“…For example, once an organization brings in a group of new employees with new knowledge to revitalize one of its strategic business units, it should continuously check for abnormalities in terms of decreased organizational commitment, decreased job satisfaction, increased conflicts, increased stress levels, and/or increased employee turnover among other things. However, early observations may not always correlate with long-term graft survival (Andrews & Marquez, 1993). On the other hand, sometimes it may take years before symptoms of abnormalities become visible (Gulen, Celik, Polak, & Eris, 2005).…”

“…Há um consenso geral de que quanto maior a distância taxonômica entre porta-enxerto e copa, menores são as chances de formação de uma união bem sucedida. Isto teoricamente significa que o sucesso de uma determinada combinação segue a seguinte ordem: intraclonal> intraespecífica> Intergenérica > intrafamiliar (Andrews & Marquez, 1993). Desta forma, um programa de melhoramento visando à obtenção de novas cultivares de porta-enxertos, deve levar em consideração a compatibilidade entre estes e as cultivares copa.…”

RESUMOHíbridos de tangerina Sunki vs Poncirus trifoliata cv. Rubidoux são uma nova geração de porta-enxertos para a citricultura que apresentam o potencial de reunir características como, formação de plantas com menor porte de copa, elevada eficiência produtiva e produção de frutos com alta qualidade de suco. O objetivo do presente estudo foi avaliar híbridos de porta-enxertos de citros, em competição com limão 'Cravo' (Citrus limonia Osbeck), enxertados com laranja 'Valência' (Citrus sinensis (L.) Osbeck), visando novas seleções de porta-enxertos para a citricultura. Foram avaliadas 48 combinações de laranja 'Valência' com híbridos utilizados como porta-enxerto e o limão Cravo. As variáveis analisadas foram: compatibilidade entre copa e porta-enxerto, desenvolvimento vegetativo das plantas, produção, eficiência produtiva, massa dos frutos, diâmetros equatorial e polar dos frutos, rendimento do suco, teores de sólidos solúveis totais (SST -°Brix), acidez titulável (AT), "ratio" (Relação SST/AT), índice tecnológico (IT). Foi calculado um índice de desempenho para cada combinação copa/porta-enxerto. Para isso, foram previamente determinados índices para as variáveis produção de frutos, rendimento de suco, "ratio" e índice tecnológico. Os resultados obtidos permitiram concluir que ao menos 18 híbridos enxertados com laranja 'Valência' mostraram melhores índices de desempenho em relação ao limão 'Cravo'. Termos de indexação: citrandarins, Citrus, índice de desempenho.Alternative rootstocks for Valencia orange cultivation in the southwest region of the state of São Paulo SUMMARYHybrids of mandarin Sunki vs Poncirus trifoliata cv.

“…The greater the taxonomic distance between stock and scion the smaller the chances of forming a successful graft union. This means that the theoretical success of a particular graft union combination is intraclonal > interclonal > intraspecific > interspecific > intrageneric > intergeneric > intrafamilial (Andrews and Marquez, 1993). Also, different taxa may differ in the degree of relatedness required for the formation of successful graft unions (Rom and Carlson, 1987).…”

Commercial fruit trees are usually formed by the combination of a rootstock and a scion to broaden the adaptability of scion cultivars to soil and climatic conditions, facilitate agricultural management, and/or increase productivity. In the different cultivated species of the genus Prunus, rootstocks having a wide range of uses are scarce, because of rootstock/ scion graft incompatibilities that prevent the establishment of a strong and lasting functional union. Graft incompatibility is a problem in cherry, almond, and apricot than in peach or plum. In general, closely related cultivars and species tend to be compatible, but taxonomically distant plants often manifest incompatibility. This review will focus on the knowledge currently available on the metabolic response during the formation and establishment of the stock/scion graft union in order to help the effort for identify future metabolic markers to be used in breeding programs. The physiological, metabolic and molecular mechanisms that cause incompatibility remain unclear and several hypotheses have been proposed to explain it, mostly based on herbaceous species. Few studies are available to explain incompatibility in woody plants. Various phenolic compounds are known to affect cell division, development and differentiation at the graft union. Flavonol (catechins and proanthocyanidins) concentrations increase shortly after grafting and, as a result of the stress induced during the healing response, vacuolar membrane disruption occurs resulting in the escape of phenols from the vacuole into the cytoplasmic matrix, causing dysfunctions in the growth of certain tissues (xylem and phloem), interference with the synthesis of lignin or inducing hormonal imbalances. All these abnormalities result in mechanical weakening of the union, which may manifest during the first year after grafting (translocated incompatibility) or may appear several years later (localized incompatibility), leading to major economic losses. More research is needed to fully understand the mechanism of graft incompatibility, particularly in woody plants. This knowledge is essential to develop molecular markers useful in rootstock breeding programs.
