Blue flowers are rare and are why 10

Green flowers are relatively rare in nature.

The color of the flowers varies mainly because of the different components (pigments) of the compounds contained in the petals. These compounds can be broadly divided into two types, namely anthocyanins and carotene. Anthocyanins are extremely unstable, red when exposed to acids and blue when exposed to alkalis.

Color, neutral purple, the strength of acidity and alkalinity also directly affects the depth of color. Carotene can make flowers show yellow, orange, red and other colors, and there are many kinds of carotene, and there are more than 80 kinds of carotene. Plants in nature.

There are many species, and the environment in which they live is also different, and it is under the action of two pigments that plants can produce colorful flowers.

Green flowers are relatively rare in nature, because the pigment that forms green is mainly chlorophyll, which is generally found in the stem and leaf tissues of plants, and there are very few in the petals, but green flowers still exist. For example, hydrangeas, it.

The flowers are mostly spherical white and turn blue-green or pink in the later stages. A native Chinese rose, its flowers are large and green, and it is a variant of Yueji. There are also many varieties of flowers of non-ornamental plants such as rice, millet, and onions.

Green. Of course, with the development of technology, human beings are also using genetics, dyeing and other methods to artificially create green flowers, such as green roses.

Blue flowers are also very rare in nature, and the root cause is determined by solar radiation and the physiological characteristics of the flower itself. But compared to the black flower, it seems to be more. But you also can't buy blue flowers from nature. We see a lot of blue.

The colored flowers are also artificially cultivated. From knowing.

Because the blue chromosome base is rarely formed naturally in nature, most of the blue flowers are artificially cultivated.

1. Phalaenopsis, lavender, bellflower, etc. are all blue;

2. The butterfly lead oak butterfly destroys the color of the orchid with multi-fiber and lead species, with beautiful flowers and fragrant flowers, which is a treasure in the tropical orchid and is known as the "queen of the orchid";

3. Lavender, also known as perfume plant, spirit vanilla, vanilla, yellow vanilla, belongs to Lamiaceae Lavender, native to the Mediterranean coast, Europe and Oceania archipelago, and was widely planted in Britain and Yugoslavia, its leaf shape flower color is beautiful and elegant, blue-purple inflorescence is long and beautiful, it is a new perennial cold-resistant flower in the garden;

4. Platycodon, gentian perennial plant, modern bellflower cultivation is thriving in Japan, bellflower color is elegant and bright, flower shape is chic and lovely, is a very popular potted flower and cut flower species in the world.

It is because the cell fluid of safflower contains anthocyanins that are turned from glucose, and when the cell fluid is acidic, the acidic anthocyanins will reflect the long red light wave and appear red, the stronger the acidity, the redder the color, which is the reason for the red flowers.

Both safflower and red leaves contain anthocyanins that are made from glucose in their cell fluid. When the cell fluid is DAO acidic, the anthocyanins appear red, and the more acidic, the redder the color.

When it is alkaline, anthocyanins appear blue, and the alkaline is stronger, becoming blue-black, such as black chrysanthemum, black peony, etc. And when it's neutral, it's purple. Thousands of purples and reds, red and blue, are all anthocyanins shown in different acid-base reactions.

In addition to safflowers, there are also yellow and orange flowers. Orange is similar to the color of citrus, pumpkin and other fruits, and the most typical is carrots, so the pigment that expresses this color is called carotene. There is the size of the carotene to decide whether it is orange or yellow.

Sometimes flowers of different colors grow on the branches of the same plant, and the color on the same branch becomes brilliant because the flowers have a time to change color first. What's even more amazing is that some flowers can change color up to three times a day. For example, the petals of a morning glory turn pink early in the morning, then purplish-red, and finally blue.

But "anthocyanins" are very naughty and form different colors depending on the environment. In acidic solutions, it is red, and the more acidic it is, the redder it is in color. For example, "red line", etc.

In alkaline solution, it will be blue, alkaline, and blue black, such as "black chrysanthemum, black peony", etc. And, when it is in a neutral environment, it is purple, like the "bellflower flower".

But "anthocyanins" are not the only factor that affects the pattern. The difference in the tissue structure of the petals will affect the refraction and reflection of light, which in turn will affect the color of the flower. At the same time, ecological factors will also affect the patterns of light, temperature, humidity, soil nutrient content, etc., and affect the pH value, enzyme, sugar content, and stability of anthocyanins of petal cells, and then affect the synthesis of anthocyanins or the molecular structure changes of some anthocyanins, so that the petals show different colors.

The only natural light on Earth is the sun. Sunlight reaches the Earth's surface with a width of between 290 nanometers and 1,100 nanometers, and we humans can only see part of it with our naked eyes. We call this visible light.

Pigments absorb different wavelengths of visible sunlight, and the light that does not absorb (i.e., reflected light) is the color of plants that are visible to the naked eye.

To introduce the effect of pigments on flower color, the color of flowers is mainly determined by the pigments in the petals. There are many types of pigments, the most important of which are flavonoids and carotenoids. There are more than 80 carotenoids found at present, more than 5,600 flavonoids have been confirmed, and anthocyanins are also important members, and different kinds of carotenoids make flowers look yellow, red, or orange.

Some flowers can be yellow like yellow roses, some can be red like tulips, and some can be orange like calendula.

Anthocyanins are mainly divided into three flavonoid carotenoid alkaloids. Flavonoids can transform the flowers of plants into colors such as pink, red, blue, and purple. Carotenoids can make the flowers of plants look like orange, yellow, purple, etc.

The main expression colors of alkaloids are yellow and orange. Due to the different genes of plant species, multiple amounts and proportions of pigments are synthesized in the body, which is the main factor for the different colors of plant flowers.

Blue flowers are not uncommon, such as trumpet flowers. There are also pomegranate flowers on the mountain, which are generally blue. If we look closely, we will always find blue flowers.

Because blue chromosomal bases are rarely formed in nature, blue flowers are very rare.

Blue flowers are very rare in nature, which is determined by solar radiation and the physiological characteristics of the flowers themselves, which is more than black flowers, but you can't buy blue flowers in nature, and the blue flowers we see are artificially cultivated.

Blue light is absorbed in large quantities but cannot be reflected, so it is naturally difficult to see natural blue plants in nature.

Blue flowers are also present, and I often see them in the grass huts on the side of the road, and there are many of them now.

Morning glory poppy.

In fact, there are not so few blue flowers.

The common ones are: Certain species of iris (e.g. German iris, brook iris).

Certain varieties of orchids.
