Épocas de desponte de cachos na variedade de uva rainha Itália (Vitis vinifera L.), produzida em ambiente protegido na Serra Gaúcha
The objective of the work was to evaluate the production and quality of the cultivar Italia produced in a protected environment, submitted to three seasons of topping of bunch. The experiment was carried out in 2015, in Caxias do Sul - RS. The experimental design used blocks at random with four treatments, being: without topping of bunch, topping of bunch in pre-flowering, topping of bunch in full bloom, topping of bunch in post-blooming. The variables analyzed were: production per plant, bunch weight, bunch length, berry diameter and number of bunches soluble solids and titratable acidity. Regardless of the pruning time of the bunches, the factors of production and the evaluated chemical physics were not affected, obtaining bunches with weight and shape according to market requirements.
