Maturação e composição das uvas Cabernet Sauvignon e Merlot produzidas na região de São Joaquim, SC

The SR 0.501-17 grape hybrid developed for wine making purposes, is characterized for producing white and small berries with seeds. The purpose of this study was to characterize the phenology, thermal requirements and must physicochemical characteristics of the hybrid, in contrasting climatic conditions due to altitude at Jundiaí (715 m) and Votuporanga (483 m) respectively located at east and northwest of the São Paulo State-Brazil. Evaluations were performed from 2012 to 2016 and observations during the vine growth period and data of phenology and must soluble solids content and acidity measurements at harvest were taken. Average duration of the pruning-harvest period was 146 and 131 days and grape maturation period was 29 and 27 days, respectively for Jundiaí and Votuporanga. Thermal requirement expressed in degree days for the hybrid growth cycle was 1663 and 1923, respectively for Jundiaí and Votuporanga. Rainfall during the maturation period showed negative correlation with total soluble solids and maturation index and positive correlation with titratable acidity. The effect of temperature on vine growth cycle were more pronounced in Jundiaí in comparison to Votuporanga while the effect of rainfall on the maturation characteristics were more effective in Votuporanga when compared to Jundiaí.

Grapevines can be grown in different soil classes and climatic conditions. However, the effect of these variables on grapevine and grape composition is complex. The aim of this study was to evaluate the effect of soil classes and climatic conditions on productive and physico-chemical characteristics and phenolic compounds of Cabernet Sauvignon grapes. The experiment was carried out in São Joaquim (SC), located on the Southern Plateau of Santa Catarina. Cabernet Sauvignon variety was analyzed in three soils (Dystrudepts, Humudepts and Rhodudalfs) and two harvests (2015 and 2016). The climatic variables analyzed were rainfall, insolation and average, maximum and minimum temperatures. Soil physical-chemical attributes, productive and physico-chemical characteristics and phenolic compounds of grapes were analyzed. Both soil class and harvests had significant effect on productive and physico-chemical characteristics and phenolic compounds of grapes. Soil was more important for productive characteristics and phenolic compounds, while meteorological conditions were more important for the physico-chemical characteristics of grapes. Productive characteristics and grape composition were more adequate to wine production in the 2016 harvest and in Rhodudalfs and Dystrudepts soil classes.

This study aimed to evaluate clones of ‘Riesling Itálico’, ‘Chardonnay’, ‘Merlot’ and ‘Cabernet Franc’ grapevines that best adapt to the edaphoclimatic conditions in Veranópolis, RS. The experiment was carried out at the State Center for Diagnosis and Research in Fruticulture - DDPA/SEAPDR. Three 'Riesling Itálico' clones (ISV-1, RI12V23, VCR-365), four 'Chardonnay' clones (INRA-95, INRA-132, INRA-548, VCR-6), four 'Merlot' clones (INRA-181, INRA-347, VCR-13, VCR-494) and seven 'Cabernet Franc' clones (INRA-212, INRA-214, ISV-8, ISV-101, VCR-2, VCR- 4, VCR-10) were evaluated. The experimental design was randomized blocks, with 4 replications and 10 plants per plot. The clones were evaluated in the 2020/2021 cycle for phenology (budburst and maturation dates), production (kg/plant, ton/ha weight/bunch) and fruit quality (soluble solids-SS, titratable acidity-AT, pH). The results showed the potentiality of the clone RI12V23 for 'Riesling Itálico', INRA-132 for 'Chardonnay', VCR-13 for 'Merlot' and VCR-10 for 'Cabernet Franc'. The 'Riesling Itálico' and 'Chardonnay' clones showed greater production precocity than the 'Merlot' and 'Cabernet Franc' clones.
