Description
Summary:The graft incompatibility is a problem that causes economic loss to producers and delay in the launch of new cultivars and rootstock because of the long time required for compatibility testing. The aim of this review is to show of the most important and relevant research conducted over the years involving the graft incompatibility in fruit species, specially the genus Prunus. The graft incompatibility is an extremely complex phenomenon that involves anatomical, physiological, biochemical and molecular interactions between scion and rootstock. Being for this reason a difficult problem to analyze. However, it is believed that through a joint analysis of graft incompatibility the understanding of the mechanisms may advance more quickly and so allow the solution for the phenomenon. Key words: grafting, compatibility, hormones, phenols, prunasin. A incompatibilidade de enxertia e um problema que, alem de prejuizo economico aos produtores, causa atraso no lancamento de novas cultivares-copa e portaenxertos, devido ao longo periodo de tempo necessario para os testes de compatibilidade. O objetivo desta revisao e fazer um apanhado das principais e mais relevantes pesquisas realizadas envolvendo o tema incompatibilidade de enxertia em especies frutiferas, especialmente as do genero Prunus. Incompatibilidade e um fenomeno extremamente complexo, que envolve interacoes anatomicas, fisiologicas, bioquimicas e moleculares entre a cultivar-copa e oportaenxerto. Sendo, por essa razao, um problema de dificil estudo. Porem, acredita-se que atraves de uma analise conjunta dos diversos mecanismos de incompatibilidade, se pode avancar mais rapidamente no entendimento deste fenomeno. Palavras-chave: enxertia, compatibilidade, hormonios, fenois, prunasina.
