Diversity assessment in the Portuguese genebank collection of tomato (Solanum l...
Pinela, José; Montoya, César; Martins, Valter; Nunes, M. Eugénia; Rocha, Filomena; Lopes, Violeta R.; Barata, Ana Maria; Carvalho, Ana MariaTomato germplasm is source of variability used by plant breeders to develop improved cultivars and part of the natural heritage to be preserved. In this study, the diversity among twenty Portuguese tomato accessions was evaluated, considering morphological and agronomic descriptors, molecular data, and compositional aspects. The tomato accessions captured 77.5% of the total 19 alleles detected. Important inform...
Phenolic composition and antioxidant properties of ex-situ conserved tomato (So...
Pinela, José; Montoya, César; Carvalho, Ana Maria; Martins, Valter; Rocha, Filomena; Barata, Ana Maria; Barros, Lillian; Ferreira, Isabel C.F.R.Tomato (Solanum lycopersicum L.) local varieties represent a reservoir of genetic diversity for desirable quality traits. In this study, a representative collection of table tomato germplasm conserved ex-situ in the Portuguese Gene Bank was characterized for its polyphenols composition and antioxidant capacity. Phenolic acids, such as caffeic and p-coumaric acids bounded to a hexose and 5-O-caffeoylquinic acid,...
Aspectos bioquimicos y bioactivos de catorce accesos de tomate (Solanum lycoper...
Montoya, CésarEl tomate es uno de los vegetales más consumidos en el mundo y es el componente más importante de la dieta mediterránea. Hoy en día los consumidores son cada vez más conscientes y están mejor informados acerca de los beneficios a la salud que proporcionan los alimentos más allá de su función nutricional básica. Los principales compuestos del fruto de tomate son: carotenoides (β-caroteno y licopeno), vitaminas (...
Profiling antioxidant, vitamins and other phytochemicals in Portuguese Tomato L...
Montoya, César; Pinela, José; Barros, Lillian; Carvalho, Ana Maria; Rocha, Filomena; Ferreira, Isabel C.F.R.Tomato (Solanum lycopersicum L.) is a key element of the Mediterranean diet and a source of nourishment for the world's population [1]. During the evolution and domestication of this plant, genetic modifications and severe inbreeding of limited genotypes occurred [2]. As a result, a wide range of fruits with different morphological and sensorial attributes gave rise to a number of landraces that have been culti...
Caracterização química de uma coleção de germoplasma de variedades tradicionais...
Montoya, César; Pinela, José; Barros, Lillian; Carvalho, Ana Maria; Rocha, Filomena; Barata, Ana Maria; Ferreira, Isabel C.F.R.O tomate (Solanum lycopersicum L.) é uma importante fonte de nutrição para a população mundial [1]. Ao longo do seu processo evolutivo e de domesticação, esta espécie sofreu alterações genéticas e fenómenos de endogamia severa que levaram ao surgimento de variedades com diferentes atributos morfológicos e sensoriais [2]. Estas variedades têm sido cultivadas localmente e representam um reservatório de diversidad...
