Trees in winter seem to us completely lifeless. Meanwhile, even in winter, in the most bitter 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 a 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 in winter time years, the metabolism of trees and shrubs is sharply inhibited and visible growth stops. However, this does not mean that all vital processes have completely stopped in it. Some of them go on 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 take place at this time, but they do not manifest themselves in any way outwardly. The state of rest is a period of especially intense the activity of the so-called educational tissue, or meristem, from which new cells and tissues arise.
Grapes
In gardens and in private plots, 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 plot. 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 must 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 drain due to drainage grooves. Some gardeners, according to the experience of their colleagues from western regions countries dig deep planting holes and fill them with organic fertilizers and fertilized soil. Pits dug in waterproof clay are a kind of closed vessel that fills with water during monsoon rains. In a 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 there is good natural drainage, permeable subsoil, or reclamation artificial drainage is possible. Planting grapes
It is possible to quickly restore an obsolete grape bush by the method of layering ("katavlak"). For this purpose, healthy vines of a neighboring bush are laid in grooves dug to the place where the dead bush used to grow, and sprinkled with earth. A top is brought to the surface, from which a new bush then grows. Lignified vines are laid on layering in spring, and green vines 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 trimming to healthy aboveground parts or by trimming to the “black head” of an underground stem. In the latter case, the underground bole is freed from the ground and cut down entirely. Not far from the surface, new shoots grow from dormant buds, due to which a new bush is formed. Grape bushes neglected and severely damaged by frost are restored due to stronger fatty shoots formed in the lower part old wood, and removing loose sleeves. But before removing the sleeve, a replacement is formed. Grape care
A gardener who starts growing grapes needs to study the structure well vine and the biology of this interesting plant. Grapes are lianas (climbing) plants, they need support. But it can creep along the ground and take root, as is observed in wild Amur grapes. Roots and aerial part the stems grow quickly, branch strongly and reach large sizes. IN natural conditions without human intervention, a branched bush of grapes grows with many vines of various orders, which comes into fruiting late and yields irregularly. In culture, the grapes are formed, give the bushes an easy-care shape that provides high yield high-quality bunches. Grape Vine Planting Schisandra
Chinese schisandra, or schizandra, has several names - lemon Tree, red grapes, gomisha (Japanese), cochinta, kozyanta (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 a lemon scent, hence the name Schizandra. The lemongrass vine, clinging or wrapping around the support, along with Amur grapes, three types of actinidia are original plant Far Eastern taiga. Its fruits, like real lemon, are too sour for consumption in freshbut they have medicinal properties, a pleasant aroma, and this attracted a lot of attention to him. The taste of Schisandra chinensis is somewhat improved after frost. Local hunters who consume such fruits claim that they relieve fatigue, give the body vigor and improve vision. The consolidated Chinese Pharmacopoeia, compiled back in 1596, says: "The fruit of the Chinese magnolia vine has five flavors and is classified as the first category of medicinal substances. The pulp of schisandra is sour and sweet, the seeds are bitter-astringent, and the overall taste of the fruit is salty. it has 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. It appears the conversation will be about trees,which cause a lot of controversy about: do they grow or do not grow in winter.
The wording itself is not entirely correct for determining the life of these perennial plants... Because until the tree is dry, it lives, regardless of whether it is summer or winter on the street, in the yard, city or 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, it can be no less than in spring, because you must always get strength for the trunk and branches, regardless of the weather. Therefore, this is another reason that they are growing.
How to answer the question about winter tree growth in order to pick up 5 bonuses?
- The answer from the quiz of the day from January 31st is no, because tree growth is suspended 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 dormancy, the metabolism of plants is sharply inhibited and visible growth stops.
However, this does not mean that all vital processes have completely stopped in it. Some of them go on during winter dormancy. Growth processes are also taking place at this time, only 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.
In both evergreens and deciduous plants, at this time, the rudiments of leaves are laid in vegetative buds and elements of flowers 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 a prerequisite for further normal growth during the growing season.
The ability to plunge into a state of dormancy, developed by plants in the course of evolution, is an important adaptation to the periodic onset of unfavorable 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, in a drought, some of them shed their leaves and completely stop visible growth - just like in late autumn.
This phenomenon is called forced rest. In this condition forest trees and shrubs are found 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 the water, then the leaf buds will soon start growing and give shoots. 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 rest period in different trees and shrubs are different. For example, in elderberry, honeysuckle, buckthorn, lilac, black currant - the period of deep rest is short, it ends in October.
If grown in greenhouses, they behave like evergreens: buds that should have sprouted next spring bloom in November, long before the plant sheds old leaves.
Perhaps these plants were indeed evergreen in the past. In the process of evolution, as the climate became colder, they adapted to new conditions and began to shed their leaves for the winter, but retained the ability to pass a dormant period at a relatively high temperature.
Much longer - until January - this state lasts for warty birch, hawthorn, white poplar.
And the longest "rest" - in the small-leaved linden, Tatar maple, Siberian spruce, Scots pine. Hibernating linden buds, for example, are unable to germinate for almost six months. Oak, beech, ash buds are dormant until the end of April.
Answer from Push through[guru]
Do not grow. Little light, no photosynthesis.
Answer from I-beam[guru]
in winter, nature sleeps. because there is little sun
Answer from Dmitry Savenkov[master]
yes, but more noticeably slower than in summer, since the tree still lives and chemical processes still take place in it, and although photosynthesis is not as violent as in summer, 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?
The correct answer is number 1 - No, in winter their growth stops.
Trees do not grow in winter. Plants that grow in seasonally variable temperature zones simply need to be able to go dormant during periods when environmental conditions, such as short days and cold temperatures, become unfavorable for growth. Many trees and bushes become dormant, shed their leaves in autumn, stopping photosynthesis and minimizing moisture loss. In autumn, with its shortening days and cold nights, plants begin to struggle for survival. which is called “hardening”. Since there are no conditions for growth in autumn, the plant expends its energy to accumulate more food in the cells. In this case, the accumulated water from the cells is displaced into the surrounding space, where, in the event of freezing, it will not bring much harm.
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 arrival 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?
IN autumn period trees may begin to dormant. The preparation takes place gradually. In autumn, leaves begin to fall off, and when the cold comes, they are not at all. The warm autumn season with a little cold allows you to survive the harsh period. Usually preparation takes place at 0-5 degrees. If this 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 have appeared in the plant are adapted to the local climate. There will be no problems with them regarding adaptation. Because of this, you will not need to spend a lot of time on leaving.
Winter period
What happens to trees in winter? They gain a state of calm. Inhibition of metabolism in the trunks occurs, and the visible growth stops. But life processes 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 do you know if a tree grows in winter? There is plant growth in winter, but this is not visible by external signs. During the cold period, educational tissue appears, from which new cells are formed. Hardwoods will have leaf buds.
Without these processes, the plant cannot prepare for spring. In winter, there is peace for the trees, this is considered necessary condition for normal growth. This ability was obtained during a long evolution, which became necessary for adaptation to negative conditions. It is this state of trees in winter that is considered normal. Similar phenomena occur in the summer. For example, in severe drought, the plants shed their foliage and hardly grow.
Winter rest
The transition to the winter state is evidenced by the reduction in long daylight hours. This is due to the leaves and buds. When the day becomes short, in plants the ratio between the components that are necessary for the processes of metabolism and growth changes. From such processes, it is clear whether the tree grows in winter? Plants prepare themselves to slow down many processes.
The dormant state lasts until the end of winter. But at the same time there is a preparation for awakening. If at the end of February, cut off a birch twig and put it in water in warm room, then after some time there will be swelling of the buds, and then shoots will appear. But if this is done with the onset of winter, then there will be no blooming of the plant, since it is ready for rest.
In winter, it depends on its type. Each plant has its own duration of the winter period. For 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 this, the vital processes of trees and shrubs are restored, and then their growth occurs intensively. But the roots of trees grow in winter, which is laid by nature.
Winter landing
Plants are often planted in winter. Large trees and shrubs of large sizes are better 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 special about winter plant transplantation? Trees can be replanted without damaging them. Winter landings are considered indispensable if the plant is adult. And the planting of young trees begins in the spring, as this is the most favorable time for them.
Snow and ice protection
If, according to the forecast, icing is planned in winter, it is necessary to consider plant protection. The 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 poured with water (10 l). The 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 twigs 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 sprinkled around. You can come up with wind protection. This allows them to be preserved so that in the spring they can again delight with their beauty. And in some trees, protection is needed to preserve fruitfulness.
