“…The degree-day concept assumes the existence of a basis temperature, considered 10°C by other authors (Neis et al, 2010;Borges et al, 2014;Barros et al, 2015), below which vegetal growing can be disregarded (Pezzopane et al, 2008). During the 2014 cycle, these minimum temperatures were below the basis temperature for three days.…”

The objective of this work was to evaluate the phenological characteristics and yield of 'Vênus' grapevine (Vitis labrusca) grafted onto different rootstocks, as well the physicochemical traits of its grapes during the 2013, 2014, and 2015 crop seasons. The evaluated rootstocks were 'IAC 766', 'IAC 572', 'IAC 313' and 'IAC 571-6'. The length of the main phenological stages of the grapevine and its thermal demands were assessed during two growing seasons and expressed as days after pruning and degree-day sum, respectively. Grapevine yield and berry physicochemical characteristics were assessed during three crop seasons. 'Vênus' phenological cycle and thermal demands, as well as the chemical characteristics of its grapes, varied with the climate conditions during the crop seasons. Low temperatures increased the grapevine cycle, and higher rainfall indices caused a decrease in the soluble solids of berries, as well as an increase in their titratable acidity. The 'IAC 766' and 'IAC 571-6' rootstocks promote a greater precocity to 'Venus' grapevines, and 'IAC 572' promotes a higher grapevine yield and better physicochemical characteristics of 'Vênus' grapes.

“…Through a literature search, it was found an influence of IAC 766 and IAC 572 on the phenology of several types of grapevines, but the findings differed from each other. Nonetheless, Borges et al (2014) reported that IAC 572 promotes an extension of the phenological cycle of cv. Concord.…”

Rootstock and potassium fertilization, in terms of phenology, thermal demand and chemical evolution, of berries on Niagara Rosada grapevine under subtropical conditions

This study aimed to assess the effect of rootstocks (IAC 572 and IAC 766) and potassium fertilization at different concentrations (0, 75, 150 and 300 kg•ha -1 K 2 O) on the phenology and thermal demand of the Niagara Rosada grapevine, and to evaluate the development of chemical traits during maturation stage. The length of the main phenological stages was recorded within two production seasons.Total thermal demand was calculated using the degree-day concept. The berries' titratable acidity and soluble solids contents were determined during maturation. Results indicated that IAC 572 and IAC 766 rootstocks along with potassium fertilization had no influence on the phenological cycle or thermal demand of the Niagara Rosada grapevine. The production cycle lasted 144 to 148 days with thermal demands ranging from 1,465.2 to 1,615.1 degree-days. For better grape quality, i.e., with a balance between soluble solids and acidity levels, it is estimated that the grape harvest is carried out around 21 to 24 days after the veraison.
