Today, I will share with you some knowledge about sunflowers. We all know that sunflowers turn towards the sun, so why is this? Let's take a look.


Because the sunflower is a devout follower of the sun, turning in the direction of the sun every day, which is also the source of its name.


Facing the sun is the result of phytohormonal regulation. Sunflower contains an auxin that can make plants grow taller and larger, but it is very afraid of sunlight, and when stimulated by sunlight, it will run to the backlit side to hide.


Lutein does the exact opposite, inhibiting the growth of plant cells, while light enhances its activity. So lutein builds up on the sunny side, causing the sunflower's stem to bend toward the sun.


During the day, sunflowers follow the sun, always turning in one direction. So, how did it get back in place the next day?


Don't worry, after sunset, auxin and lutein redistribute. The disc will gradually turn back. The bent branch will now stand upright again. Sunflowers follow the sun, but they don't turn at the same time.


The sunflower disk is oriented at about 12 degrees to the sun, which means its spin rate is behind the sun.


Because sunflowers are devout followers of the sun, they rotate in the direction of the sun every day, and dedicate all the love of their life to the sun, but they never say it, so the flower language of sunflowers is loyal and silent love .


Sunflower also has many functions, let's see what value she has?
