Common hop, Humulus lupulus. Description, illustrations of the plant

Common hop, Humulus lupulus L. Botanical description, history of origin, nutritional value, cultivation, use in cooking, medicine, industry

Hops ordinary

Perennial herbaceous liana with a well-developed rhizome, from which stems up to 5 m long, with hooked thorns extend. The leaves are hard, ovate, three-five-lobed, large-serrated, long-petiolate. The flowers are small, greenish-white; female ones form short spikes. The fruit is nuts, collected in brown infructescences (cones). Blooms in July.

Hops originate from Asia. In the wild, it is distributed in all parts of the world with a temperate and humid climate. It grows among shrubs, in ravines, on river cliffs, along roadsides, forming fences, tangled thickets.

Hops were consumed by the ancient Romans. In culture, he became known from the VIII century in Western Europe, and from the X - in Rus'. Currently, hops are cultivated on industrial plantations in many countries in order to obtain cones. They are harvested when they begin to ripen, that is, they acquire a greenish-yellow color, and spring when compressed. It is not recommended to collect cones with strongly protruding scales: they contain many seeds and few lupulin glands.

The cones are plucked by hand and immediately dried in the open air, spreading out in a thin layer in the shade. After drying, they are knocked out in sieves to isolate the lupulin glands. Dried cones at a temperature not exceeding 40 ° C are fumigated with sulfur to protect them from pests, and then pressed.

The presence of nuts in hop cones reduces the quality of hops, so only female specimens are planted on plantations, and in order to prevent pollination and the formation of nuts, male specimens of wild-growing hops are destroyed within a radius of 2 km.

Hop cones are rich in lupulin, a bitter resinous aromatic substance. Lupulin contains bitter hop acid, resinous and tannins, vitamins P, C, and B1, a special kind of camphor, essential oil, some valeric acid, and a number of other compounds.

Hops is used as a medicinal and food plant. In folk medicine, hop infusion is known as a sedative and anticonvulsant for diseases of the nervous system and as an analgesic for gastritis, peptic ulcer, cholecystitis. As a means of improving appetite, hops are recommended for people weakened by severe chronic diseases. A decoction of unripe fruits is taken for thrombophlebitis and as a diuretic, infusion - for malaria, pulmonary tuberculosis, for diseases of the joints, as an antihelminthic and antiscorbutic agent.

A decoction of hop roots is used for jaundice and migraine, externally - for neuralgia, sciatica, skin diseases. Hop leaves are used to strengthen hair roots in case of early baldness, acne.

Hop cones are part of the soothing tea. The essential oil is used to prepare the drug valocordin, and the dry extract of hop cones is used to prepare the drug valosedan. Since hops contain toxic substances, treatment with its preparations is carried out under the supervision of a physician.

Hops are not bred specifically as a vegetable plant. But in the spring, before the leaves open, its young shoots can be used raw, like a salad, or cooked, like asparagus or cauliflower. Shchi is cooked from young leaves.

The main use of hop cones is in the brewing industry. They give beer bitterness, aroma and the ability to persist for a long time without sour. The cones collected at the beginning of maturation have long been used in bakery for the preparation of liquid yeast. Hops are a good honey plant.

Common hop, Humulus lupulus. Description of the plant, area, cultivation, application

Hops ordinary

A perennial plant from the hemp family with curly ribbed stems that die off for the winter (grows in spring from rhizome buds), over 10 m long.

The stem is tetrahedral, covered with short hooked spines along the ribs. Leaves on long, thin, tenaciously rough petioles with large lanceolate, mostly fused stipules; they are dark green above, lighter below, rough, seated with golden yellow glands, palmately incised into 3-5 large-sharply serrate lobes pointed at the edges. Only the upper leaves are sometimes entire.

The root system consists of a main rhizome (uterus) thickened up to 12 cm, from which 8-10 thick main roots extend (deep into the soil up to 5 m), branched into thinner roots and a dense network of thin roots.

Flowers small, dioecious. Staminate (male) flowers are greenish-yellowish, on short pedicels, collected in rare axillary paniculate inflorescences.

Pistillate (female) flowers in single heads with large covering scales, in the axils of which 2 flowers sit.

Covering scales increase greatly when ripe and give the inflorescence a resemblance to a cone. The scales are covered with golden yellow glands.

The fruit is a whitish-gray, rounded, slightly compressed one-seeded nutlet from the sides. The glands contain lupulin - a powder of light yellow color.

It consists of: essential oil, organic acids, yellow pigment, resinous and bitter, fatty and tannins, wax, etc. The leaves contain ascorbic acid. Blooms from June to mid-August.

Hop culture is distributed mainly in European countries, Japan, USA, Australia.

Only pistil (female) plants are bred. If a male appears near the hop plant, then it is destroyed in order to prevent pollination and the development of the seed-fruit, which would lead to the depreciation of the hop. The plant is cultivated in specially equipped fields with a system of poles with stretched cables and wire, along which this vine rises up, reaching a height of ten meters.

Hop is a perennial crop, but only its root system hibernates, from which new shoots develop every year. Their segments can propagate the plant vegetatively. In late summer, the hop cone ripens, covered with greenish-yellow glossy glands full of resinous yellow lupulin.

In addition to lupulin, the cones also contain hop resins, which are a mixture of phenols, resin acids and neutral resins.

The quantitative content of phenols and resin acids determines the quality of hop cones. The content of these substances varies depending on the hop variety and cultivation conditions, both climatic and soil, as well as the timing of harvesting.

The greatest amount of bitter substances is observed at the beginning of the browning of the cones.

Cones are harvested by hand or mechanically at the beginning of ripening, when they acquire a yellowish color. They are torn off with their stalks so that when dried they crumble less into separate scales.

Dry using an artificial heat source on grids. When dried, the buds should retain their greenish-yellow color. After drying, they are carefully placed in bags or boxes.

Initially, hops were classified only as medicinal plants. The first beer flavored with hops was brewed by the peoples who lived in Mesopotamia, between the Tigris and Euphrates. Currently, hop cones are used exclusively for brewing beer, they give it a bitter taste and protect it from spoilage.

The resins contained in the cones inhibit the development of bacteria that cause lactic acid fermentation. In addition to brewing, hops are also used in baking.

Hop cones are used as a sedative, anti-inflammatory, diuretic. It is prescribed as a decoction for neurosis, insomnia, gastritis, and as a remedy that reduces painful irritation of the bladder with cystitis.

Hops ordinary

Cultivation. Hop cuttings are cut from the rhizomes of 3-8-year-old plants, planted in the spring in well-fertilized and cultivated soil, in pits filled with humus, at a distance of 1 m from one another, between rows - 2,5 m.

In the autumn, manure (40 t/ha) and mineral fertilizers (up to 120 kg/ha) are applied on old hop stands and plowed between rows. In the spring, the underground parts of the stems, diseased and damaged roots are removed. With a length of plants 1-1,5 m, they are attached to wire trellises. During the summer, they loosen, feed, pinch the tops of the shoots, and remove stepchildren. Hops are harvested in late August - early September.

The cones are dried, fumigated with sulfur dioxide and pressed into bags.

The durability of hop plants is 20-30 years.

It grows everywhere in forests, in damp places, between shrubs, along river banks.

Perennial herbaceous climbing plant. Stems 5-6 m long (sometimes up to 18 m), 4-b-sided, hollow, rough along the edges of the ribs, densely planted with hooked spikes, which are attached to the trunks of trees, shrubs or spread along the ground. They die for the winter.

The leaves are large, on long, thin, rough petioles, rounded or ovate, heart-shaped at the base of the stems, green above, lighter below, rough, seated with golden yellow glands.

Blooms in June - July. Flowers female and male are located on different plants. Male flowers are small, on thin pedicels, collected in paniculate, drooping, hard-hairy inflorescences, 2-3 cm long, light green, odorless, located at the tops of branches and stems. Female flowers on short petioles, yellowish-green, each with a small membranous bract, sitting 2 in the axils of larger bracts, collected in ovoid apical or axillary, stalked spikelets.

After flowering, the bracts grow strongly, turn into seedlings - cones. On the inside of the bracts there are many sticky, yellow, shiny glands containing fragrant lupulin powder. Essential oil was found in it, which gives the plant a peculiar aroma, resinous, bitter, coloring substances, choline, etc.

The root is perennial, fleshy, deeply (up to 3 m) penetrates the soil, white inside, light brownish outside. Under the ground, perennial, long, horizontal shoots depart from it, in the nodes of which buds and adventitious roots develop.

Aerial stems grow from the buds every spring.

The fruit is a round, flattened, one-seeded nutlet, whitish-gray in color, ripens in August - September.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems.

Laser cooler for electronics 28.01.2013

A team of physicists led by Qihua Xiong of Nanyang Technological University in Singapore developed a new laser cooling technique by observing how nanostrips made from a different type of semiconductor, a compound of sulfur and cadmium, reacted to a laser beam.

Laser cooling systems are widely used in nuclear physics and in studies of the quantum properties of the microworld. Special laser traps and coolers make it possible to achieve temperatures close to absolute zero, which is practically impossible with other cooling methods. Despite the high development of this technology, it has not yet been adapted to work with semiconductor electronics based on silicon and gallium arsenide. As scientists explain, when irradiated with a laser, the atoms of the matter at which the device is directed absorb photons of its radiation. Under certain conditions, some of these photons are emitted back at a higher frequency, which consumes additional energy extracted from the thermal vibrations of atoms. Due to this, laser irradiation cools matter, rather than heats it up. This effect, the so-called anti-Stokes luminescence, is widely used in systems for laser cooling of atoms.

Xiong and colleagues found that anti-Stokes luminescence occurs in cadmium sulfide strips with a specially selected thickness and structure. Trying to achieve maximum cooling, scientists went through several options for laser emitters until they settled on a conventional green laser with a wavelength of 514 nm. According to the researchers, the green laser was able to cool coiled cadmium sulfide strips by 40 degrees Celsius at room temperature. As the temperature of the material and the environment decreases, the cooling efficiency gradually decreases until it reaches a minimum at 93 degrees Celsius below zero.

As the researchers note, a similar cooling technique can be applied to silicon microchips after additional research. Xiong and his colleagues believe that such laser "coolers" can be built into miniature electronic devices, due to the low power consumption and compactness of modern lasers.
