Why does the earth in a flower pot stink. Why do flowers smell. Signs of lack of water
Flowers are a wonderful creation of nature, in addition to their pleasant appearance, they have their own and unique aroma. With the help of smells, flowers attract insects for pollination, helping them to subsequently produce seeds. The fragrance can also serve as a warning to insects and animals. Few people wonder why flowers smell. The fragrance of each flower originates inside the buds and spreads around due to sunlight - when the flower opens. In other words, the smell comes from the essential oils inside the flower.
The process of creating a smell is actually very simple: the evaporation of oil from exposure to temperature. A lot of flowers smell really nice, drawing attention not only by their appearance, but also by the creation of fragrance in the air.
The smell of flowers conquered even such a baby
It is rather difficult to explain why the fragrance of flowers is felt at a distance, because the plant itself does not move. There is an opinion that it is insects that spread the fragrance of flowers over a long distance, since the flower itself cannot do this. However, this is not connected in any way, insects only collect pollen and carry nectar, which subsequently has a beneficial effect on plant reproduction.
In flowering plants, there are aroma molecules, which, under a certain external influence of temperatures, dissolve in the environment and are carried through the air due to diffusion processes. It is these molecules that give a person a unique sensation of the fragrant aroma of flowers. Molecules, reaching the nasal receptors, allow you to feel the whole gamut of shades of smell, enclosed in a single bouquet of floral aroma.
Shades of floral fragrances
The aroma of flowering plants depends almost entirely on which insect pollinates the flower. For example, if the main insect is a fly, then the smell will be rotting, actually cadaverous. Such flowers are predominantly predatory, luring flies with their smell, feed on them, for example
The most fetid flower in the world Amorphophallus titanic / Amorphophallus titanum
The appearance of a flower almost always directly corresponds to its aroma. But there are also pleasant-looking flowers that smell just disgusting. This mechanism is similar to an animal: a plant protects itself with a strong and unpleasant aroma, like some reptiles have an aggressive color, while being harmless. Likewise, flowers with a strong fragrance often do no harm.
It is worth noting that especially fragrant flowers usually have a white or yellow color. And brighter ones, on the contrary, have a mild aroma.
The smell is felt when combining essential oils into a single bouquet of aromas when exposed to sunlight. Flowers can be called nature spirits.
Why do flowers smell and what does it depend on? Summary »
- the smell is necessary to attract insects, as well as repel herbivores and pests;
- the aroma appears due to the essential oils contained in the plant;
- the smell of the plant depends on the color.
The fragrance of a flower is necessary for life, because without it there would be no pollination and reproduction.
The most fragrant flowers - top - 15
Flowering plants undoubtedly attract attention with their beauty, spectrum of shades and unique aromas. There are many different colors all over the world, each of which really smells different. There is even a kind of top 15, which contains the most fragrant flowers in the world.
plumeria
The most fragrant exotic flower - plumeria
This exotic flower grows in the tropics, preferring islands in the ocean and near the Caribbean Sea. The shades of these beautiful flowers are truly unique. There are a wide variety: from soft pink to passionate red, from faded white to bright yellow. Only the core of the golden color is unchanged.
Plumeria smells distinctly of the tropics - a juicy floral aroma with fruity inclusions, and releases its fragrance closer to dusk. And it is considered immortal, because the flower does not burn in a hot fire, and is also able to be reborn even from its leaves. But, despite the attractive external beauty and aroma, plumeria is poisonous. In the conditions of the Russian climate, it is grown as a houseplant.

Moreover, the aroma intensifies along with the temperature: the hotter, the stronger the flower smells.
Wisteria
Wisteria profusely flowering
Wisteria grows in southern latitudes, and blooms in clusters hanging like grapes. The petals are white-purple, and the sweet fragrance is said to be a harbinger of spring. Cultivated plant species are more adapted to the Russian climate, for example, Blue Moon wisteria can withstand fairly low temperatures in winter.

Grows in warm climates. Jasmine is known all over the world, its white flowers smell delicate and sweet. Essential oils based on this plant are widely used in cosmetology and aromatherapy. Dried flowers are even used to make jasmine tea.
The peculiarity of the flower is that the root system of the plant is poisonous, and the buds smell much stronger than flowers. And the aroma can be felt only after sunset.
In the Moscow region, mock orange or garden jasmine are successfully grown.
Narcissus
Bright yellow flowers attract attention. And the aroma of narcissus is incredibly strong. The sweet smell with bitterness literally intoxicates, because it is not for nothing that the flower bears the name of a narcissistic young man.
Mimosa

Rose
Musk rose grade "Guirlande d'Amour"
The list is completed by the queen of all flowers - a rose. Roses, as a rule, are incredibly beautiful and have an extensive range. Surprisingly, even the aroma of each species is different. But one thing is invariable - the sweet aroma of roses is always extraordinarily captivating.
And, of course, these are just the top lines. In the world there are an incalculable number of beautifully smelling flowers, which seem to be designed to please people.
The fragrance of flowers has a great influence on people. The aroma of rose bushes uplifts the mood, driving away sad thoughts and dispelling stress. Not to mention the fact that roses are certainly associated with love. The smell of jasmine has a beneficial effect on concentration and performance, and bergamot seems to encourage. And the heat of the summer months perfectly smooths out the aroma of snow-white magnolias. Thus, flowers are not only a wonderful decoration of the garden, but also saturate the air with their aromas.
Flowers are the embodiment of beauty, tenderness, fragility; each flower is unique, not like the others. Although everyone has their own preferences when choosing fragrances, you can hardly find a person who would not like the smells of fragrant flowers. It is difficult to find something more beautiful in the world. Why do flowers smell?
These gentle creations of nature smell thanks to essential oils, or rather, the ones they contain. phytoncides - special substances that are contained in the cells of the petals or in the perianth, and in some plants are produced by special glands. These volatile substances play an important role in plant life. First of all, they contribute to the flow of metabolic processes in plant organisms. When released, essential oils evaporate immediately, enveloping the plant in a fragrant cloud. This veil protects the plant from overheating during the day and from hypothermia at night.
The smell of flowers attracts various insects for pollination. Each species of flowering plant adapts to its pollinators. For example, flowers pollinated by moths and night mice open only at night and have a very strong smell.
Predatory plants use scent to lure prey. Essential oils prevent infection of plant organisms by harmful fungi and bacteria. The smell of some flowers repels herbivores and prevents them from being eaten. Therefore, livestock bypasses sharp-smelling grasses. Thus, the smell allows plants to win in the competitive struggle for existence.
It has been noted that plants with a light color of their flowers have the most fragrant odors. Most often, their petals are white or light yellow. And vice versa: plants with bright, variegated flowers have a less pronounced smell.
Since ancient times, people have discovered the unique properties of essential oils. Currently, they are widely used in medicine, aromatherapy, perfumery, for flavoring drinks and foods, in household chemicals, and also as solvents. For example, the aroma of bergamot fruit is an effective remedy for depression and difficult mental states. Everyone's favorite roses have similar properties. Jasmine, iris, violet, citrus fruits also increase vitality.
The fumes of some plants are poisonous, which must be taken into account when decorating the interior of the house. For this reason, it is not recommended to keep plants of the aroid family in the room: monstera, dieffenbachia, spathiphyllum (popularly called “female happiness”), etc. On the contrary, oils of geranium, chlorophytum, begonias, orchids purify the air and calm the nervous system.
Scientists have calculated that all the plants in the world release from 100 to 150 million tons of aromas into the atmosphere every year.
In addition to the pleasure of inhaling the aroma, “communication” with flowers also gives aesthetic pleasure. In Japan, for example, girls from an early age must be taught the art of making bouquets.
Flowers are the best gift for any girl or woman. When they give her a bouquet, they usually express their warm feelings with this, as if they say that she is just as beautiful. Many cultures even developed a language of flowers. A presented bouquet can tell a lot without words, depending on how many flowers it contains, what color and variety they are.
Stomach cancer is one of the most common oncopathologies, the main danger of which is that it is rarely detected in our early stages. The fact is that this disease often does not have pronounced symptoms at the beginning of development, and the majority of the population simply does not pay due attention to preventive examinations. Therefore, stomach cancer is detected in the vast majority of cases at 3-4 stages.
In this case, you should not rely on domestic medicine, which relies on somewhat outdated treatment methods with insufficiently high efficiency and serious side effects. Even the best oncologists are limited both by outdated diagnostic and treatment hardware and by available pharmacological agents.
Therefore, in case of detection of stomach cancer, you should not tempt fate - it is better to raise funds for treatment in Israel.
Simple statistics - about 80% of patients diagnosed with stomach cancer (in some clinics, this figure reaches 90%), treated in Israeli clinics, demonstrate a five-year survival rate. Even the most severe cancer patients oncologists in this small country significantly prolong life and improve its quality.
Posted in categoryStomach cancer is a dangerous oncological disease, the treatment of which has a rather severe effect on the body. Even if it is possible to do without a complete or partial resection of the stomach, chemotherapy and radiation affect almost all organs and systems of the human body. If there was a significant surgical intervention (removal of the stomach partially or completely), the rehabilitation period can be especially difficult.
In Israeli clinics for the rehabilitation of patients after treatment of stomach cancer, special attention is given. After all, it depends on this period whether the cancer will recede forever, or a relapse will occur. In addition, aggressive treatments can have long-term side effects, and quite serious ones. The rehabilitation period under the supervision of Israeli doctors also allows minimizing their influence.
How is rehabilitation after stomach cancer in Israeli clinics?
Since each case of the disease is unique, the rehabilitation strategy, like the therapy strategy, is developed individually for each patient.
Patients diagnosed with gastric cancer usually need help to restore appetite, as well as general strengthening of the body, which due to cancer often suffers from cachexia (exhaustion). In the case of surgical intervention, the elimination of pain syndrome is also required. Another important point is psychological rehabilitation.
Israeli clinics use the Fast Track rehabilitation technique. Its basis is intensive rehabilitation within the walls of a medical institution, which allows minimizing the time spent in the hospital walls. Therefore, the average rehabilitation course is only 10 to 14 days.

Stomach cancer is a severe and dangerous pathology of the digestive system, in which a special diet must be strictly observed. It is necessary to change approaches to nutrition immediately after the detection of the disease. But especially strict adherence to the diet will be required after surgery, especially if there has been a partial or complete resection.
Compliance with the diet is an important auxiliary factor on which the recovery of the patient depends. Failure to comply with the diet can significantly worsen the state of health.
Rules for eating with stomach cancer
In order to remove the load from the digestive system and stomach as much as possible, it is necessary:
- - observe the regimen of frequent meals in strictly metered small portions - from 5 to 6 times a day;
- - products must have a puree consistency: they must be wiped, ground or crushed in another way;
- - the time intervals between meals should be the same;
- - you can not eat excessively hot or, on the contrary, cold food - only warm;
- - dishes must be prepared right before consumption in the amount of one serving - food cannot be stored;
- - dishes must be boiled or steamed - all fried is strictly prohibited;
- - plant foods should prevail in the diet;
- - fatty foods are prohibited;
- - salt should be replaced with herbal seasonings.
Chemotherapy is one of the classic methods of treating oncopathologies, including stomach cancer. This technique is the use of cytostatic drugs. As a rule, it is included in the treatment protocol for gastric cancer as an adjunct to surgery, but can also be used as monotherapy.
Chemotherapy performed in Israeli clinics can significantly reduce the growth rate of neoplasia and the spread of cancer cells throughout the body. This technique can be used before surgery (in order to reduce the mass of the neoplasm), after surgery (to prevent recurrence by destroying the remaining cancer cells) or during surgery (HIPEC technique).
Types of chemotherapy in Israeli clinics
In Israeli clinics, systemic chemotherapy and HIPEC are most often used to treat gastric cancer.
Systemic chemotherapy is the treatment of a cancer patient by introducing cytostatics into the body according to a certain scheme. It can be done with oral medications, injections, pumps, or drips. Most often, chemotherapy is performed on an outpatient basis, in cycles repeated every few months (three cycles before surgery, three after). One cycle usually lasts about three weeks.
Oral medications (such as capicetabine) are taken by mouth as tablets on a schedule approved by your doctor. Intravenous infusions are carried out through cannulas, a PICC line implant, or a central catheter. Most often, both oral and intravenous administration of cytostatics are involved, since, as a rule, not one drug is prescribed, but a combination of them.

When to Water
Irrigation errors occur quite often. Many novice flower growers, having overestimated the necessary need of a plant for moisture, act with the slogan: "More, not less", while being surprised that they, nevertheless, do not grow well. But the plants themselves are the best way to tell us when they need watering. Our business consists only in the ability to notice it.
Soil sample by pressing the index finger so that it plunges into the soil to a depth of about 1 cm, you will feel whether it is still wet enough.
Watering should be done only when most of the moisture contained in the soil has been used up. But do not wait for typical signals to appear, indicating a lack of moisture. When the soil dries up so much that it moves away from the walls of the dishes, then, when watering, the water instantly pours out of the pot and practically does not have time to be absorbed by the soil and an insignificant part of it reaches the roots. To prevent this, try to check the soil for moisture as often as possible. The easiest way to do this is to test the potting soil with your finger. You should press with your index or thumb until it sinks into the soil to a depth of about one centimeter. If you feel that the soil is still quite wet under the dry top layer, do not rush to pick up a watering can.
You can also lift the pot when the size of the plant allows it, and estimate its weight. If there is little moisture in the soil, then the pot will be noticeably light. In this way, the water content of the entire soil can be checked, not just the surface layer. This method is particularly suitable for plastic pots due to their low weight. When it comes to clay pots, you should pay attention to their walls: their dark red color indicates sufficient moisture content in the soil. With dry soil, the walls of the pot become light yellow.
It is still possible to determine soil moisture using the so-called "tapping method", however, it requires some experience. To do this, take the pot in your hand and knock on it with a wooden stick, pencil or fingernail. If the soil in it is wet, then the sound will be rather deaf, if the ground is dry, it will be more sonorous.
There are no general rules for watering and each plant needs its own regime, but, simply, depending on the needs of specific plant species for moisture, watering by intensity can be divided into:
Abundant watering.
Plants are watered immediately after the earthen clod dries. Similar watering is required for most tropical plants with thin and delicate leaves (begonia, allocasia, heliotrope, fittonia), as well as some of the plants with leathery leaves (ficus, lemon, ivy, oleander)
Moderate watering.
Plants are watered one or two days after the earthen coma dries out. These include plants with fleshy or heavily pubescent stems and leaves (columnea, peperomia), with thick roots and rhizomes (dracaena, palms, aroids, aspidistra), as well as those with water-bearing tubers on the roots (chlorophytum, asparagus, arrowroot) and bulbous. For some plant species, light drying is a prerequisite during the dormant period, as it stimulates the laying and maturation of flower buds (clivia, zygocactus).
Rare watering.
Plants stay dry for days, weeks or even months. These include cacti and succulents, as well as deciduous tuberous and bulbous plants that need a dormant period (gloxinia, krinum, caladium, hippeastrum).
Signs of under or over watering
With excessive watering, the ends of the leaves turn brown with pronounced yellowing.
By a number of signs, it is quite easy to recognize when plants are clearly suffering from a lack of moisture. The soil dries up and moves away from the walls of the pot, leaves droop in tree-like plants, and in herbaceous plants, not only leaves, but even the trunk itself. Other signs can tell us that although the plant is watered fairly regularly, it still does not receive the amount of water it needs - the leaves fade, their tips and edges turn brown, the flowers and buds fall off.
When watering with cold water, yellowish-gray spots may appear on the leaves of Saintpaulia.
Excessive watering can also cause root rot, the consequences of which can be the saddest. When the roots rot, water stops flowing to the plant, as a result of which it behaves in the same way as with a lack of moisture. Therefore, if the plant has drooped, first of all it is necessary to check the soil moisture, and if it turns out to be damp, try to carefully remove the plant from the pot.
The easiest way to do this is by "shaking" it out of the pot, while turning it "upside down" and holding the pot with one hand and the ground with the other so that it does not crumble much. If the earth lump, nevertheless, does not simply separate from the pot, then you need to carefully tap the pot on the edge of the table. After removing the plant from the pot, carefully inspect its roots. They should be light or even white at the tips. If they are brown and smell of rot, then, in this case, it is necessary to cut off the affected areas and transplant the plant into fresh soil.

They are one of nature's greatest scented gifts, everyone loves to enjoy their fresh scent. You can give them as a gift, decorate an interior to add a delightful scent to your home, but why do flowers actually have such an attractive fragrance?
The smell of flowers is usually a complex mixture of low molecular weight substances, and is the most important factor in attracting pollinators. Although the flowers may be the same in color or shape, no two floral scents are the same. Thus, smell is a signal that directs pollinators to the flower. Individual floral scents attract certain pollinating insects. Flowers with fragrant and sweet scents are pollinated by bees and flies, while flowers with spicy and fruity scents attract beetles.
As with all life forms, it is the process that allows reproduction. Pollinators are animals and insects that, in contact with flowers, and then, moving from flower to flower, transfer pollen, so new plants appear. The intensity of the floral scent can be affected by temperature and light levels, and there are some types of flowers that can intensify at certain times of the day or night. Snapdragons, for example, are more fragrant during the day, when pollinating bees are more active. Fragrant tobacco is more fragrant at night, and attracts moths with its aroma.
As you can see, the fragrance becomes stronger after rain, when the air is humid, this is because the scent molecules are much easier to spread. one of the sweetest smelling flowers, the most popular fragrance, often used in products such as candles, perfumes, soaps, lotions, and creams. The scent of the lilac is often associated with spring, and the flower has a rather strong, sweet fragrance, although the degree of sweetness can vary depending on the type of lilac. known for their rather strong, fragrant aroma, a bouquet of such flowers will fill the room with a delightful aroma. However, if you are sensitive to smells, opt for other, less fragrant flowers.
Flowers decorate our home, plants with their wonderful aromas and variety of colors are used in landscape design and as a gift, as one of the ways to express love and respect. What could be better than a fragrant bouquet!
