Ethylene evolution rate and percentage of soluble solids of thornless blackberry ( Rubus sp.) increased with maturity and ripening, while titratable acidity decreased. Following harvest of “purple” fruits, their respiration and ethylene evolution rates increased during 7 days at 25°C. Ethylene evolution rates and differences in shelf-life among cultivars were inversely related. We conclude that thornless blackberry is a climacteric fruit.
