Conteúdo: | Watermelons [Citrullus lanatus (Thunb.) Matsum and Nakai] were grown  at Leesburg and Gainesville to evaluate the effect of environmental factors on fruit watersoaking and on seed quality. Watersoaking was related to cultivar and was enhanced by irrigation. Watersoaking in fruit of Charleston Gray at both locations was negligible, but Smokylee developed 34% watersoaking at Leesburg and 83% at Gainesville. An increase in the water rate from 1 to 5 inch/week at Leesburg increased the occurrence from 45% to 80% in fruit at the second harvest. At Gainesville,an increase in irrigation rate from 0 to or 5 inches/week significantly increased the watersoaking occurrence from about 70 to 90%. No significant correlation was found between watersoaking severity and maturityfrom the pink to over-mature stage. Shading fruit in the field during development reduced the surface temperature by 30 F over non-shaded fruit but did not affect watersoaking. Seed germinations from fruit randomly selected at the last harvest was lower at Leesburg (66%) than at Gainesville (83%). Shading fruit led to a reducation in germination at Leesburg.
