The article will tell you what family it belongs to, how it grows, the beneficial properties of the fruit and contraindications for eating it.
What is watermelon: a berry, fruit or vegetable
Watermelon is an annual herbaceous plant of the Watermelon genus of the Cucurbitaceae family. It belongs to the melon crops. From a botanical point of view, watermelon fruits are berries.
However, due to the discrepancy between the characteristics of the fruit and the standard description and photo of the berries (the rind is too thick), watermelons are called pumpkin or “false” berries.
What it looks like, what they are, what color
The fruits differ in shape, size and color depending on the variety. Pumpkin has a spherical, oval or flattened shape. Weighs from 2 to 25 kg. The color of the hard crust is most often green with darker stripes or spots.
The surface is smooth in most cases. Between the rind and the juicy pulp there is a white layer ranging from a few millimeters to 5 cm thick. The pulp of watermelons is red, pink or raspberry in color, juicy, sweet and aromatic.The seeds, 5 to 14 mm in size, are flat, edged, dark brown or white, and are found in the pulp.
Thanks to selection, a large number of varieties and hybrids of watermelon have been obtained. Their fruit weight can range from 10 g to 125 kg. The color of the fruit's rind can be not only dark green or striped, but also black, white, yellow, spotted or marbled. The flesh is also white, yellow or creamy orange.
There are also unique varieties of watermelons. For example, a representative of the Densuke variety has a rich black color without a single stripe; it is grown only on the Japanese island of Hokkaido.
Seedless watermelons are also common, including those with yellow flesh. This variety was bred for those who are tired of extracting seeds.
Interesting! Currently, Japanese breeders have developed new varieties with a traditionally dark green striped color, but with a square and pyramid shape.
