“…The evaluation of plant vigor, measured by weight of material removed in the winter pruning, was made only in two seasons but the results were quite consistent. The high vigor of the canopy induced by IAC series rootstocks, particularly by IAC 572, had already been observed in other studies [11]. In the present experiment, for the IAC 572 plots, it was necessary three green pruning interventions to control vegetative growth.…”

Abstract. Young vine decline, caused by the ground pearl or margarodes (Eurhizococcus brasiliensis) and pathogenic fungi (Cylindrocarpon, Phaeoacremonium and others), is a major problem in many vineyards of Southern Brazil. According to previous studies, the most resistant roostocks were hybrids of tropical species, such as Vitis caribaea (IAC 572, IAC 571-6, IAC 766) and V. cinerea (IAC 313). A medium resistance level was observed in V. champinii (Dog Ridge) and Muscadinia rotundifolia hybrids (VR 043-43). However, these rootstocks have not being used in grape growing areas of Southern Brazil. An experiment was carried out to evaluate the agronomic characteristics of the scion cultivar Moscato Embrapa grafted on these rootstocks compared to Paulsen 1103 and R99, considered standards for this region. The tropical rootstocks IAC 313, IAC571-6, and IAC 766 induced earlier bud break compared to Paulsen 1103, the opposite of VR043-43 and Dog Ridge. In general aspects, all rootstocks tested can be used for grape production. Even the tropical rootstocks with no winter dormancy behave as normal rootstocks when grafted. IAC 572 has an advantage of not inducing early bud break. However, excessive vigor is the most limiting factor for IAC 572, requiring especial management practices to control vegetative development.

“…In colder regions, as in the Midwest of Santa Catarina State, tropical characteristics are limiting factors to its use, such as damage by frost in young plants and induction of early bud break. They also tend to induce excessive vigour to the scion [11].…”

“…Grafting serves as a standard research tool to examine long-distance transport of molecules (Ayre & Turgeon, 2004;Chen, Komives, & Schroeder, 2006;Zhang et al, 2018). In Vitis species, grafting can improve scion productivity and quality and reduce susceptibility (Csikászkrizsics & Diófási, 2012;Dalbó, Schuck, & Basso, 2011;Ollat et al, 2016). To quantify the dynamic distribution of stilbenes in various tissues and organs, we performed a cross-grafting experiment on the four different scion/rootstock combinations ( Figure 3a).…”

Accumulation of stilbene phytoalexins stimulates resistance mechanisms against the grapevine fungus Uncinula necator. However, the defensive mechanisms triggered by stilbene synthase (STS) genes, remain largely unknown. Here, we report the function and molecular mechanism of the stilbene synthase gene VpSTS29/STS2 from Vitis pseudoreticulata in the regulation of plant responses to powdery mildew. Stilbene synthesis occurred mainly in root tips and mesophyll cells of transgenic grapevines via transport through the vascular bundles. Overexpression of VpSTS29/STS2 in Vitis vinifera increased the abundance of STSs in mesophyll tissue and resulted in the accumulation of biologically active resveratrol derivatives at the invasion site. Similarly, expression of VpSTS29/STS2 in Arabidopsis increased resistance to Golovinomyces cichoracearum. The VpSTS29/STS2‐expressing Arabidopsis lines showed increased piceid accumulation together with more local hypersensitive reactions, inhibition of mycelial growth, and a reduced incidence of pathogens. Transcriptome profiling analyses demonstrated that VpSTS29/STS2‐induced defences led to reprograming of global gene expression and activation of salicylic acid (SA) signalling, thus increasing expression of WRKY‐MYB transcription factors and other defence response genes. We propose a model for resveratrol‐mediated coordination of defence responses in which SA participates in a positive feedback loop.

“…Já para os demais nutrientes, os porta-enxertos SO4 e IAC 766 obtiveram resultados semelhantes, não diferindo estatisticamente. Essa diferença no acúmulo de nutrientes K e Mg já foi observada por Dalbó et al (2011) ao avaliarem a cv. 'Isabel' sobre os mesmos porta-enxertos ou em pé-franco, verificaram que esse maior acúmulo de Mg geralmente vem acompanhado de menor acúmulo de K, resultando em baixa relação K/Mg.…”

“…Verificou-se que este desequilíbrio era observado principalmente em vinhedos da cultivar Isabel não enxertada (pé-franco), o que levou à hipótese de que o problema teria origem genética. Dalbó et al (2011) verificaram que o equilíbrio K/Mg na cv. Isabel não foi alterado pelo nível de calagem, mas foi altamente influenciado pelo porta-enxerto utilizado.…”

RESUMO Videiras ‘Isabel’ enxertadas em porta-enxerto ‘SO4’ e ‘IAC 766’, e em pé-franco plantadas sobre Nitossolo foram tratadas anualmente com doses crescentes de K2O, a 0; 60; 120 e 180 kg ha-1, durante 5 safras vitícolas (2007/2008; 2008/2009; 2009/2010; 2010/2011; 2011/2012). O delineamento experimental foi em faixas, com cinco repetições, sendo seis plantas por repetição, e os tratamentos, dispostos em esquema fatorial 4x3, com 12 tratamentos, correspondentes às quatro doses de adubação potássica e aos três portaenxertos. No estádio de mudança de cor da casca das bagas, coletaram-se pecíolos para determinar o teor de nutrientes no tecido foliar das uvas. Na ocasião da colheita, foram avaliados comportamentos vegetativos e produtivos, como produtividade, peso de poda, índice de Ravaz e características químicas da polpa das bagas, como sólidos solúveis totais, acidez total titulável e pH. O aumento da adubação potássica não representa ganho na produtividade na cv. Isabel nem no acúmulo de sólidos solúveis totais nas uvas. K e Mg nos pecíolos de uvas são influenciados pela forma de cultivo (enxertada ou pé-franco). Videiras ‘Isabel’ cultivadas em pé-franco têm menor capacidade de acúmulo de K e maior acúmulo de Mg nos pecíolos. Nas condições do solo em que foi desenvolvido o trabalho, não se justifica a adubação potássica do vinhedo.
