| ABSTRACT The flowering time is regarded as an important factor that affects yield in various crops. In order to understand how the molecular basis controlling main components of earliness in tomato (Solanum lycopersicum L.), and to deduce whether the correlation between fruit weight, days to flowering and seed weight, is caused by pleiotropic effects or genetic linkage, a QTLs analysis was carried out using an F2 interspecific population derived from the cross of S. lycopersicum and S. pimpinellifolium. The analysis revealed that most of the components related to earliness were independent due to the absence of phenotypic correlation and lack of co-localization of their QTLs. QTLs affecting the flowering time showed considerable variation over time in... |

| Resumen Las poblaciones humanas en la Amazonia forman parte de los ecosistemas en los que viven. La escala y la intensidad de las actividades humanas tienen un impacto significativo en estos ecosistemas, con efecto local, nacional y global. El objetivo del estudio fue evaluar los patrones de manejo de los agroecosistemas en algunas fincas en municipio de Cacoal, Rondônia, Brasil, en algunos términos biofísicos (ambientales) y socioeconómicos (familias), con el propósito de cuantificar el impacto de 30 años de deforestación, relacionados a su proceso de colonización. El estudio fue implementado en quince propiedades rurales dentro de 3 diferentes regiones en el municipio de Cacoal. Pudimos concluir, en las fincas estudiadas, que el área no es factor... |

| Reports of the last decade show that some types of food and spices included in the human diet, such as pepper (Capsicum annuum L.) can have a positive effect on human health. The Mexican pepper germplasm is poorly documented with regard to variety and the amount of phytochemical compounds that it contains. In the present study, the variation of phytochemical compounds was evaluated in nine fruit variants (morphotypes) of wild and cultivated pepper grown in Oaxaca. ANOVA detected significant differences among pepper morphotypes and ripeness stages of fruits; vitamin C, total phenols, flavonoids, P-carotene, coordinated chromatic of color, and capsaicinoids. The highest values of vitamin C were found in 'Tabaquero', 'Guero' and 'Costeño' morphotypes (151.6... |
