“…According to Pina et al (2012), the proliferation and adhesion of a tissue callus can occur during the compatible and incompatible grafting of different Prunus combinations up to one week after grafting. However, the formation of new cambium derived from the tissue callus appears to be delayed in heterografts and/or interspecific grafts compared with that in homografts and/or intraspecific grafts.…”

“…Given the complexity of such interactions, early diagnosis is extremely difficult, and in most cases, no external symptoms are observed for several years (Pina and Errea 2008;Zarrouk et al 2006, Pina et al 2012Pereira et al 2014a).…”

“…The localized incompatibility, in turn, displays malformation in graft union due to physiological and morphological alterations resulting in impaired and even fractured union after several years of grafting (Errea 1998). The alterations include functionality disturbances in newly formed vascular cambium, lack of tissue differentiation, imperfect lignification and lack of vascular continuity, which might cause rupture of the graft union (Errea 1998, Zarrouk et al 2006Zarrouk et al 2010;Pina et al 2012).…”

“…A incompatibilidade de enxertia é caracterizada pelo desenvolvimento anormal do enxerto, em razão de diferenças anatômicas, fisiológicas, bioquímicas e moleculares, o que resulta em prejuízo visível ou não à união do enxerto, além de crescimento vegetativo retardado, baixa produtividade e, em casos severos, morte da planta (Nocito et al, 2010;Pina et al, 2012;Pereira et al, 2014). Alguns autores atribuem a incompatibilidade entre pereira e marmeleiro à liberação de cianeto na interface do enxerto (Gur et al, 1968;Moore, 1986;Nocito et al, 2010), processo conhecido como cianogênese e que ocorre pela hidrólise de glicosídeos cianogênicos.…”

“…Dessa forma, é possível que o mecanismo de incompatibilidade atuante nessas três combinações seja outro. Outros mecanismos estudados atualmente incluem: diferenças entre compostos fenólicos do porta-enxerto e da cultivar-copa, distúrbios hormonais e problemas na comunicação celular (plasmodesmas) do porta-enxerto e da cultivar-copa (Pina et al, 2012;Hudina et al, 2014;Pereira et al, 2014).…”
