Abstract

Sunspot affects tomato fruit quality. Its severe
symptoms contrast with the rest normally ripened red fruit. Its
signs are from internal white tissue (IWT) to distinctive yellow
peduncle sectors (YS) or under the ripened peduncle skin
(YSD). The objective of this research work was to determine
the action of sun radiation on sunspot occurrence. Thus, 30
plants were selected out of four varieties, six per treatment and
the control. Selected fruits for the control treatment (T1) were
uncovered. The other five treatments were covered by a
cylindrical filter. The following filters were applied: green
cellophane (T2), red cellophane (T3), blue cellophane (T4) and
aluminum foil (T5). Results proved a high sunspot effect, since
all genotypes showed symptoms in every treatment. These
results indicate a genetic predisposition to sunspot, but its
intensity and severity depended on the spectral light
composition transmitted to fruits. A significant interaction was
recorded between genotypes and sun radiation quality.
