rootstocks in the composition of the Cabernet Sauvignon (CS) grape must. The following rootstocks were used: Rupestris du Lot, 101-14 Mgt., 3309 C, 420A Mgt., 5BB K, 161-49 C, SO4, Solferino, 1103 P, 99 R, 110 R, Gravesac, Fercal, Dogridge and Isabel, featuring some genetic diversity altogether. The experimental...

Sensitivity of grapevine rootstocks to changes in zinc concentration in the soil. Repositório Alice
MELO, G. W. B. de; SILVA, L. S. da; BRUNETTO, G.; ZALAMENA, J.; ALBARELLO, J. B..
Abstract The objective of this study was to evaluate the effect of high levels of Zn in soil on productivity and nutritional and root performance of young grapevine rootstocks, as well as to identify variables that are affected by excess Zn. Five rootstocks (SO4, Paulsen 1103, IAC572, IAC313 and 420A) were grown in pots containing soil with the addition of 0, 20, 40, 80 or 160 mg kg-1 of Zn. The rootstocks were pruned at 45 days, discarding the shoot. After re-sprouting, a main branch was maintained and evaluated after 50 days in terms of height, number of leaves, and leaf area; dry matter, concentration and accumulation of Zn in the shoots and roots; and area, olume, length and diameter of the root system. The variables of plant height, leaf area, and dry...
