Watermelon (Citrullus lanatus L. sin. C. vulgaris L.) is a drought-resistant vegetable plant. It is grown for its fresh fruit. The fruits are large, with the green bark of different nuances and the red, pink or orange core. Its main feature, that it is zemos, is due to the water content (about 92%). The core contains a variable number of seeds but there are also watermelons without seeds.
