Interpretive Summary: Watermelon plants were grown in Lane, Oklahoma. Fruit weight, dimensions, and quality (sugar, firmness, lycopene content) of seeded and seedless varieties were measured. Watermelons from vigorous plants (determined by plant length, width, and a visual estimate of plant health) weighed more than those from non-vigorous plants. Watermelon shape, determined by length, circumference, and their ratio, did not change significantly from fruit harvested from vigorous or non-vigorous plants. Rind thickness was increased in watermelons on non-vigorous plants. Lycopene, sugar, and firmness tended to be lower in non-vigorous plants. These results indicate that watermelon quality is dependent on the overall health of the plant.

Technical Abstract: Watermelon (Citrullus lanatus var. lanatus) plants were grown in Lane, Oklahoma. Fruit weight, dimensions, and quality (SSC, firmness, lycopene content) of seeded and seedless varieties were measured. Watermelons from vigorous plants (determined by plant length, width, and a visual estimate of plant health) weighed more than those from non-vigorous plants. Watermelon shape, determined by length, circumference, and their ratio, did not change significantly from fruit harvested from vigorous or non-vigorous plants. Rind thickness was increased in watermelons on non-vigorous plants. Lycopene, SSC, and firmness tended to be lower in non-vigorous plants. These results indicate that watermelon quality is dependent on the overall health of the plant.
