Pineapple is a perennial tropical plant belonging to the Bromeliad family. Homeland of this culture are arid plateaus of the central part of Brazil. In the XVI century, the Portuguese, who explored the American continent, discovered this amazing plant and transported it to India and Africa. This culture came to European territory much later - in the middle of the 17th century.
In Europe, pineapples for two centuries were grown in greenhouses. However, in the 19th century, Europeans had the opportunity to transport fresh, tasty and juicy fruits by steamboats directly from plantations located in tropical countries. As a result, the greenhouse cultivation of this plant in Europe has fallen into decay.
Today, the largest pineapple plantations are located on the Hawaiian Islands: local farmers account for up to a third of the world production of these fruits. In addition, Brazil, Thailand, Costa Rica and the Philippines are among the leaders in growing these juicy and fragrant fruits. In some countries, the plant is cultivated to obtain spinning fibers from its leaves.
Pineapple - herbaceous land plant up to 75 cm tall, having a stem covered with prickles and narrow long succulent leaves. The accessory roots of this culture develop in the sinuses of its leaf plates and absorb moisture accumulating there. Over time, a peduncle is formed in the center of a fully formed leaf rosette, covered with a huge variety of bisexual flowers. After a three-week flowering at the site of the peduncle, large yellowish-brown seed heads appear, resembling a coniferous cone. In the upper part of the fruit, a kind of “tuft” of juicy vegetative leaves is formed. The skin of a ripe pineapple has a uniform brownish-golden hue and a light, pleasant aroma, and the vegetative leaves of a ripe fruit are easily pulled out from the “tuft” located at its top. Excessively strong sweet smell, the presence of brown, green or light spots on the peel, as well as the darkening of the veins between the scales of the seed fruit indicate that the fruit did not have time to ripen or began to rot.
Pineapple seedlings are a valuable food. The sour-sweet, fragrant flesh of the fruit of this plant is eaten raw (raw) and in the form of canned food, dried, used in the confectionery industry to make jams, sweets, jam and candied fruits. Along with this, pineapple fruits, rich in vitamins, useful macro- and microelements, are actively used in medicine to combat the most diverse pathologies.
