Fruit quality of watermelon hybrids with seeds
This investigation was aimed to evaluate the quality postharvest of two seeds watermelon hybrids grown under conventional management. The quality characteristics analyzed were: fresh mass; longitudinal and transverse diameter; fruit format index (IF: DL/DT); shell thickness; pulp firmness; soluble solids; titratable acidity; pH; SS/TA ratio; total soluble and reducing sugars; soluble pectin; vitamin C; total carotenoids; lycopene; yellow flavonoids; anthocyanins and total extractable polyphenols. A completely randomized design (CRD) was carried out. The results were submitted to analysis of variance (ANOVA). Those hybrids showed fresh mass, DL/DT, color, soluble solids, titratable acidity and SS/TA satisfactory for commercialization; with emphasis on the 'Boston' hybrid which showed higher soluble solids content (9.90 ° Brix), total soluble sugars (6.66%) and SS/TA (86.24). For bioactive compounds, 'Boston' hybrid had higher mean values for total carotenoids (2.03 mg 100g-1) and yellow flavonoids (3.21 mg 100g-1), however, the 'Quetzali' hybrid was highlighted for extractable total polyphenols (194.36 mg 100g-1), and thus can be used to promote human health. Although the hybrids tested have shown to be qualitatively favorable to consumption, these results indicate a narrowing of the genetic base, which makes it necessary the evaluation of other watermelon seeds hybrids.
