“…No entanto, inúmeros fatores podem interferir no teor de nutriente exibido na análise foliar, destacando-se, principalmente, a combinação da variedade copa e de porta-enxerto. Trabalhos na literatura relataram a variação nos teores de nutrientes em função do porta-enxerto (ALBUQUERQUE; DECHEN, 2000;TECCHIO et al, 2007;CSIKÁSZ-KRIZSICS;DIÓFÁSI;MIELE et al, 2009). Tecchio et al (2007), em levantamento nutricional da videira 'Niagara Rosada', constataram que, com o porta-enxerto 'IAC 766', os teores foliares de N e K na 'Niagara Rosada' foram maiores quando comparado com o porta-enxerto 'Ripária do Traviú'.…”

RESUMO-Realizou-se um levantamento nutricional em 93 vinhedos nas regiões vitícolas de Jundiaí, São Miguel Arcanjo e Jales, no Estado de São Paulo, tendo por objetivo comparar os teores de nutrientes em amostras foliares, o teor de nitrato e de potássio na seiva do pecíolo e o índice relativo de clorofila (IRC) da videira 'Niagara Rosada'. Em 20 plantas selecionadas de cada vinhedo, amostraram-se folha inteira, limbo e pecíolo no pleno florescimento da videira. Posteriormente, realizou-se a medição do IRC no limbo e dos teores de NO 3 -e de K + na seiva dos pecíolos. Nas amostras foliares, foram determinados os teores de macro e micronutrientes. Os vinhedos amostrados foram agrupados em função da região de estudo, sendo que cada vinhedo representou uma repetição, totalizando 45; 24 e 24 repetições, respectivamente, nas regiões de Jundiaí, São Miguel Arcanjo e Jales. Nos vinhedos selecionados da região de Jales, as plantas apresentaram maiores teores foliares de P, K, Ca, Mg, S, Fe e Mn, além de maiores IRC e teores de nitrato e potássio no pecíolo. Estas variações nos teores foliares foram relacionadas aos porta-enxertos utilizados nas regiões de estudo, sendo o 'IAC 766', 'IAC 572' e 'Ripária do Traviú', respectivamente, nas regiões de Jundiaí, Jales e São Miguel Arcanjo. Evidenciou-se a necessidade de se adequarem as faixas de concentração de nutrientes nas análises foliares, mediante ensaios regionais, levando em consideração o porta-enxerto e a região em estudo. Termos para indexação: Vitis, análise foliar, nutrição mineral, videira. NUTRIENTS LEVELS, RELATIVE CHLOROPHYLL INDEX AND CONCENTRATION OF NITRATE AND POTASSIUM IN THE PETIOLE OF 'NIAGARA ROSADA' GRAPEVINEABSTRACT-A nutritional survey was carried out in 93 vineyards of the wine regions of Jundiaí, São Miguel Arcanjo and Jales (state of São Paulo-Brazil), aiming to compare the nutrient concentration in leaf samples, the concentration of nitrate and potassium in the petiole sap and the relative chlorophyll index (IRC) of 'Niagara Rosada' vineyard. Leaves, blade and petiole in full bloom vines were sampled in 20 plants selected from each vineyard, and evaluations of the IRC in the leaf blade and the levels of NO3-and K in the petioles sap were realized. Macro and micronutrients concentrations were measured in leaf samples. The sampled vineyards were grouped by region of study, and each vineyard was considered as a replicate sample, totaling 45, 24 and 24 repetitions, in Jundiai, São Miguel Arcanjo and Jales, respectively. Sampled vineyards from the Jales region showed higher leaf concentrations of P, K, Ca, Mg, S, Fe and Mn, and also higher IRC and levels of nitrate and potassium in the petiole. These differences were related to the different rootstocks used, which were 'IAC 766', 'IAC 572' and 'Riparia of Traviú', respectively, for Jundiaí, Jales and São Miguel Arcanjo. The differences highlight the need to adjust the concentration ranges of nutrients in leaf analysis, through regional trials, taking into account the rootstock and the region under study.

“…Similarly, Albuquerque and Dechen (2000) also reported that biomass production was directly related to the amount of nutrient accumulation (N, P, K and Ca), and grapevines grafted on 'VR 043-43' presented the highest accumulation of dry matter in all plant parts.…”

This study evaluated the immobilization and nutrient uptake in an experimental organic vineyard of 'Early Isabella' grapevines in the Midwestern region of Parana State, Brazil. The experimental design was implemented in randomized blocks with two different rootstocks 'Paulsen 1103' and 'VR 043-43' along with four replications and three plants per plot. Five years after planting, one plant per plot was completely removed from the soil and then subdivided into root, stem and canes. The remaining plants in the area were managed until harvest. The sectioned parts and clusters were dried in a forced air oven at 65°C. The dry mass was subsequently determined and mineral analyses were performed. The amounts of nutrient uptake immobilized by 'Early Isabella' grapevines with yields between 9.9 and 16.6 t ha -1 were 64.9, 19.0, 156.9, 45.8 and 12.7 kg ha -1 for N, P, K, Ca, Mg, respectively, when grafted on Paulsen '1103 ' and 112.8, 29.3, 260.8, 82.3 ResumoO objetivo do trabalho foi avaliar a imobilização e extração de macronutrientes em um vinhedo experimental de cultivo orgânico de videiras cv. Isabel Precoce na região Centro-Oeste do Paraná. O delineamento experimental foi em blocos casualizados, com dois tratamentos (porta-enxertos: Paulsen '1103' e 'VR 043-43'), quatro repetições e três plantas por parcela. Cinco anos após o plantio, uma planta por parcela foi totalmente removida do solo, sendo que posteriormente as videiras foram subdivididas em três partes: raiz, caule e ramos do ano. A partir das plantas remanescentes no campo, realizou-se a colheita dos cachos. Para as avaliações, as plantas e os cachos foram secos em estufa de ar forçado a 65°C. Posteriormente, determinou-se a massa seca e se realizaram análises do teor dos macronutrientes dos tecidos vegetais Pelos resultados obtidos, verificou-se que as quantidades de nutrientes imobilizadas e exportadas pela videira cv. Isabel Precoce com produtividade entre 9,9 e 16,6 t ha -1 , em função do porta-enxerto foram para N, P, K, Ca, Mg, respectivamente de 64,9; 19,0; 156,9; 45,8

“…There was an isolated effect of rootstocks and yield cycles on nutrient content in 'Venus' grape vines branches and clusters, except for P, Fe and Zn contents in branch's samples (Tables 2 and 3). Nevertheless, differences in nutrient content of grape vine branches and clusters could be found to the genetics of rootstock and their vigor; such changes have been reported by several authors (Albuquerque and Dechen, 2000;Tecchio et al, 2007;Miele et al 2009;Tecchio et al, 2011). In branches of 'Venus' grape vines grafted onto different rootstocks during two growing seasons, results indicated an average of 9.9 g kg -1 N, 1.6 g kg -1 P, 6.6 g kg -1 K, 10.4 g kg -1 Ca, 2.3 g kg -1 Mg and 1.0 g kg -1 S. Furthermore, same sample presented the averages of 15.9 mg kg -1 B, 30.4 mg kg -1 Cu, 62.4 mg kg -1 Fe, 410.2 mg kg -1 Mn and 72.14 mg kg -1 Zn.…”

The current study aimed to assess the influence of the 'IAC 766', 'IAC 572',' rootstocks on nutrient uptake of 'Venus' grape vine by pruning branches and harvesting clusters during two consecutive grape growing seasons. The experiment was conducted in Votuporanga, state of Sao Paulo. Treatments consisted of the variety 'Venus' grafted onto four rootstocks during two growing seasons (2013 and 2014). The rootstocks evaluated were 'IAC 766', 'IAC 572', 'IAC 313' and 'IAC 571-6'. We sampled the grape branches at pruning and their clusters at harvest time. The macro and micronutrient contents in both branches and clusters were analyzed. Nutrient uptake and removal were separately estimated in pruned branches and harvested clusters by uptake nutrient sum. Results indicated great nutrient uptake means in 'IAC 572' and 'IAC 766' during both seasons. Moreover, total removal uptake showed the following order K > N > Ca > P > Mg > S > Mn > Fe > Zn > B > Cu in pruned branches and harvested clusters.
