“…Very few studies have been publishing on A. angustifolia grafting (GURGEL; GURGEL-FILHO, 1967;KAGEYAMA;FERREIRA, 1975;IRITANI, 1997;ANSELMINI;ZANETTE, 2008), and techniques for the production of grafted seedlings remain to be defined.…”

Araucaria angustifolia is an endangered conifer species of South America that has been over exploited for timber. To incentivize Araucaria angustifolia planting is essential and may play a key role on the conservation of this species and the ecosystems that depend on it. Hence, techniques that allow the production of seedlings with attributes that may entice farmers to plant A. angustifolia trees are very important. Grafting may permit the selection of female trees and the production of precocious plants that will produce high quality seeds. The aim of this study was to determine the best season of the year to graft. Three-year-old seedlings were used as rootstock and orthotropic branches of young plants were used for scion collection. The technique used for the grafting was the bark patch. This procedure was carried out in the beginning of each season in 2007 and 2008, with a total of 160 grafted plants. Grafting carried out in the beginning of autumn had a 50 % success rate. Grafting success was negligible for all remaining seasons. In conclusion, grafting through bark patching is a viable technique for the production of A. angustifolia seedlings. Future research should be carried out to produce grafted seedlings in large-scale.

“…It is important to point out that the compatibility between rootstock and graft is fundamental for successful grafting, and may be related to physiological and anatomical factors (NAVARRO 1988;PIO et. al., 2001;ANSELMINI and ZANETTE, 2008). Therefore, histological analysis can provide the characterization of structures involved in the union of tissues and greater understanding of grafting results (ESTRADA -LUNA et al, 2002).…”

The present study aimed to describe histological traits of the graft welding process and evaluate the effect of rootstocks on the physical and chemical traits and the productivity of sour passion fruit populations. The experiment was arranged in a randomized block design, in a 4x2 + 4 factorial scheme (cultivars / canopy x rootstocks), three replicates and nine plants per plot. Commercial cultivars and populations and Passiflora alata and P. nitida rootstocks, in addition to ungrafted plants were used as canopy. Cleft grafting was the grafting type adopted. Traits analyzed such as productivity and physical and chemical quality of fruits were submitted to analysis of variance and compared by the Tukey test. The canopy morphology was evaluated according to descriptors of the Ministry of Agriculture, Livestock and Supply. Grafting was carried out for each graft/rootstock combination for histological analysis. Sections were obtained by freehand cuts, stained and mounted on semi-permanent slides, examined under optical microscope and photomicrographed. Rootstocks affected the early cultivation and reduced productivity and number of fruits of passion fruit populations. Grafting did not affect the quality of fruits or the canopy morphology. Considering the complete culture cycle, P. alata species is able to be used as rootstock. The anatomical study demonstrates the occurrence of better compatibility in the connection of P. edulis tissues on P. alata, compared to grafting on P. nitida.Análise histológica e desempenho de populações de maracujazeiro-azedo sob diferentes porta-enxertos resistentes ao fusarium spp Resumo -O objetivo do presente trabalho foi descrever as características histológicas do processo de soldadura da enxertia e avaliar a influencia dos porta enxertos sobre as características físicas e químicas do fruto e na produtividade de populações de maracujazeiro azedo. O delineamento utilizado foi o de blocos ao acaso, num esquema fatorial 4x2+4 (cultivares/copas x porta enxertos), com três repetições e nove plantas por parcela. Foram utilizadas como copa cultivares comerciais e populações e os porta enxertos Passiflora alata e P. nitida, além do pé-franco. O tipo de enxertia foi o convencional por garfagem no topo em fenda cheia. As características analisadas como produtividade e qualidade físico química dos frutos foram submetidas à análise de variância e comparadas pelo teste de Tukey. E a morfologia da copa foi avaliada de acordo com descritores do MAPA. Foi realizada a técnica de enxertia de cada combinação enxerto/porta enxerto para a analise histológica, onde as secções foram obtidas à cortes a mão livre, coradas e montadas em lâminas semipermanente e analisadas sob microscópio óptico e fotomicrografadas. Os portas enxertos influenciaram no período inicial de cultivo reduzindo a produtividade e o número de frutos das populações de maracujazeiro, e a enxertia não influenciou na qualidade dos frutos e na morfologia da copa. Considerando o ciclo completo da cultura, a espécie P. alata possui condições de ...

“…Pereira et al (2009), com a microenxertia interespecífica ex vitro, obtiveram valores de pegamento das combinações P. edulis f. flavicarpa x P. edulis f. flavicarpa, P. edulis f. flavicarpa x P. cincinnata, P. edulis f. flavicarpa x P. alata, P. edulis f. flavicarpa x P. setacea, de 30,3; 10; 1,6 e 0%, respectivamente. Em outras espécies também se utiliza a microenxertia, como em eucalipto (BANDEIRA et al, 2007), citros (SINGH et al, 2008), araucária (ANSELMINI et al, 2008), Arabidopsis thaliana (NOTAGUCHI et al, 2009), tomateiro (COUTINHO et al, 2010 e Nicotiana attenuata (FRAGOSO et al, 2011).…”

O objetivo foi avaliar a metodologia de enxertia pela modalidade garfagem no topo hipocotiledonar em fenda cheia, utilizando miniestacas adultas de segmentos apicais de P. edulis f. flavicarpa, P. edulis, P. alata, P. mucronata e P. foetida e internodais de P. mucronata. O experimento foi conduzido em casa de vegetação equipada com sistema de irrigação com nebulização intermitente, do Centro Universitário Norte do Espírito Santo (CEUNES), da Universidade Federal do Espírito Santo (UFES). Os índices de pegamento nas combinações de P. edulis f. flavicarpa/P. edulis f. flavicarpa, P. edulis/P. edulis f. flavicarpa, P. alata/P. edulis f. flavicarpa, P. mucronata/P. edulis f. flavicarpa, P. foetida/P. edulis f. flavicarpa foram de 90; 90; 68; 80 e 90, respectivamente. A metodologia empregada é uma nova opção de enxertia para essas espécies do gênero Passiflora.
