Resumo: | Recently, in Viçosa (MG), a region of vegetable crop producing, tomatoes of Santa Clara cultivar, Lycopersicum esculentum (Solanaceae), that showed potential use for breeding programs, aiming to increase the shelf life of the fruit were identified. However, plants from the mutant ‘firme’ have precocious fealf senescence and reduction of the average fruit size when in homozygous background. The objective of the present study was the evaluation of the pigment levels in the leaves on different development positions and stage, utilizing the method described by Lichtenthaler (1987) and the SPAD (Soil Plant Analytical Division Value) in heterozygous mutant related to the progenitor Santa Clara cultivar and the homozygous mutant ‘firme’. Thus, two experiments containing two plants per vase grown in greenhouse and arranged at complete randomized way were set up. The data obtained through the Lichtenthaler (1987) method showed that the chlorophyll and carotenoid pigments were degraded earlier in the homozygous mutant ‘firme’ in comparison to Santa Clara cultivar. While using the SPAD the heterozygous plants had similar rates of chlorophyll degradation to the Santa Clara cultivar. Based on data, it was possible to conclude that the mutation in heterozygous stage containing Santa Clara in its background had its effects on biochemical characteristics restored |

No entanto, essas plantas promissoras, denominadas de ‘mutante firme’, apresentam senescência foliar precoce e redução do tamanho médio dos frutos, quando o gene se encontra no estado homozigótico recessivo, sendo visualmente normal quando no estado heterozigótico. Assim o objetivo do presente trabalho foi avaliar os níveis de pigmentos foliares em diferentes posições da planta e em diferentes tempos de cultivo, pelos métodos descritos por Lichtenthaler (1987) e pelo índice SPAD (Soil Plant Analylitical Division Value), para verificar a ocorrência ou não de comportamento diferencial de indivíduos heterozigotos em relação aos progenitores Santa Clara e ao mutante ‘firme’. Para isso, foram realizados dois experimentos, empregando-se plantas cultivadas em vasos, submetidas a condições de casa-de-vegetação e arranjadas em delineamento inteiramente casualizado. Os resultados das análises, pelo método de Lichtenthaler (1987) mostraram que a clorofila e os pigmentos carotenóides são degradados mais precocemente no mutante ‘firme’ em relação à cultivar Santa Clara. Além do que, pelo índice SPAD observou-se que os indivíduos, portando a mutação no estado heterozigótico, e os da cultivar Santa Clara apresentaram taxas similares de degradação de clorofila em relação ao tempo de cultivo. Com isso, pode-se concluir que a mutação no estado heterozigótico, em cruzamento com Santa Clara, tem seus efeitos restaurados para esses caracteres bioquímicosUniversidade Estadual De Maringá2008-04-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/211010.4025/actascibiolsci.v25i1.2110Acta Scientiarum.
