“…Salvo et al (2012) developed regression models as a function of climatic variables for estimating the yield of blueberries in Chile. Pedro Junior et al (2014) produced estimation models for soluble solids and titratable acidity of grapes for the state of São Paulo, also using regressions, as a function of growing degree days. Similarly, Nyamdorj et al (2014) developed empirical models to estimate the responses of yield and quality of blueberries in eastern Australia as a function of climatic variables.…”

Forecasting is the act of predicting unknown future events using available data. Estimating, in contrast, uses data to simulate an actual condition. Brazil is the world's largest producer of oranges, and the state of São Paulo is the largest producer in Brazil. The BValência^orange is among the most common cultivars in the state. We analyzed the influence of monthly meteorological variables during the growth cycle of Valência oranges grafted onto BRangpur^lime rootstocks (VACR) for São Paulo, and developed monthly agrometeorological models for forecasting the qualitative attributes of VACR in mature orchard. For fruits per box for all months, the best accuracy was of 0.84 % and the minimum forecast range of 4 months. For the relation between°brix and juice acidity (RATIO) the best accuracy was of 0.69 % and the minimum forecast range of 5 months. Minimum, mean and maximum air temperatures, and relative evapotranspiration were the most important variables in the models.

“…Another potential hybrid cultivar for grape juice production is IAC 138-22 Máximo ('Seibel 11342' × 'Syrah'), which was developed by the genetic improvement program of Instituto Agronômico (IAC) (Souza & Martins, 2002). Besides being used in winemaking, it has been recommended for juice production due to its high yield associated with a high amount of phenolic compounds and a high antioxidant activity in grape berries (Santos et al, 2011;Pedro Júnior et al, 2014;Silva et al, 2019).…”

The objective of this work was to evaluate the productive performance and physicochemical characteristics of the Isabel Precoce, BRS Carmem, BRS Cora, and IAC 138-22 Máximo grape (Vitis labrusca) cultivars for juice grafted onto the 'IAC 572 Jales' and 'IAC 766 Campinas' rootstocks. A randomized complete block design, in a 4×2 factorial arrangement, was used. Productive performance was evaluated through: production per plant; yield; number of clusters per vine; and physical characteristics of clusters, berries, and rachis. The physicochemical characteristics of must composition were also determined through the content of soluble solids, reducing sugars, titratable acidity, maturity index, and pH. Since there was no significant interaction between cultivars and rootstocks for most of the evaluated characteristics, each factor was analyzed separately. The 'IAC 766 Campinas' rootstock provided a higher yield and more suitable physicochemical characteristics for the four cultivars. However, regardless of the rootstock used, cultivars BRS Carmem, IAC 138-22 Máximo, and Isabel Precoce were more productive than BRS Cora.

A B S T R A C TThe objective of this work was to evaluate the yield components and physicochemical characteristics of bunches and berries of new grape varieties for juice elaboration, which were 'Isabel Precoce' (Vitis labrusca L.) and the hybrids 'BRS Carmem', 'BRS Cora' and IAC 138-22 'Máximo' grown onto 'IAC 572' and 'IAC 766' rootstocks under tropical conditions. The yield components (number of bunches and yield per vine, as well as productivity) and the physicochemical characteristics of the bunches and berries of the eight scion-rootstock combinations were evaluated in three seasons. All data were subjected to analysis of variance and principal components analysis. The varieties 'Isabel Precoce', 'BRS Cora' and IAC 138 22 'Máximo' produced high fruit yield, with the number of bunches and yield per vine similar to one another and superior to those of 'BRS Carmem'. Significant differences occurred among varieties in the physicochemical grape characteristics. 'Isabel Precoce' and 'BRS Carmem' grapes had balanced levels of sugar and acid content, and 'BRS Cora' presented large bunches and berries, reaching high soluble solids content despite the high acidity. IAC 138-22 'Máximo' grape also had large bunches but small berries and limited potential in the accumulation of sugars. The 'IAC 766' rootstock resulted in the best performance across all four varieties evaluated, showing maximum results in terms of fruit yield and physicochemical quality attributes of grapes.
