Strawberries - useful properties and contraindications

Strawberry is a widespread herbaceous plant belonging to the family of pink (strawberry type). Representatives of this species have an erect stem from 13 to 45 cm long, collected in the rosette trifoliate bluish-green leaves on long petioles, creeping shoots (“antennae”) and a thick rhizome of brown color. The leaf blades of the plant have an ovoid or rhombic or oval shape and a wide toothed border. The thyroidal inflorescence of a culture consists of 5–12 large white flowers. The fruit of strawberry is a polyunus of spherical or ovoid shape, which is formed from an expanded receptacle. At full maturity, the berries acquire a cherry-red color and a pleasant aroma.

According to scientists, the direct “ancestor” of strawberries is wild strawberry. A new representative of the genus appeared when the specified species was adapted to unexpectedly changed habitat conditions. Researchers believe that wild strawberry originally formed a double set of chromosome subspecies, which later crossed again with the original species. The result of re-crossing was the emergence of a new representative of the genus - strawberries.

However, the active work on the cultivation of this culture began in Europe much later - in the XV century. At the beginning of the XVIII century, breeders began to produce strawberry varieties capable of adapting to the capricious climatic conditions, producing a rich and beautiful crop. To date, there are hundreds of varieties of this plant, differing in their predisposition to soil types, frost resistance, size, color and taste of berries.
