Trees seem completely lifeless to us in winter. And meanwhile, even in winter, in the most severe frosts, life does not completely leave the plants. At this time, they only rest, accumulate strength, in order to throw off the winter shackles with the onset of spring. “What we call the dream of nature,” wrote S. Pokrovsky, “is only a special form of life, full of deep meaning and significance.” This form of life of plant organisms is called a state of rest.
In a state of deep rest winter time years, the metabolism of trees and shrubs is sharply inhibited and visible growth stops. However, this does not mean that all life processes have completely stopped in it. Some of them also go during winter dormancy. For example, starch turns into sugars and fats, sugars are consumed during respiration (although its intensity is 200-400 times less than in summer. Growth processes also occur at this time, only they do not manifest themselves outwardly. The state of rest is a period of especially intense activity of the so-called educational tissue, or meristem, from which new cells and tissues arise.
Grape
In gardens and home gardens, you can choose a warmer place for planting grapes, for example, on the sunny side of the house, garden pavilion, veranda. It is recommended to plant grapes along the border of the site. The vines formed in one line will not take up much space and at the same time will be well lit from all sides. Near buildings, grapes should be placed so that water flowing from the roofs does not fall on it. On level ground it is necessary to make ridges with good stock through waterways. Some gardeners, according to the experience of their colleagues from western regions countries are digging deep planting holes and filling them with organic manure and fertilized soil. Pits dug in waterproof clay are a kind of closed vessel that fills with water during the monsoon rains. In fertile land root system grapes develop well at first, but as soon as waterlogging begins, it suffocates. Deep pits can play a positive role in soils where good natural drainage is provided, the subsoil is permeable, or reclamation artificial drainage is possible. planting grapes
You can quickly restore an obsolete grape bush by layering (“katavlak”). To this end, healthy vines of a neighboring bush are placed in grooves dug to the place where the dead bush used to grow, and sprinkled with earth. The top is brought to the surface, from which a new bush then grows. Lignified vines are laid on layering in spring, and green ones in July. They are not separated from the mother bush for two to three years. Frozen or very old bush can be restored by short pruning to healthy above-ground parts or pruning to the "black head" of the underground trunk. In the latter case, the underground trunk is freed from the ground and completely cut down. Not far from the surface, new shoots grow from dormant buds, due to which a new bush is formed. Grape bushes that have been neglected and severely damaged by frost are restored due to stronger fatty shoots formed in the lower part. old wood, and removal of loose sleeves. But before removing the sleeve, they form a replacement for it. Grape care
A gardener starting to grow grapes should study the structure well. vine and biology of this most interesting plant. Grapes belong to liana (climbing) plants, it needs support. But it can creep along the ground and take root, as is observed in Amur grapes in a wild state. Roots and above-ground part stems grow rapidly, branch strongly and reach large sizes. V vivo without human intervention, a branched vine grows with many vines of various orders, which comes into fruition late and yields irregularly. In culture, grapes are formed, give the bushes a form that is convenient for care, providing high yield quality grapes. Grapevine Planting Lemongrass
Schisandra chinensis, or schizandra, has several names - lemon Tree, red grapes, gomisha (Japanese), cochinta, kojianta (Nanai), kolchita (Ulchi), usimtya (Udege), uchampu (Oroch). In terms of structure, systemic relationship, center of origin and distribution, Schisandra chinensis has nothing to do with the real citrus plant lemon, but all its organs (roots, shoots, leaves, flowers, berries) exude the aroma of lemon, hence the name Schisandra. A clinging or winding liana of lemongrass, along with Amur grapes, three types of actinidia are original plant Far Eastern taiga. Its fruits, like a real lemon, are too acidic for consumption in fresh, but they have medicinal properties, pleasant aroma, and this attracted a lot of attention to it. The taste of Schisandra chinensis berries improves somewhat after frost. Local hunters who consume such fruits claim that they relieve fatigue, invigorate the body and improve eyesight. In the consolidated Chinese pharmacopoeia, compiled back in 1596, it says: "Chinese lemongrass fruit has five tastes, classified in the first category of medicinal substances. The pulp of lemongrass is sour and sweet, the seeds are bitter-astringent, and in general the taste of the fruit is salty. Thus, It contains all five tastes. Grow lemongrass
Winter activity of birches, poplars, maples, ash trees...
Interesting and entertaining questions about nature continue on the much-loved site mnogo.ru, however, the interpretation of tutanetam is the same. Appears Let's talk about trees which cause a lot of controversy on the subject of: whether they grow or not grow in the winter.
The wording itself is not entirely correct for defining the life of these perennials. Because as long as the tree has not dried up, it lives, regardless of whether it is summer or winter on the street, in the yard, in the city or in the village. Those. if it lives, then it grows even in winter, although we do not observe this. Well, where can you find millimeters of crown growth on a 30-meter handsome poplar, for example.
But, there are still rhizomes that lead active life and in winter, maybe no less than in spring, because it is always necessary to extract strength for the trunk and branches, regardless of the weather. Therefore, this is another argument that they are growing.
How to answer the question about the winter growth of trees in order to pick up 5 bonuses?
- The answer from the quiz of the day on January 31 is no, because tree growth is halted in winter!
- Therefore, without further ado, choose this answer, although it is slightly not entirely correct ...
Let's read a little about trees.
To the question Do trees grow in winter? Why? given by the author Salmon the best answer is In plant organisms, periods of vegetation, intensive growth alternate with rest. In a state of deep rest, the metabolism of plants is sharply inhibited and visible growth stops.
However, this does not mean that all life processes have completely stopped in it. Some of them also go during winter dormancy. Growth processes are also taking place at this time, but this does not manifest itself outwardly.
The state of winter dormancy is a period of intense activity of the so-called educational tissue, or meristem, from which new cells and tissues arise.
Both in evergreen and deciduous plants at this time, the rudiments of leaves are laid in vegetative buds and flower elements in flower buds. Without this, the upcoming spring transition to active life would be simply impossible.
That is why for a large number of plants, and above all for all perennial forms, dormancy is an indispensable condition for further normal growth during the growing season.
The ability to sink into a state of rest, developed by plants in the course of evolution, is an important adaptation to the periodic onset of adverse external conditions.
This is once again confirmed by the fact that plants sometimes stop growing not only in winter, but also in summer. For example, during a drought, some of them shed their leaves and completely stop visible growth - just like in late autumn.
This phenomenon is called forced dormancy. In this condition forest trees and shrubs are at the very end of winter.
If in January - February you cut a birch branch in the forest, bring it into the room and put it in water, then the leaf buds will soon start to grow and sprout. However, if such a branch is cut in October or November, then it will not bloom for a very long time. At this time, the plant is in a state of deep dormancy, which even the most favorable conditions for growth cannot disturb.
Deep dormancy is a necessary phase of plant development, replacing the growing season.
The duration of the dormant period different trees and shrubs is different. For example, elderberry, honeysuckle, buckthorn, lilac, black currant have a short period of deep dormancy, it ends in October.
If grown in greenhouses, they behave like evergreens: the buds that should have sprouted next spring, bloom in November, long before the plant sheds its old leaves.
Perhaps these plants were indeed evergreen in the past. In the process of evolution, as the climate cooled, they adapted to new conditions and began to shed their leaves for the winter, but retained the ability to go through a dormant period at a relatively high temperature.
Much longer - until January - this condition lasts in warty birch, hawthorn, white poplar.
And the longest “rest” is at small-leaved linden, Tatar maple, Siberian spruce, and Scotch pine. Wintering lime buds, for example, are unable to germinate for almost half a year. In oak, beech, ash, the buds are in a dormant state until the end of April.
Answer from stick through[guru]
They don't grow. Too little light, no photosynthesis.
Answer from I-beam[guru]
nature sleeps in winter. because there is little sun
Answer from Dmitry Savenkov[master]
yes, but noticeably slower than in summer, since the tree still lives and chemical processes are still taking place in it, and photosynthesis is not as rapid as in summer, but it still exists !!
And we continue to publish answers to popular winter quizzes. And today we are considering interest Ask - Do trees grow in winter?
Correct answer number 1 - No, their growth stops in winter
Trees do not grow in winter. It's just that plants that grow in temperature zones with seasonal changes must be able to go into a dormant state for a period when environmental conditions, such as short days and lower temperatures, become unfavorable for growth. Many trees and bushes go dormant, shed their leaves in autumn, stopping photosynthesis and minimizing moisture loss. From autumn, with its shortening days and cold nights, plants begin the process of fighting for survival. which is called "hardening". Since there are no conditions for growth in autumn, the plant spends its energy on accumulating more nutrition in the cells. At the same time, the accumulated water from the cells is displaced into the surrounding space, where, in case of freezing, it will not cause much harm.
The trees under the snow seem lifeless, but this is not entirely true. Even the plants are alive. In winter, they rest, accumulating energy, with the advent of warm days, they bloom again, which pleases the world. Many are interested in whether Their growth has some features during this period.
What affects plant growth?
V autumn period trees may enter a state of dormancy. The preparation is gradual. In autumn, the leaves begin to fall, and when the cold sets in, they are completely gone. The warm autumn season with slight cold weather allows you to survive the harsh period. Usually preparation lasts at 0-5 degrees. If such a period lasts several weeks, then the plant will be easier to tolerate frost. It will be easier for him to survive even severe frosts.
Trees can withstand up to -50 degrees. The seedlings that appeared in the plant are adapted to the local climate. With them there will be no problems regarding adaptation. Because of this, you will not need to spend a lot of time on care.
winter period
What happens to trees in winter? They are in a state of rest. There is a slowdown in the metabolism in the trunks, and visible growth stops. But the processes of vital activity occur in the same way as in another period.
During this period, mutual transformations of substances are carried out, but this is not carried out as intensively as in summer. How to understand if a tree grows in winter? There is plant growth in winter, but it is not visible from external signs. During the cold period, an educational tissue appears, from which new cells are formed. Hardwoods will lay the rudiments of leaflets.
Without these processes, the plant cannot prepare for spring. In winter, peace comes to the trees, this is considered necessary condition for normal growth. This ability was obtained during a long evolution, which became necessary in adapting to negative conditions. It is this condition of trees in winter that is considered normal. Similar phenomena occur in the summer. For example, during a severe drought, plants shed their leaves and hardly grow.
winter calm
The transition to the winter state is evidenced by the reduction of long daylight hours. This is due to the leaves and buds. When the day becomes short, the ratio between the components that are necessary for the processes of metabolism and growth changes in plants. According to such processes, it is clear whether a tree grows in winter? Plants are preparing to slow down many processes.
The state of dormancy lasts until the end of winter. But at the same time there is a preparation for awakening. If at the end of February you cut a birch twig and put it in water in warm room, then after some time there will be swelling of the kidneys, and then shoots will appear. But if this is done with the onset of winter, then the plant will not bloom, as it is ready for rest.
In winter, depends on its type. Each plant has its own duration of the winter period. In lilacs, this period is short, it ends by November. Poplar and birch winter until January. Maple, linden, pine, spruce dormancy lasts about 4-6 months. After that, the life processes of trees and shrubs are restored, and then their growth occurs intensively. But the roots of trees grow in winter, which is laid down by nature.
winter planting
In winter, plants are often planted. Large trees and large shrubs are best suited for this. Then it will turn out to create a beautiful landscape on the site, and you do not need to wait for the trees to grow.
What is the peculiarity of winter plant transplantation? Trees can be replanted without harming them. Winter plantings are considered irreplaceable if the plant is mature. And planting young trees begins in the spring, as this is the most favorable time for them.
Snow and ice protection
If icing is planned in the winter, consider plant protection. Ice that appears on the branches breaks them. Protection is especially required for fruit plants. For this, a solution is prepared based on 0.5 kg of lime and 1.5 kg of sand. The components are filled with water (10 l). Trees should be sprayed with the composition a few days before frost. After the formation of ice, it only needs to be shaken off the branches.
Snow can also damage plants as it breaks them. This applies to the columnar forms of trees - to juniper, thuja, conifers. Front winter period the branches are tied so that they become closer to the trunk. In this form, they will not be afraid of snowfalls. It also protects against sunburn.
Small trees can freeze from frost. To protect them, sawdust, peat or soil from other areas are used. They are scattered around. You can think of protection from the wind. This allows you to save them so that in the spring they can again delight with their beauty. And in some trees, protection is needed to maintain fruitfulness.
