Why does the color of the flowers change three times a day?

The reason why flowers have a variety of bright colors is due to the presence of pigments in the cell fluid in the petals. The pigment contained in the flower is closely related to the concentration of acid and alkali, as well as nutrients, moisture, temperature and other conditions. And often with the change of these objective conditions, therefore, the flowers will have different shades, different shades of color.

Hibiscus flowers. Three changes a day, that is, as the temperature rises, anthocyanins.

and the concentration of the acid has changed, resulting in a phenomenon that arises.

A teacher at an international school asked an open-ended question: What do you think about food shortages in other countries? African students asked

What is food? European students ask: What is a shortage?

American students ask: What do you mean by other countries? The Chinese student asked

What do you call your own opinion?

The discoloration of the hibiscus is caused by changes in temperature, different soil quality and the duration of sunlight, and when the temperature rises or falls, the cyanocandin in the flowers of the hibiscus is present.

The content also changes, and thus changes color, and the acidity and alkalinity of the soil.

and the length of time spent in light throughout the day can also cause the color of the hibiscus to change.

1. Temperature changes

The color of the hibiscus changes, mainly because the cyanocyanin content in the flowers increases or decreases, and the direct factor affecting the cyanocyanin content is the temperature, when the temperature rises or decreases, the cyanocyanin in the body of the hibiscus also changes, resulting in discoloration.

2. The soil is different

Planting wood hibiscus flowers to celebrate the song.

The soil texture will also affect the color of its flowers, if the stove is used in the early stage of cultivation is a more acidic soil, then the flower color of the hibiscus will be light, and the alkaline soil is added in the later maintenance process, which will make the flower color of the hibiscus darker.

3. Light duration

Some hibiscus flowers are also different in the morning and at night, which is caused by the length of light, the early morning hibiscus receives light light for a short time, the flowers will appear reddish, but as the time of the day accumulates to receive light, it will turn a deeper purplish red at night.

The colors of hibiscus flowers change three times a day are white, pink, and bright red.

The flowers of hibiscus not only have plump petals, but also have magical color-changing wisdom. The flowers of the hibiscus change color three times a day, when they bloom in the morning, they turn pink in the morning, and they turn bright red in the evening. Wang Anshi would write the poem "The color of the dew is not thick", probably because he observed this discoloration of the hibiscus flowers.

In the plant world, there are many plants that have discoloration, such as the well-known honeysuckle flowers, which change from white to golden yellow. In the tropics, we can see a plant called Gentleman, whose flowers are white at first bloom and turn bright red after a while.

Through our introduction, I believe you have a deeper understanding of the color changes of hibiscus flowers.

How does hibiscus flower change color, hibiscus flower believes that everyone is no stranger to is a highly ornamental plant, it also has a long flowering period, many varieties, many flower colors, peculiar flower shapes and other characteristics, deeply liked by everyone, so how does hibiscus flower change color?

1. The principle of color change

Hibiscus flowers will change color and nutrients, moisture, temperature, generally in the maintenance of hibiscus flowers for the plant to provide water is color, hibiscus flower petals will change color, and under natural conditions hibiscus flower discoloration is related to the temperature of plant growth, when the temperature changes, the acidic concentration in the petals is also changing, and then react with anthocyanins to appear different colors, so hibiscus flowers will change color.

2. Provide moisture

Hibiscus flowers are suitable for growing in a humid environment, so when caring for hibiscus flowers, it is necessary to provide proper water to the plant and keep the soil moist. At the same time, it is also necessary to pay attention to the amount of watering when providing water to the plants, and generally only need to provide water for the plants when the soil is relatively dry, so as to avoid the death of the plants due to water accumulation.

3. Supplement nutrients

Hibiscus flowers have a greater demand for nutrients in the process of growth, so it is also necessary to provide appropriate nutrients for the plants when maintaining hibiscus flowers, improve the growth rate of the plants, and at the same time pay attention to the amount of fertilizer when providing nutrients for the plants.

4. Suitable soil

When planting hibiscus flowers, it is also necessary to choose the right soil. Hibiscus flowers are suitable for growing in soil with rich nutrient content and good drainage, so it is best to use sandy loam soil with rich trace element content and good air permeability when planting hibiscus flowers, and regular ones are needed after planting'Loosen the soil and prevent it from clumping.

How to prune hibiscus flowers

1. Pruning time

When it comes to pruning hibiscus flowers, you need to choose the right pruning time. Hibiscus flowers grow more rapidly in spring, at this time it is necessary to prune the hibiscus flowers properly to make the plant grow more lush, and at the same time, at the end of the flowering period of the hibiscus flowers, the plants also need to be properly pruned to help the plants save nutrients and make them grow healthily.

2. Pruning method

When pruning hibiscus flowers, you need to choose the right tools, it is best to use scissors with a sharp edge for pruning, and at the same time, when pruning in spring, you need to cut off the branches that are not growing well and the branches that are too long, and when pruning the hibiscus flowers after the flowering period, you need to cut off the withered buds and overgrown branches.

3. Post-maintenance

After pruning, the plant needs to be kept in a ventilated and cool environment, and it is necessary to provide appropriate water for the plant during maintenance, so that the soil is in a moist state, so that the plant can recover as soon as possible, and at the same time, it is also necessary to provide appropriate nutrients for the plant, improve the growth rate of the plant, and make it grow more vigorously.

4. Precautions

When pruning hibiscus flowers, you need to pay attention to disinfection and sterilization. Before pruning the plant, the pruning tool needs to be disinfected and sterilized, so as to avoid the bacteria on the tool from infecting the plant, and at the same time, the pruning wound of the plant needs to be disinfected and sterilized after pruning to help the wound of the plant heal as soon as possible, and it is also necessary to spray water on the plant during maintenance to prevent the plant from breeding bacteria during the maintenance process.

Hibiscus flowers change color because as the temperature rises, the concentration of anthocyanins and acids changes in hail heights, a phenomenon caused by the spine of thought.

Hibiscus flowers like warm, humid environments, are not cold-tolerant, avoid drought, and are resistant to water and moisture. The soil requirements are not high, and barren land can also grow. The flowers are solitary in the axils of the leaves at the end of the branches. Flowers and leaves can be used as medicine, which has the effect of clearing heat and detoxifying, reducing swelling and draining pus, cooling blood and stopping bleeding.

Varieties: White-flowered hibiscus, white flowers; Drunken hibiscus, double petals, the flowers are pure white at the beginning of blooming, and then turn dark red, which is a rare and precious variety.

The stem bark of hibiscus flower contains 39% cellulose, and the stem bark fiber is flexible and water-resistant, white and flexible, and water-resistant, which can be used for textile, rope making, cable, hemp substitutes and raw materials, and can also be used for papermaking. The ancients also used wood hibiscus flowers to pound the juice for pulp, and dye silk for accounts, which is famous"Hibiscus tent"。It can also clear away heat and detoxify, reduce swelling and drain pus, cool blood and stop bleeding.

for pulmonary fever, cough, menorrhagia, leucorrhoea; External use for the treatment of rough carbuncles, sores and boils, mastitis, lymphadenitis, mumps, burns, snake bites, bruises.

1. Temperature. The hibiscus flower will change color because of the temperature nutrition, the temperature at which it grows increases or decreases, then its flower color will change, the normal white in the morning, the temperature rises at noon and becomes pink, and in the afternoon it becomes dark red at sunset. This is mainly because after the content of cyanocyanin substances contained in hibiscus flowers becomes high, a chemical reaction will occur, and this chemical reaction is the main reason for the discoloration of hibiscus flowers.

2. Different varieties. There are many varieties of hibiscus, and some varieties will change their color as they grow longer, such as the potpourri hibiscus, which is pink in the first year, and bright red in the second year. However, there are some varieties that do not change the color of the flowers, such as the double-petaled hibiscus flower.
