BIOSTIMULANT AND PHYTOREGULATORS IN THE PRODUCTIVITY AND MATURATION OF CABERNET SAUVIGNON

Biostimulants, Phytoregulators, grape maturation, viti-enological quality.

The cultivation of vine in Brazil has been increasing in recent years, Santa Catarina is one of the main Brazilian states producing grapes, mainly for the elaboration of fine wines. Cabernet Sauvignon was one of the varieties chosen because it has characteristics that made it suitable for the conditions of São Joaquim, such as late sprouting, this characteristic becomes interesting because the late frosts that occur in the region occur after winter, and that could cause damage to budding. The use of phytohormones is one of the tools used in viticulture to improve the quality of grapes. Biostimulants are products or substances that stimulate the natural processes of plants, such as nutrient absorption and tolerance to abiotic stress. In this context, the work will show how the study of the subject can be applied in the area of production and maturation of the Cabernet Sauvignon variety in Serra Catarinense, in order to improve the productivity and quality of phenolic maturation of the mentioned variety and consequently improve the quality of the wines produced in the region, creating a sense of identification between the consumer and the product.
