Abstract. The objective of this experiment was to evaluate the effect of garlic extract, H 2 O 2 and hydrogen cyanamide on dormancy break, budding and maturation of ''Cabernet Sauvignon'' in the Campaign Region -Brazil. In late winter 2014 and after drought pruning were performed spraying in the bud: T1 -distilled water (control); T2 -3.0% of hydrogen cyanamide; T3 -18.0% H 2 O 2 ; and T4 -3.0% garlic extract. It was evaluated in the field: the number of sprouted buds per plant, number of bunches per plant and weight of bunches per plant; and laboratory: on ripening, performed weekly from the color change of 360 berries per treatment for analyzes solids soluble -SS (Brix) pH and titratable acidity -TA (% tartaric acid). It was observed that the vines of treatment T4 (3.0% garlic extract), showed higher percentage of buds sprouting (63 shoots plant -1 ). Already at the number of clusters and weight per plant, there were no statistical differences between all treatments. The results obtained in the laboratory to SS, pH and TA did not differ statistically for the four tested treatments.

The objective of this study was to evaluate the effect on must from defoliation in 'Pinotage' in a property in the region Dom Pedrito, conducted in espalier and from East / West direction. The work was performed by the Nucleus of Study, Research and Extension in Oenology (NEPE 2 ); in 2014/2015 and 2015/2016 harvests. The treatments were: T1 -control; T2 -Defoliation in thenorth; T3 -Defoliation in the south and; T4 -Defoliation South and North. The response variables were analyzed by infrared spectrometry fourier transform (FTIR); these analyzes in the must were: total soluble solids (TSS) in • Brix, pH, potassium and gluconic acid. The experimental design was a randomized block design with four replications and 20 plants per plot. The results were submitted to analysis of variance (F test) and multiple comparison of averages by Tukey test at 5% probability. TSS is kept equal in the 2014/15 crop, but in the 2015/16 season were different and the treatment T4 (Defoliation North and South); significantly higher, followed by treatment T3 (Defoliation to the south).
