“…Desempenham papel importante no processo de enxertia, pois, participam da estrutura das plantas e estão envolvidos em um grande número de rotas metabólicas, bem como na resposta das plantas ao ambiente e na interação entre cultivar-copa/ portaenxerto (RODRIGUES et al, 2002;TELLES et al, 2009;.…”

“…Inúmeros autores têm relacionado à incompatibilidade de enxertia com diferenças quantitativas e/ou qualitativas no conteúdo de fenóis, além de mudanças na atividade das enzimas que regulam a síntese desses compostos (ERREA, 1998;RODRIGUES et al, 2002;MNG'OMBA et al, 2008;PINA & ERREA, 2008;TELLES et al, 2009;ZARROUK et al, 2010;YUAN et al, 2011;PEREIRA et al, 2013). Segundo ERREA (1998), os compostos fenólicos estão implicados em todos os eventos envolvidos no processo de enxertia.…”

“…Em casos brandos, nota-se apenas a redução do vigor, podendo ser até um efeito desejável, já que favorece a produção de frutos em detrimento do crescimento vegetativo, sendo conhecido em alguns casos como efeito ananizante (MARTÍNEZ-BALLESTA et al, 2010;DARIKOVA et al, 2011;TOMBESI et al, 2011;GJAMOVSKI & KIPRIJANOVSKI, 2011). Porém, em casos de incompatibilidade aguda, a cultivar-copa e o portaenxerto nem sequer chegam a unir-se, ou, em casos em que ocorre essa união, o enxerto defi nha e morre ainda nos primeiros meses após a enxertia (RODRIGUES et al, 2002;HARTMANN et al, 2010).…”

“…In addition, this enzyme was reported to be implicated in process related to graft establishment (Deloire and Hébant, 1982;Feucht et al, 1983;Schmid and Feucht, 1985). Higher peroxidase activity in grafted rootstocks was related to graft incompatibility in Prunus species (Rodrigues et al, 2002), and it has been suggested that differences in peroxidase concentration between rootstock and scion may cause bad vascular connections (Santamour, 1992). Graft incompatibility of peach rootstocks is an important characteristic to be assessed in breeding programs.…”

Changes in cell and tissue organization and in peroxidase activity have been analyzed to find early markers to predict graft incompatibility occurrence in peach/plum combinations (Prunus persica/Prunus spp.) at 5 months after grafting in the dormancy period. Different compatible and incompatible peach/plum grafts were grown for 5 months in a nursery. The cellular study of the graft interface revealed structural changes associated with graft incompatibility symptoms. The main structural features were cambium cell disorganization, less differentiation of vascular tissues, degeneration of phloem and xylem cells, and accumulation of phenols at the graft interface after 5 months of graft development. The peroxidase study was performed during dormancy and the vegetative growth period, and revealed a significant increase in peroxidase activity in the incompatible unions, with significant differences between compatible and incompatible grafts. Analysis of gel profiles of nonbudded rootstocks and scions revealed an anodal isoperoxidase band [relative front (Rf) = 0.48] present in scions and compatible rootstocks, and another isoperoxidase band (Rf = 0.53) only present in the incompatible rootstocks. Our results show that the analysis of cell organization to detect early structural events and the evaluation of peroxidase activity at graft unions constituted feasible and convenient methods for early diagnosis of graft incompatibility. Also, it was suggested that the presence of band Rf = 0.48 in plum rootstocks and peach cultivars could be used as a marker to predict graft compatibility for peach scions and plum rootstocks.

“…Nevertheless, Rodrigues et al (2002) reports that rootstocks of peach and plum, for example ‗mirabolano', presented higher peroxidase activity, indicating that this species, when grafted onto cultivars with lower activity, present graft-incompatibilities. Moreover, in cherry, cultivars with lower peroxidase activity can predict grafincompatible (Güçlü and Koyuncu, 2012).…”

This study aimed to quantify the class III peroxidase activity in young plants of different species belonging to Annonaceae botany family, with high potential as a rootstock, for early detection of graftcompatible atemoya (Annona x atemoya Mabb.). The experimental design was randomized block, that evaluated the species araticum-de-terra-fria (Annona emarginata (Schltdl.) H. Rainer 'variety terra-fria'), araticum-mirim (Annona emarginata (Schltdl.) H. Rainer 'variety mirim) and biribá (Annona mucosa (Schltdl.) H. Rainer), with rootstock potential, and atemoya (scion), which were divided into four blocks, each with four plants. The peroxidase was quantified on the stem before grafting. Statistical analysis showed that only the biribá presented different peroxidase activity compared to atemoya plants; and araticum-mirim and araticum-de-terra-fria were similar to atemoya plants. Thus, the peroxidase activity could not be possible or be used as a tool in the early diagnosis of the graft-compatible in atemoya combinations.
