Roses picked in the afternoon will wilt more easily than those picked in the morning, why?

In fact, the roses picked in the afternoon will be less likely to wither than those picked in the morning, because the roses picked in the afternoon are mainly weakly alkaline, and the pigment is relatively stable in the state of weak alkaline, which can last longer for the color of each petal, so the roses picked in the afternoon can maintain the color for a longer time. For people who love flowers, they are in a happy mood when they see beautiful and beautiful flowers, and they hope that the flowers will not wither and keep them for a longer time. However, it is difficult to keep the flowers from withering, and the only time to keep the flowers from withering is relatively late.

In our usual observations, we can see that the roses picked in the afternoon remain a little longer than the roses picked in the early morning.

This is because all species of plants do not survive long after they leave the rhizomes that provide them with nutrients, because plants need to undergo chemosynthesis and respiration if they want to sustain their lives.

Just like humans, not only do they need to breathe all the time, but they also need to eat food to balance the nutrients in their bodies. So it is only in the whole state that the rose is able to photosynthesize.

To give the body ** organic matter, but also to decompose organic matter while respiring to ensure normal nutrition**.

Although the roses are bright in color, they are not exposed to sunlight after a night of breathing.

The organic matter in the rose has been decomposed by irradiation. Even so, it must continue to breathe to maintain the nutrients it needs for vital activities. So the roses that are picked in the morning are always respiring, and the carbon dioxide in its cells.

The concentration is very high, and the carbon dioxide in its body will not disappear easily without photosynthesis. At this time, the roses are in a weakly acidic environment, because the pigment in the weakly acidic environment is unstable, so the roses are easy to wither.

The fact is that roses picked in the afternoon are less likely to wilt, because the roses picked in the afternoon are alkaline and easier to retain the pigment of the flowers.

Roses in the afternoon are generally exposed to more sunlight, and long-term ultraviolet exposure will cause the roses to wither, so the roses in the morning will be more vibrant.

Because the roses picked in the afternoon have been irradiated by the sun's rays and have lost a lot of moisture, the moisture of the roses in the morning has not been lost, because the dew in the morning also gives the roses moisture.

For Aihua people, whether they buy flowers themselves or receive flowers from others, we always hope that it will never wither.

Among the many flowers, roses have a special meaning and are the most popular flowers. So what do we do to make it less susceptible to withering?

When the roses are not plucked, they are connected to the rhizomes and leaves, and they are part of the plant, and photosynthesis and respiration are necessary for the plant to maintain normal survival activities. As long as the plant is alive, respiration is always there, and photosynthesis requires the participation of sunlight, so in the absence of light, plants cannot photosynthesize, generally speaking, the effect of photosynthesis is stronger than respiration, so the plant can maintain growth.

The roses picked in the evening, due to the exposure to sunlight throughout the day, the whole plant is dominated by photosynthetic effects, absorbing CO2 in the air and water in the soil, and synthesizing organic matter under photosynthesis. At this time, the CO2 in the plant is used, so the concentration is very low, and the plant is neutral or weakly alkaline. The roses picked in the morning, because there is no sunlight all night, the whole plant is mainly breathed, and the respiration decomposes the organic matter in the body into CO2 and water, and obtains energy to maintain survival activities.

After a night of respiration, the CO2 concentration in the plant is relatively high, and the whole plant is almost slightly acidic.

This is why the trumpet flowers are reddish in the morning and blue in the evening. The state of weak acidity is more conducive to the decay of flowers, and pigments such as anthocyanins are also destroyed more quickly under acidity, so morning roses are more likely to wilt.

Early morning roses have other substances that interfere, so the retention time is short.

Bouquets of roses picked in the afternoon contain more moisture than those picked in the morning, so they will last longer than those picked in the morning.

The roses in the early morning have dew, but in the afternoon they don't, so it's better to save some.

In the afternoon, the pores are closed and there is little dehydration, and in the morning the opposite is true.

The afternoon is not as strong as the early morning sun, and the ultraviolet rays are weaker.

Roses picked in the morning are fresher than those picked in the afternoon.

The roses in the afternoon will not bloom without sunlight.

In the afternoon, roses receive less sunlight.

I think it's caused by the respiration of plants.

Roses are not easy to wither when picked in the afternoon.

What we need to know is that plants will carry out photosynthesis and respiration, and photosynthesis refers to the process of plants producing organic matter and oxygen by absorbing CO2 and H2O under light conditions. The respiration of plants refers to the consumption of organic matter, water, oxygen to produce water, CO2, plants carry out photosynthesis and respiration at the same time during the day, but generally speaking, the effect of photosynthesis is stronger than respiration, and roses only respire after dark.

The roses picked in the evening have undergone full photosynthesis throughout the day, producing a large amount of organic matter that can be used for respiration at night and providing raw materials for consumption, which is extremely active. At this time, the CO2 in the plant is used for photosynthesis, the CO2 concentration is low, the plant is neutral or weakly alkaline, and the roses picked are more durable than the roses picked in the morning.

Introduction of roses

Roses prefer sunny, hardy, drought-tolerant, well-drained, loose and fertile loam or light loam, grow poorly in clay loam soils, and do not flower well. It should be planted in a well-ventilated place far away from the wall to prevent sunlight reflection, burn the flower buds, and affect flowering. Roses are masculine plants, and when the sun is sufficient, the flowers are strong in color and fragrance.

During the growing season, if the sun shines for less than 8 hours, it will not bloom for a long time. The requirements for air humidity are not very strict, and rust and powdery mildew occur when the temperature is low and the humidity is high.

The flowering season requires a certain humidity in the air, and the oil yield decreases when the temperature is high and dry. Roses do not have strict requirements for the pH of the soil, and can grow normally in slightly acidic to slightly alkaline soils. Areas with snow cover in winter can tolerate low temperatures of -38 to -40, and areas without snow cover can tolerate low temperatures of -25 to -30, but not dry winds in early spring.

In areas where the soil has not thawed and the ground is windy, shoots tend to be blown dry by the wind.

Roses symbolize love, so they will be loved by our young people. We all give our boyfriend and girlfriend a bright rose on Valentine's Day.

However, picking a rose is also particular. For example, at different times of the day, our roses are easy to wither in the morning, but not easy to wilt in the afternoon. Why is that?

The reason is that the roses picked in the afternoon are mainly weakly alkaline, and their pigments are relatively stable in the state of weak alkaline, which can last the color of each petal for a longer time, so the roses picked in the afternoon can maintain the color for a longer time.

Remember to pick roses in the afternoon, so that the roses will be brighter, more colorful, and more beautiful!

The roses picked in the afternoon are neutral or weakly alkaline because they have been exposed to the sun for nearly the whole day, and the CO2 in the plant is used. The CO2 concentration of roses picked in the morning was relatively high, and the whole plant was almost weakly acidic. The state of weak acidity is more conducive to the decay of flowers, and pigments such as anthocyanins are also destroyed more quickly under acidity, so morning roses are more likely to wilt.

The roses picked in the evening, due to the exposure to the sun throughout the day, the whole plant is dominated by photosynthesis effect, absorbing CO2 in the air, and then combining with water and sunlight to synthesize organic matter, and the CO2 in the plant is used, so the concentration is very low, and the plant is neutral or weakly alkaline.

Because the roses picked in the afternoon have experienced the light throughout the day, the CO2 concentration in the body is very low, and in this state, the roses are less likely to spoil, and the anthocyanins are not easily damaged.

The wilting of flowers has nothing to do with the time of picking, modern technology can make beautiful flowers bloom for a longer time.

Experts believe that the time of picking does not affect the storage of roses, and whether roses are prone to wilting has a lot to do with the way roses are stored. Changing the water infrequently, placing it in a warmer place, and putting it together with fruit will speed up the decay of roses. Therefore, no matter what time the flowers are picked, they must be stored in a reasonable way and carefully cared for, so that the beauty can be retained for a longer time.

With the development of science and technology, methods of preserving flowers are constantly being discovered. For example, a nutrient solution is added to the water to provide the necessary nutrients to the flowers; Drugs are put in to slow down the wilting of flowers; Preservation through refrigerator refrigeration or cold storage, etc. Therefore, even if the flowers are transported over long distances, as long as they are stored properly, they can be kept as long as possible.

Because the morning rose absorbs the carbon dioxide of the night.

Because the roses in the morning absorb the carbon dioxide overnight, the roses picked in the afternoon lose a lot of water.

This is because this is the time when the carbon dioxide concentration in roses is at its lowest.

The roses picked in the afternoon lose a lot of moisture, and the roses in the afternoon have no moisture.

This should be related to the growth habits of roses.

The roses in the afternoon are already out of moisture.

Because the roses picked in the afternoon have lost a lot of moisture.

It must have something to do with its moisture.

The roses in the afternoon are out of moisture.

When the rose is not collected, it is connected to the roots and leaves. It is part of the plant. In order for plants to maintain their normal vital activities, photosynthesis and respiration must be carried out.

Breathing will only be there if the plant is alive. Photosynthesis requires the participation of sunlight, so photosynthesis does not take place in the absence of light, and in general, photosynthesis is more efficient than breathing.

Roses collected at night, due to exposure to sunlight throughout the day, the whole plant is mainly based on the action of photosynthesis, absorbing CO2 from the air and then synthesizing organic matter with water and sunlight. It is used in a factory, so the concentration is very low. Plants are neutral or weakly alkaline.

Roses are collected in the morning because there is no sunlight at night and the whole plant is mostly breathing. Breathing breaks down organic matter in the body into CO2 and water and obtains energy to keep movement alive. After one night of breathing, the concentration of carbon dioxide in the plant is relatively high, and almost the whole plant is weakly acidic.

The color of the trumpet flower is red in the morning and blue in the evening. The weakly acidic state is more conducive to the decay of flowers, and pigments such as anthocyanins are destroyed more quickly under acidic conditions, so morning roses are more likely to wilt.

Roses are one of my favorite flowers and are often used to express good emotions, if you want to keep the roses in your vase open longer, choose roses that are picked in the afternoon.

Because it has a large water content in the morning, and in the afternoon, it is not easy to wilt after the water evaporates at noon.

Because the various pores of the afternoon rose have been closed, it is not easy to wither.

I think it's because the morning rose is a little more fragile than the afternoon rose.

This has a lot to do with some of the characteristics it has in different time periods.

Because in the afternoon, in fact, the body of this rose is better, and there are more hormones in it.
