Porta-enxertos e fixadores de enxerto para enxertia hipocotiledonar de maracujazeiro azedo

Abstract

RESUMO Avaliou-se a enxertia hipocotiledonar de maracujazeiro azedo em porta-enxertos de

Caracterização agronômica, quantidade e qualidade do maracujá-azedo na Região da Serra de Cuité-PB

“…O Plantio P1 apresentou os melhores resultados, tanto com relação ao diâmetro médio das plantas, número e produção de frutos por planta (kg) do maracujá-amarelo, quando comparado com o plantio P2 (Tabela 1). Esses resultados podem estar relacionados ao maior vigor das plantas cultivadas nas condições do P1, maior diâmetro médio do caule (2,39 cm) com relação ao P2 (1,81 cm), assemelhando-se aos encontrados por Santos et al (2016) que foram 2,10, 1,68, 1,99 e 2,63 cm. Para números de frutos e produção por planta (kg), esses dados foram inferiores aos encontrados por Kist;Manick;Boaro (1995), com 153 frutos e 82,24 kg.planta -1 , respectivamente.…”

Advances in passion fruit (Passiflora spp.) propagation

“…The most used methods were cleft, simple slot or splice graft (MACHADO et al, 2015). Other methods have been reported in the literature such as side grafting, approach grafting, hypocotyledonary grafting and micrografting (LIMA et al, 1999;SANTOS et al, 1999;SILVA et al, 2005;RIBEIRO et al, 2008;RONCATTO et al, 2011a;2011b;NOGUEIRA FILHO et al, 2005; 2010; 2011; ALEXANDRE, 2013; MACHADO et al, 2015;SANTOS et al, 2016b).…”

“…The cuttings have an advantage which is the cloning providing a higher uniformity to the obtained grafts (JUNQUEIRA et al, 2002;CHAVES et al, 2004). Another alternative to handle differences in diameters of parts involved in the grafting is the hypocotyledonary graft (NOGUEIRA FILHO et al, 2005;CAVICHIOLI et al, 2009b;SANTOS et al, 2016b).…”

“…A hypocotyledonary graft has been evaluated with different combinations of graft and rootstock and in general has shown results with a high percentage of survival and graft growth (SANTOS et al, 2016b). In this type of grafting, the technique of cleft graft is used and also different tying materials can be successfully utilized (SANTOS et al, 2016b) such as adhesive tape, spring plastic graft clip and metallic hair clip ( Figure 5). SANTOS et al (2016b) state that some advantages in using graft clips includes practical, fast and easy handling, less time to fix it in the rootstock and its reuse after disinfestation.…”

Germination and interspecific grafting of passion fruit

“…alata, P. cincinnata, P. gibertii, and P. mucronata were higher than 90%, whereas Santos et al (2016) reported that the rates of development and survival of sour passion fruit plants grafted on P. edulis, P. gibertii, P. alata, and P. cincinnata were higher than 88%.…”
