Watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai, 1916) or watermelon is a plant of the Cucurbitaceae family, originally from tropical Africa.
Watermelon is an annual plant, with climbing herbaceous stem, large and hairy leaves with three lobes, male flowers and female flowers, voluminous round or oval fruit, which reaches a weight of 20 kg.
The fruit is a false berry (peponide), very massive; the peel is smooth, hard and relatively thin, green in color with various streaks and patches lighter, white or yellowish; the interior is red (or, less frequently, yellow, orange or white depending on the variety) and rich in seeds, which can be black, white or yellow. The pulp is made up of over 90% of water and also contains a fair amount of sugars, especially fructose, and vitamins A, C (8.1 mg per 100 g of fruit), B and B6.
