cultivated plants


In nature, all plants are divided into wild and cultivated. Cultivated plants are those plants that humans grow. If a gardener transplants wild raspberries to his site, takes care of her and collects fruits, then such raspberries will be called cultivated. If clover grows in natural meadows, it is a wild grass. But it can also become cultural if it is sown and nurtured by a person. So it is with every plant.


Man cultivates plants for food, animal feed, medicine, industrial raw materials, or ornamental purposes.


Scientists say that man began to cultivate plants many thousands of years ago. Accumulating knowledge, he passed on his observations to the next generation, gradually improving the properties of plants, classifying them and creating new species. So, about 15 thousand years ago, the science of growing cultivated plants by humans appeared - plant growing.


Later, breeding arose - a science with the help of which new varieties of cultivated plants are created by selecting for signs of resistance to diseases and pests, frost and drought resistance, productivity, and taste of fruits. As a result of selection, many varieties of cultivated plants have been created. For example, there are about 2 thousand varieties of apples.


There are several types of classification of cultivated plants. Popular is the classification by industry: field: cereals (wheat, barley, oats); cereals (rice, millet, buckwheat); legumes (beans, soybeans, peas); oilseeds (sunflower, mustard); spinning (kenaf, fiber flax, cotton); fodder (Sudanese, clover); gourds (pumpkin, melon, watermelon)


Vegetables: root vegetables (carrots, beets) and tubers (potatoes); leafy (cabbage, arugula, spinach); stem (rhubarb, sorrel); fruit (cucumber, tomatoes); bulbous (garlic, onion); spicy aromatic (parsley, cilantro, dill);


Fruit and berry: pome (apple, quince, pear); stone fruit (cherry, cherry, apricot, peach, plum); nuts (hazelnuts, almonds, Walnut); citrus fruits (tangerine, lemon, orange); berry (raspberries, currants, strawberries, grapes); decorative (floriculture).


More than 400 species of cultivated plants originated from South Asia, from North and South America, Europe - about 200 species, from Africa - about 50.


Homeland of cultivated plants Central Europe - wheat, peas, beans and lentils, flax; Mediterranean - carrots, cabbage, beets, radishes, turnips, onions; India and Indochina - rice, citrus fruits, tea; South and Central America - corn, potatoes, tomato, pumpkin, beans and capsicum, tobacco, sweet potato, pineapple, peanut, cocoa; North America - sunflower; Africa - coffee, barley.


The migration of cultivated plants from continent to continent began especially actively during the period of the Great Geographical Discoveries (since the 15th century).

Cultivated plant - species, forms and varieties of plants cultivated by man to obtain: Cultivated plant - species, forms and varieties of plants cultivated by man to obtain: - food; - raw materials for industry; - feed; as well as for decorative purposes, etc. Cultivated plants have evolved from wild ancestors through hybridization and selection. Often the properties of cultivated plants are so changed in the course of selection that they are not able to live in natural communities. It is believed that about 2 "500 species are involved in culture. Breeding is the science of creating new and improving existing breeds of domestic animals and varieties of cultivated plants. At the same time, selection is also understood as the process of changing living organisms carried out by man for his needs. All Modern domestic animals and plant crops cultivated by man originated from wild ancestors.The result of the selection process is a variety, breed, strain.A plant variety, animal breed, strain of microorganisms is a set of organisms created by man in the process of selection and having certain hereditary properties.. The main task breeding - the creation of highly productive animal breeds, plant varieties and strains of microorganisms, the best way satisfying the nutritional and technical needs of man. An organism created artificially (crossing) is called a hybrid.

cultivated plants-

plants grown by humans for food, agricultural feed, medicines, industrial and other raw materials, and other purposes.


Classification of cultivated plants according to Kuptsov

  • 1. Cereal crops.

These are the three main cereal plants: rice, wheat, corn and secondary breads - barley, oats, rye, millet, sorghum.


  • 2. Starch plants : potatoes in countries temperate climate, sweet potato, yams, taro - in more southern areas.

  • 3. Pulses:

beans, peas, lentils.


  • 4. Sugar crops: sugar beet and sugar cane.

  • 5. Fibrous Plants: cotton, flax, hemp, jute, kenaf, which provide a person with clothing and technical fabrics.

  • 6. Fruit and berry crops : apple trees, pears, plums, etc.

  • 7. Spicy aromatic and tonic plants, without which the modern human diet is impossible.

  • 8. Industrial or industrial crops- sources of rubber, medicines, tannins, corks.

  • 9. Forage plants ,

on which modern animal husbandry is based.


  • 10. Oilseeds: mustard, peanuts, sunflower, etc.


Division according to branches of agriculture

Experts distinguish groups of cultivated plants according to the type of agricultural activity:

  • fruit growing,
  • vegetable growing,
  • field cultivation.

field varieties

  • This group of plants includes grain crops (cereals- rye, wheat, legumes- lentils, soybeans, peas, cereal varieties- millet, buckwheat, root vegetables (turnips, beets), tubers(potato), spinning(hemp, flax, cotton), oilseeds(mustard, peanuts, sunflower), fodder grasses(alfalfa, clover).

fruit varieties

  • This group includes crops that produce juicy fruits. They, in turn, are divided into stone fruits(apricot, plum, cherry) pome e (quince, pear, apple tree), berry(currant, strawberry, raspberry, strawberry). In the same group, in some cases, include citrus(orange, lemon) nut-bearing(hazelnut, almond, walnut). In fruit and berry, a subgroup is sometimes distinguished subtropical varieties. These include, in particular, medlar, pomegranate, figs. Crops such as wild rose, sea buckthorn and others are considered close to fruit and berry crops. vitamin-bearing.

vegetable varieties

  • Vegetable crops are herbaceous plants grown for heads, root crops, bulbs, leaves, fruits. Cultivated 120 species vegetable plants. The most common of them belong to 10 families: cruciferous - cabbage, swede, turnip, radish, radish, horseradish, watercress; umbrella - carrots, parsley, parsnips, celery, dill; pumpkin - cucumber, pumpkin, melon, watermelon; nightshade - tomato, pepper, eggplant, physalis; legumes - peas, beans, beans; lily - onion, garlic, asparagus; Compositae - lettuce, chicory, artichoke, tarragon; haze - beets, spinach; buckwheat - rhubarb, sorrel; cereals - corn.

"Varieties and Origins of Cultivated Plants". Human life without plants is impossible. Many plants used by man live in nature in a wild state. wild plant plants that live in nature in a "wild" state. The selection that humans have made is called artificial selection. Thus was the beginning of crop production. Weeds are a special group of plants. Many cultivated plants cultivated in all countries, on different continents. Thousands of seed samples were brought from the trips.
