Resumo: | The rustic grapes cultivation is recent in Toledo (PR), thought the area and production have increased 67.69% and 62.08% respectively in the last ten years. Thus are necessary researches about these cultivars in the region, seeking an increase in agronomic qualities. The goal of this research was evaluate the production and quality of American native grapes grafted on soil and climatic conditions of Toledo. For this, we used in the experiment three American cultivars (rustics) vine (Bordô, Isabel Precoce and Niagara Rosada) grafted on two rootstocks (IAC-Campinas 766 and 420-A). The experiment began in 2010, in particular property located in St. Valentin Line, Toledo (PR). Was employed as spacing 2.00 m between rows and 1.25 m between plants. The harvests 2011/12, 2012/13, 2013/14 and 2014/15 were evaluated the number of bunches per plants average size of fruits (cm), production per plant (kg) and soluble solids (° Brix). The experimental design was in randomizes blocks in factorial 3x3x4 scheme (form of propagation x cultivars x crop) containing 4 replications and 8 plants per treatment. In the average size of fruits (cm) the cultivar Bordô was higher in 2014/2015. Another important factor is that the rootstocks were higher than the ungrafted. The Isabel Precoce and Niagara Rosada when grafted did not differ to ungrafted. When compared the harvests, pé-Franco only equaled the grafted cultivars in crop 2014/2015. The number of fruits per plant did not differ statistically. Rootstocks did not influence the cultivars for the parameter production plants (kg plant-1). For soluble solids (Brix) in the cultivar Bordô with IAC-766 rootstock was superior to 420-A, but doesn‟t differed from ungrafted. The grafted Isabel Precoce were similar to ungrafted. However for ungrafted Niagara Rosada and grafted with IAC-766 rootstock were higher than grafted with 420-A rootstock. Both rootstocks as pé-franco are possible to use at conditions in the Toledo region (PR) |
