ABSTRACT: Tamarillo (Solanum
betaceum Cav. Syn Cyphomandra betacea Cav.) Sendt is a small tree native to the subtropical Andean region of South
America from Colombia to Chile, popularly known as arboreal tomato, belonging
to the family Solanaceae. The objective of this study was to evaluate the
physicochemical characteristics of fruits and the germination of tamarillo (Solanum betaceum) seeds produced in the Caparaó-ES and MG regions. The following
procedures were performed: Fruit and peel biometrics; fruit weight; pulp and
peel weight; thousand-seed weight, pulp and peel yield and fruit dry mass. In
the physicochemical analysis, the following parameters were determined: pH; soluble solids;
titratable acidity and ratio. For the analysis of the
physiological quality of the seeds, different temperatures (20°C; 25°C; 30°C and 20°C - 30°C) were evaluated in the presence and absence
of light and the following was determined: Seed moisture content; germination;
germination speed index; germination mean time; shoot length; root and total
seedling dry mass. Tamarillo in the region of Caparaó-ES presents greater chemical characteristics of the fruits,
germination and vigor, and in the region of Caparaó-MG
presents greater physical characteristics of the fruits. Tamarillo can
germinate both in the presence and absence of light, although in the presence
of light, it presents greater vigor.
