Desenvolvimento e ocorrência de pérola-da-terra em videiras rústicas e finas enxertadas sobre os porta-enxertos 'VR 043-43' e 'Paulsen 1103'

Abstract: Este trabalho teve por objetivo avaliar a ocorrência de pérola-da-terra (Eurhizococcus brasiliensis) (Hemiptera: Margarodidae), bem como o desenvolvimento vegetativo e a fenologia das videiras 'Isabel', 'Bordô (Vitis labrusca L.), 'Cabernet Sauvignon', 'Malbec' e 'Merlot' (Vitis vinifera L.) enxertadas sobre os porta-enxertos 'Paulsen 1103' e 'VR 043-43'. O experimento foi conduzido no pomar experimental do Departamento de Agronomia da Universidade Estadual do Centro-Oeste (Unicentro), localizado em Guarapuava… Show more

“…Close results of this study were observed in phenology studies: the cultivate 'Bordô', were reported days average cycle of 159 days in plants with 8 years-old in Caldas, MG, (GONÇALVES et al, 2002) and 132 days in plants with 5 years-old in Guarapuava, PR (BROETTO et al, 2011). The cultivars 'Concord' and 'Bordô', 157 days for the two cultivars, in the South of Minas Gerais (PEREIRA et al, 2008 Means followed by the same lowercase letter in the column and uppercase on the line do not differ significantly by Tukey test at 5% for scion cultivars within the same cycle.…”

“…Phenology varies according to genotype and climatic conditions of each region or from the same region due to seasonal climate throughout the year SENTELHAS, 2003). To understand this variation several authors assess cultivars during consecutive season and use phenological scales to compare and to establish each proper stage to cultivar (GONÇALVES et al, 2002;ANDERSON et al, 2003;MANDELLI et al, 2003;PEREIRA et al, 2008;BROETTO et al, 2011;PRADUBSUK;DAVENPORT, 2011;ANZANELLO et al, 2012). Another method to estimate the duration of the development stages of the vines is the use of thermal index or degree-days (DD).…”

“…In the evaluation of the roots of plants I for the number of ground pearl cysts, an average of 4.2 cysts per plant was reported, a value lower than observed by other authors under field conditions (BOTTON & COLLETA, 2010;BROETTO et al, 2011). Despite the foliar health, the cuttings collected in beds with infestation of ground pearl (I) had, on average, smaller fresh and dry weight, shorter length, and smaller diameter when compared with the cuttings collected from the beds without infestation of ground pearl (Figure 1).…”

“…O Estado do Paraná é o 4º maior produtor do Brasil, e em sua região sudoeste, predomina a atividade em pequenas propriedades, com 44% dos vinhedos constituídos pela cultivar Bordô, e destes, 35% são formados a partir de estacas enraizadas sem uso de porta-enxerto, tratadas também como mudas de pé-franco (ZARTH, 2011). Essa situação representa um entrave que limita a expansão da cultura, uma vez que plantas de pé-franco são em geral menos produtivas (SATISHA et al, 2010), com maior incidência de fungos associados ao declínio e à morte da planta (GARRIDO et al, 2004), além de apresentar maior suscetibilidade à pérola-da-terra (BROETTO et al, 2011).…”
