RESUMO

The inheritance of aluminum tolerance in tomato. Two Lycopersicon esculentum lines, one tolerant BGH 588 (PI 367991) and other sensitive BGH 402 (PI 367977) to Al toxicity in both soil and nutient solution were used to investigation the inheritance of the Al tolerance in soil with saturation level of Al. the parental lines and the reciprocal hybrids were grown in the field. The ?F IND. 1?s were selfed and that both parental lines had same vegetative growth in field conditions differing only in fruit characteristics. A clay soil classified as ?Latossolo Vermelho Escuro, Distrófico, Unidade Limeira ? Fase Muito Àcida? was used because of its high level of Al saturation. To this sol was added six different amounts of lime in order to obtain the following Al levels of saturation: 95, 80, 60, 40, 30 and 2%. It was observed that differences between the lines were more clearly didtinguishable in the 60 ? 30% interval of Al saturation. In the 95% level both genotypes were equally affected in growth. In the 2% level, the vegetative growth of both lines were normal and similar to each other. Differences however were observed between the tolerant and intolerant lines in the intermediary levels of Al saturation ...Note: The complete abstract is available with the full electronic digital thesis or dissertations
