- Abstract
Red drupelet reversion (RDR) is a physiological disorder in which blackberry drupelets revert from black to red, losing their commercial value. RDR has been associated with mechanical damage caused by vibrations during transport. The goal of the present study was to construct a portable vibration system to quantify RDR progression in different blackberry cultivars. The system was integrated with an electrical signal generator, a monoaural amplifier, a subwoofer type speaker, and an oscilloscope. This system generates vibration intensities reached during fruit commercial transport (10 Hz and 0.5 g's). To induce RDR, blackberry clamshells cv. 'Tupi' were placed in the portable system and subjected to different vibration times. RDR was observed immediately after fruit was subjected to 5 min vibration. To evaluate RDR progression in different cultivars, blackberry clamshells 'Ak234′, 'Am151′, and 'Tupi' were subjected to vibration during different times; and analyzed after storage (0 to 5 d). 'Tupi' blackberries reverted more rapidly than 'Am151′ and 'Ak234′ cultivars, suggesting that 'Tupi' was more susceptible to RDR. These results highlight that portable vibration system could be a useful and fast tool to evaluate resistance to RDR in blackberries.
