Storage characteristics of small watermelon cultivars.

Two newly released cultivars, Mickylee and Minilee, plus 2 other cultivars, Baby Fun and Sugar Baby, were stored at various temperatures from 1 to 21 deg C for up to 4 weeks plus 1 week at 21 deg in trials over 2 years. All cultivars were susceptible to chilling injury (CI) when stored below 7 deg ; however, Minilee was less susceptible than the other cultivars. CI increased with storage length. Conditioning at 26 deg for 3 days before storage at 1 deg reduced CI and increased the percentage of marketable watermelons after storage. Decay percentage increased with storage time and was highest in fruits held at 1 deg where CI led to decay. The flesh of Mickylee and Minilee was firmer than that of the other cultivars and Mickylee and Minilee retained their firmness better during storage. TSS concentration decreased with increased storage temperature. Minilee watermelons were superior to the other cultivars in postharvest storage potential and exhibited the least CI and decay.
