“…Analyzing CL, CFM and VB, it was observed that the plants grafted on the 'Harmony' rootstock had higher average values, being superior to the other rootstocks. This fact can be justified by the fact that this rootstock shows less vigor to the canopy (LEÃO et al, 2011), favoring better assimilation and distribution of nitrogen. Thus, the content of this nutrient in the leaves has great influence in the expression of genes for the synthesis of carboxylic enzymes (ribulose 1,5-bisphosphate carboxylase, Rubisco and phosphoenol-pyruvate carboxylase, PEPcase).…”

“…Leão et al (2011), in a study with cv. Sugraone on four rootstocks observed that 'Harmony', 'SO4' and 'Paulsen 1103' did dot differ statistically and were superior to '420-A', confirming the higher berry diameter expressed by 'Harmony' and 'Paulsen 1103' rootstocks.…”

“…Rootstocks with a moderate vigor tend to have a better source/drain ratio, facilitating the translocation of photoassimilates and nutrients, such as potassium to the fruit. Leão et al (2011) observed that the use of the rootstock 'Paulsen 1103' led to a higher amount of soluble solids in berries of the 'Superior Seedless' vine.…”

ABSTRACT-Methods of nitrogen analysis were adopted in leaf tissues in the laboratory, nitrate content in the sap of petioles and chlorophyll relative index (CRI, in SPAD unit), as well as the evaluation of the buds fertility rates, production and qualitative aspects of cluster and berries of 'Thompson Seedless' vine, grafted on rootstocks 'Harmony', 'Jales' 'Paulsen 1103' and 'SO4'. The applied dose of N was 80 kg ha -1 , and the experiment was installed in the Submédio do Vale do São Francisco, Brazil. The experiment was performed in a randomized blocks design, with four treatments and five replicates, with the experimental plot represented by five plants. In addition to the analysis of N, cluster length and width (cm) and fresh mass (g), berries length, diameter (mm), volume (mL), mass of fresh matter of berries, soluble solids (SS), titratable acidity (TA), SS/TA ratio, potential bud fertility (productive, vegetative, dead and dark buds in %) and real bud fertility (%). There were differences in nitrogen content in the leaves, nitrate in sap and CRI of 'Thompson Seedless' in relation to rootstocks. 'Thompson Seedless' expressed better potential for the development of clusters and berries when grafted on 'Harmony'. Index terms: Vitis vinifera (L.); plant nutrition; buds fertility; viticultura tropical irrigada AVALIAÇÃO DE NITROGÊNIO, FERTILIDADE DE GEMAS E PRODUÇÃO DA VIDEIRA 'THOMPSON SEEDLESS' SOBRE DIFERENTES PORTA-ENXERTOSRESUMO -Adotaram-se métodos de análise de N em tecidos de folhas em laboratório, teores de nitrato na seiva de pecíolos e o índice relativo de clorofila (IRC, em unidade SPAD), bem como foram avaliados as taxas de fertilidade de gemas, os aspectos produtivos e qualitativos de cachos e bagas da videira 'Thompson Seedless', enxertada sobre os porta-enxertos 'Harmony', 'Jales' 'Paulsen 1103' e 'SO4'. A dose de N aplicada foi de 80 kg ha -1 , e o experimento foi instalado no Submédio do Vale do São Francisco, Brasil. O delineamento experimental utilizado foi blocos ao acaso, com quatro tratamentos e cinco repetições, sendo que a parcela experimental foi constituída por cinco plantas. Além das análises de N pelos métodos citados, avaliaram-se comprimento e largura (cm) e massa fresca de cacho (g), comprimento, diâmetro (mm), volume (mL), massa da matéria fresca de bagas (g), teor de sólidos solúveis (SS), acidez titulável (AT), relação SS/AT, fertilidade de gemas potencial (gemas frutíferas, vegetativas, mortas e escuras, em %) e fertilidade de gemas real (%). Verificaram-se diferenças entre teores de nitrogênio na folha, nitrato na seiva e IRC da 'Thompson Seedless' em relação aos porta-enxertos, e quando enxertada sobre o 'Harmony', a 'Thompson Seedless' expressou melhor potencial para o desenvolvimento de cachos e bagas. Termos para indexação: Vitis vinifera (L.); nutrição de plantas; fertilidade de gemas; viticultura tropical irrigada..1 (Paper 069-16).

“…Leão (2011), analisando a produtividade e qualidade de uvas de mesa sem sementes 'Sugraone' produzidas sobre diferentes portaenxertos no Submédio do Vale São Francisco, observou maior produtividade estimada de 12 t.ha -1 para o porta-enxerto 'Paulsen 1103' em quatro ciclos. Feldberg et al (2007), em Mocambinho-MG, constataram que, na média das cinco safras avaliadas para as videiras 'Crimson Seedless', o porta-enxerto 'Paulsen 1103' induziu ao aumento de 50,6% no número de cachos.…”

As variedades de uvas sem sementes apresentam maior dificuldades de adaptação às condições tropicais do semiárido nordestino, exibindo produções reduzidas e irregulares, resultado de sua baixa fertilidade de gemas, desgrane elevado e suscetibilidade à rachadura de bagas. O objetivo deste trabalho foi avaliar aspectos relacionados à susceptibilidade ao rachamento e podridão de bagas e características agronômicas de uvas sem sementes sob as condições do Submédio do Vale São Francisco. Para isso, o experimento foi conduzido no Campo Experimental de Bebedouro na Embrapa Semiárido, em Petrolina-PE. Foram avaliadas cinco variedades ao longo de dois ciclos de produção, correspondendo aos anos de 2013 e 2014. Utilizaram-se as variedades Adona, BRS Clara, BRS Maria Bonita, Arizul e Thompson Seedless, nas quais foram determinadas as seguintes variáveis: produção (Kg planta-1), número de cachos, massa do cacho (g); teor de sólidos solúveis (oBrix) e acidez titulável (g de ácido tartárico 100mL-1); bagas rachadas (%) e bagas podres (%). Os resultados mostraram que tanto o percentual de rachamento quanto o de podridão apontaram para as variedades BRS Clara e Adona como as mais tolerantes e a variedade Thompson Seedless como a mais suscetível. A maior produção por planta foi obtida no Ciclo 2 para a variedade BRS Clara (20,63 Kg planta-1), seguida da Adona (17,52 Kg planta-1. Assim, as variedades BRS clara e Adona destacaram-se com melhores características de qualidade e maior tolerância à rachadura e podridões de bagas, apresentando potencial para produção de duas safras ao ano no Submédio do Vale São Francisco.

“…The choice of rootstock in viticulture depends on the soil conditions of each producing region and, within a region, it can undergo many variations. This makes it a difficult choice and research papers should be repeatedly done for each specific growing site (Leão et al, 2011).…”

Vineyard cultural practices may influence amount of sugars, acids, phenolic compounds and antioxidant activity of grapes. Thus, the purpose of this study was to evaluate the effect of different shoot topping levels on the chemical characteristics of the grapes during its maturation, yield and the physicochemical characteristics and phenolic compounds of 'Niagara Rosada' grapevine grafted onto different rootstocks. The experiment was conducted in a 2-year-old vineyard of Niagara Rosada cultivar in Southeast of Brazil. The vines were trained on a unilateral cordon system in a vertical shoot positioning. The manual shoot topping was carried by leaving 6, 7, 8 or 9 leaves above the last cluster. Vines were topped 60 days after pruning, when the vines were in the beginning of bunch closure. All vines were grafted onto 'IAC 766' and 'IAC 572' rootstocks. Fruit maturation curve, yield and physicochemical grapes characteristics were analyzed to determine the effects of shoot topping levels and rootstocks. The rootstocks and the different shoot topping levels did not influence the yield, productivity and cycle duration of 'Niagara Rosada' grapevines. Larger and heavier clusters and berries were harvested from vines grafted on 'IAC 766' rootstock. However, grapes harvested from grapevines grafted on 'IAC 572' rootstock presented higher total anthocyanins content. The shoot topping carried out with 7 or 8 leaves above the latest cluster provided higher sugars, total polyphenols content and antioxidant activity.
