Resumo(s)
The collection of tomato (Lycopersicon esculentum Mill) Portuguese Bank of Plant
Germplasm of INRB, brings together dozens of hits in characterization. This paper
presents results of color versus lycopene content of tomato accessions of some
Portuguese Plant Germplasm Bank (2011-2012), in order to indirectly estimate the
levels of lycopene in tomato fresh/chilled accesses via colorimetric analysis. The study
took place in 10 tomato accessions, fresh and chilled to 5 ° C. The changes in color
/pigment during the ripening of tomato are characterized by reduced chlorophyll and a
rapid accumulation of carotenoids, particularly lycopene. Sometimes, due to the
convenience and ease of use of color measuring the content of lycopene in the tomato
pulp can be determined without the need to conduct a chemical analysis, in that there
is a good correlation between the color of the fruit and lycopene content (adapted
D'Souza, et al., 1992, Arias, et al., 2000 cited by Carvalho, et al., 2005). For all this
justifies the existence of quality control tools across the row, starting at the selection
of genotypes in breeding programs of tomato. The homogenized pulp is considered
one of the best alternatives correlation associated with the chromaticity coordinate a.------The collection of tomato (Lycopersicon esculentum Mill) Portuguese Bank of Plant
