Do sunflowers really follow the sun?

In fact, many people have always had a question, why does the sunflower's flower plate keep rotating against the sun, is it because it has a mind?

The sunflower revolves around the sun during the day, so what is it doing at night?

It is related to two things in the sunflower body, auxin and lutein.

The main reason why sunflowers rotate towards the sun is the influence of light. Its auxin is distributed by the backlight, and the concentration of auxin on the side facing the sun is lower, and the concentration of auxin on the side of the backlight is higher, so the backlit side grows faster, and the light-oriented side grows slower, which makes the stem bend against the light, making it towards the sun.

The growing sunflower flower starts with its head facing east every day, and then follows the sun, moving westward little by little. Back to the east in the evening.

The reason why it is able to rotate with the sun is because genes (circadian rhythm) and some hormones (mainly ghrelin) are at work.

Scientists have found that the auxin in the sunflower causes the backlit side to grow faster. Luteoxi, on the other hand, is the opposite of auxin, which inhibits cell growth and accumulates on the sunny side of the sunflower, resulting in different growth rates on both sides of the sunflower stem, which also causes the sunflower flower to grow in the sun.

What would happen if the sunflower was interfered with in its ability to track the sun?

It will be crippled. For example, the number of leaves is smaller, the area is smaller, and the biotin is reduced.

If you grow a sunflower indoors and provide a fixed top light source, will it also swing?

Yes, it will still oscillate on the biological rhythm in its body for a few days.

Therefore, the sunflower rotates with the sun, which is the effect of the biological clock (circadian rhythm) and auxin secretion.

As the sunflower matures, the growth rate decreases, and its flower disc stops swinging, facing east.

Is it still facing east?

Because the sunflower is cute, it should be a warm flower.

Bees love warm flowers.

Because of the growth factors of sunflowers, as well as the growth needs of sunflowers, it is necessary to follow the sun, so as to ensure the ornamental value of sunflowers.

Because the flowering period of sunflower is generally in July and August, and its plants contain a very wonderful auxin, this auxin causes the sunflower to rotate with the sun, because this can make its particles fuller and grow better.

The stems of sunflowers produce a special growth hormone that rotates around light.

Sunflowers rotate with the sun because of the auxin underneath the flower disc, which promotes the growth and reproduction of the plant. There is also the restriction of sunlight, and the stem will drag its flower disc and bend towards the side with the sun. When there is sunlight, sunflowers will rotate with the sun.

When the sun goes down, the auxin it contains is redistributed again, so it returns to its original position.
