In southern Brazil there is a predominance of labrusca and hybrid varieties for wine and juice production due to climatic conditions of high rainfall, temperature and relative humidity. Growing varieties that combine disease resistance and wine quality (PIWI) can be an alternative to improve wine quality. The objective of this work was to evaluate the performance of three PIWI varieties (Felicia, Calardis Blanc and Aromera) in two regions (Videira, 27∘01′S and 51∘08′W, altitude 830 m; and São Joaquim, 28∘13′S and 50∘04′W, altitude 1100 m) in the vintage 2018. The date of occurrence of main phenological stages, productiveindexes, clusters characteristics and grape qualitative indexes was evaluated. There was no difference for budbreak date, but flowering, veraison an maturity time varied between regions. The development of plants is slower when they are cultivated at a higher altitude. The number of clusters per plant and yield were higher at 830 m for all varieties. For productive indexes Felicia and Calardis Blanc varieties stood out in relation to Aromera in all parameters. Among the evaluated varieties, Felicia and Calardis Blanc were better adapted to the lower altitude region and had higher productivity and the same grape quality. On the other hand, Aromera presented higher productivity at 830 m but higher soluble solids content at 1100 m.

Loire Valley

<p style="text-align: justify;">In the framework of a research programme on the “ terroirs ” in viticulture, a red of experimental plots was established in the Loire Valley area in 1978 with the Cabernet Franc variety. In 1988, eleven of those plots were given an intensive follow-up, with special emphasis on the phenological stages, the growth and development of the vegetative apparatus and the composition of the grapes at harvest time. After a few years, we can consider that 1988 was an average year for the last fifteen vintages, both on the climatic side and on the wine quality side. Therefore it seems to be justified to use the data of that particular year to study the “ terroir ” effect on the composition of the grapes. The results show important differences between “ terroirs ” in terms of precocity of the phenological stages, stems growth, setting of the leaf area, vigour and productivity of the plants. These differences are found also during the maturity process and at harvest time ; sugars, organic acids, anthocyanins and polyphenols are concerned. An index for measuring the precocity of the grapevine cycle on each “ terroir ” is used to compare the “ terroirs ” and to establish relationships with the composition of the grapes at harvest time. Through the analysis of the data, it is possible to distinguish two groups of factors which determine the behaviour of grapevine in a given “ terroir ”. The first one is related to the precocity of the cycle of the plant ; it influences the quality of the grapes at harvest time. The second is related to the vigour ; it is linked to the productivity of the plants.and the acidity of the must. The level of development of the primary leaf area at flowering time seems to play an important role in relation with the composition of the grapes in sugars, organic acids and anthocyanins ; the earlier the flowering, the better the relationship.</p>

Physiological Values

The numerical crop growth model Italian Vineyard Integrated Numerical model for Estimating physiological values (IVINE) was developed in order to evaluate environmental forcing effects on vine growth. The IVINE model simulates vine growth processes with parameterizations, allowing the understanding of plant conditions at a vineyard scale. It requires a set of meteorology data and soil water status as boundary conditions. The primary model outputs are main phenological stages, leaf development, yield, and sugar concentration. The model requires setting some variety information depending on the cultivar: At present, IVINE is optimized for Vitis vinifera L. Nebbiolo, a variety grown mostly in the Piedmont region (northwestern Italy). In order to evaluate the model accuracy, IVINE was validated using experimental observations gathered in Piedmontese vineyards, showing performances similar or slightly better than those of other widely used crop models. The results of a sensitivity analysis performed to highlight the effects of the variations of air temperature and soil water potential input variables on IVINE outputs showed that most phenological stages anticipated with increasing temperatures, while berry sugar content saturated at about 25.5 °Bx. Long-term (60 years, in the period 1950–2009) simulations performed over a Piedmontese subregion showed statistically significant variations of most IVINE output variables, with larger time trend slopes referring to the most recent 30-year period (1980–2009), thus confirming that ongoing climate change started influencing Piedmontese vineyards in 1980.

Deficit irrigation is one of the most researched irrigation water management techniques for vines with many potential benefits for successful grape production. For optimal growth and grape quantity of individual variety, suitable water quantity over growing season should be provided. Due to more frequent droughts vine irrigation will be needed also in Slovenia. The principle of deficit irrigation is affecting vine growth and quality and quantity of the yield by adding smaller amount of water than optimal. Decreased vine growth (reduced growth of shoots, 15.5 % for 'Monastrell, reduced leaf area, reduced pruning mass), smaller berries, and thus yield quantity from 38 % to 57 % for ‘Monastrell’ and 24 % to 27 % for 'Tempranillo', respectively, improved berry composition (higher sugar and antocianin content, lower acid content), better water use efficiency, meaning higher yield per unit of added water, are expected. Most suitable method for deficit irrigation management of vines is by measuring plant water potential. For successful transfer of deficit irrigation in practice, good knowledge of critical growth stages of irrigated vine variety and its behavior in a certain environment is needed. Successful application of this irrigation method in practice will be possible only with financial and expert support.
