Why do morning glories come in different colors?

Some flowers will be based on red, purple, blue, and then take on different shades of color, because there is something called anthocyanins hidden inside them. If you take a closer look at trumpet flowers, there are red, blue, and purple ones, precisely because they contain anthocyanins. If we put a red trumpet flower in alkaline soapy water, it will immediately turn blue.

If we take it out of the soapy water and put it in diluted hydrochloric acid, it will immediately turn back to its original red color. It can be seen that anthocyanins will turn blue when they encounter alkaline substances, and they will turn red when they encounter acidity. The acidity and alkalinity of each plant is different, so the color of the flower is naturally different.

In addition, even though it is the same plant, the pH level in its body changes from time to time, so the trumpet flower sometimes looks red, and sometimes it looks blue-purple. In addition, the temperature will also affect the discoloration of anthocyanins, so the temperature is low in the morning, and the color of the flowers is light; In the afternoon, when the temperature is high, the color becomes darker. Flowers that change based on yellow, orange, and red contain a wide variety of carotene, so there are differences in various flower colors.

Why are flowers so colorful? If you look closely, you can see that the color of most flowers varies between red, purple and blue, and some change between yellow, orange and red. The reason why the flower color can change between yellow, orange and red is due to the action of carotenoids.

There are many types of carotenoids, about 60 of them. The yellow lutein contained in yellow leaves and ripe tobacco leaves is one of the carotenoids. The flower color can change between red, purple and blue because the anthocyanins in the flower cells are at work.

Anthocyanin is an organic pigment that changes color easily and will show different colors as long as there is a slight change in temperature and pH. In plants, there are acidic substances and alkaline substances. Even within the same plant, the pH varies depending on light, temperature, humidity, etc.

I vaguely remember seeing a small experiment when I was a child, which was to put morning glory.

Soak in alkaline water separately.

and vinegar water to observe the color change. Anthocyanins in flower petals.

It is red in acidic conditions and blue in alkaline conditions. However, as the saying goes, phenotype is the result of a combination of genes and environment ......Common morning glories seem to be more blue, but the seeds are not necessarily the same: the content and distribution of anthocyanins may be different from birth, and the color of the petals is also affected by other pigments.

There are varieties of morning glory in different colors in gardening, such as the crimson "scarlet o".'hara", a brownish "chocolate". The current popular Morning Glory has long leaves with large stalks, trilobes, large lobes, and irregular yellow and white patches on the leaves. Flowers 1 to 3 axillary, peduncle shorter than petioles, flowers large, flower diameter up to 10 cm or larger, native to tropical Asia and Africa.

This species is the most cultivated in Japan, called the Asahi flower, and many horticultural varieties have been selected and bred, the flower types are varied, the flower colors are rich and colorful, and it is widely popular in various places. <>

Morning glory discoloration is caused by a gene that causes changes in the pH of cell vacuoles. According to a report in the British journal Nature, the color of morning glory flowers is not only related to the pigments and metal ions contained in the cells, but also affected by the pH of the liquid in the cell vacuoles. Vacuole is a vesicular structure in the cytoplasm that is encapsulated by a vacuolar membrane and contains aqueous cellular fluid, which contains salts, sugars, and other components.

It is understood that scientists selected a morning glory whose flowers are still purple after blooming and compared it with a blue morning glory. It was found that the vacuole pH of the purple flowers remained neutral after they were in full bloom. The vacuoles of the blue flowers will become alkaline, turning the flower color from purple to blue, just as litmus paper turns blue when it encounters an alkaline solution.

Studies have proved that the pH of purple flower vacuoles does not change, which is caused by a defect in a certain gene. <>

Morning glory comes in many colors, the common ones are peach, blue, white, and purple, among others.

Still others are crimson, fuchsia, pink, yellow, and cyan. The flower is funnel-shaped and looks like a trumpet, so it is also called a trumpet flower. Because it contains anthocyanins, it tends to change color when affected by the outside world, so it is very hungry and has ornamental value.

The flowering time is usually in the summer. As an annual herbaceous plant, it is generally only sown in the spring and can bloom after 40 days of sowing, so the flowering period is usually in the summer wax bridge season. It has a long flowering period of up to 100 days, so it can be enjoyed continuously, and because it can change color, it is very beautiful.

Morning glory comes in crimson, pink, purple, purple, pink, red, pink, yellow, white, and cyan, and its petal edges vary widely, with the most common colors being peach, blue, white, and purple. It blooms for up to 5 months, roughly from May to October each year.

Morning glory, also known as trumpet flower, is an annual winding herbaceous plant, its vitality is very tenacious, likes a warm, ventilated and sunny environment Xiaoshan, more resistant to drought and high temperature, not cold-tolerant. When flowering, the shape of the flower is funnel-shaped, the flower is large, the number of flowers is large, the flower color is more diverse, and the flower contains a pigment, which will change color when it encounters the liquid in the core of different properties.

Morning glories come in a wide variety of colors, including crimson, pink, bright red, pinkish-white, yellow, blue, purple, cyan, fuchsia, etc. It is an annual entwined herbaceous plant, and its flower shape is very similar to that of the trumpet, so it is also called the trumpet flower, which is generally sown in spring and blooms in summer and autumn.

Morning glory is a very common flower, it has a lot of flower colors, the more common colors are crimson, pink, bright red, pink white, yellow, blue, purple, cyan, fuchsia and so on. In addition to the solid color, morning glory also has mixed colors, and the change of flower color is more than that of Brother Bu.

The shape of the morning glory flower is very similar to that of the trumpet, so it is also called the "trumpet flower" in some places. In general, morning glory is sown in spring and blooms in late summer and early autumn, and it can be seen in many places, and it is a relatively common ornamental plant.

The flower language of morning glory

As we all know, every flower has its words, and the words of morning glory are fame and love forever. Morning glory is a very good flower, no matter what kind of environment it lives in, it can survive tenaciously, this spirit is very suitable for both fame and love.

The course of the day of morning glory is as follows:

First of all, in the morning, the trumpet flowers begin to open, and the color is red. Then, in the morning, after some sunshine, the color of the trumpet flower begins to change, gradually changing from red to purple. Finally, in the evening, the trumpet flowers begin to slowly wither.

Reasons for the color change of morning glory:

1. Pigment changes.

The color of morning glory will change because it contains a pigment in its body, called anthocyanin, which will change the overall color of morning glory, and the pigment will be affected by different liquids, when the nature of the liquid in the body changes, the color of morning glory will change.

2. PH change.

Specifically, the color change of morning glory is caused by the change in the pH of the fluid in the body, when the fluid in the body is acidic, then the anthocyanins will turn red when combined with it, and if the liquid in the body is alkaline, then the anthocyanins will react with it and it will appear blue.

3. Genetic composition.

In addition to being influenced by the outside world, the color change of morning glory is also affected by its own genes, for example, some purple morning glory may be caused by genetic defects that cause it to turn purple. Therefore, if you see a peculiar color morning glory in your daily life, then it may have a genetic defect or gene mutation.

4. Plant characteristics.

Morning glory comes in a variety of colors, in addition to its own color variation, but also because of its wide variety, there are about 60 different types of morning glory in the world, and the most common color is blue. Rose-red and white, which are distinguished by the shape of the main round-leaved petunia and the heart-shaped petunias, both of which have the characteristic of changing colors.
