Why do you need to turn the pot in the process of flower maintenance?

We often turn the flowerpot in the process of flower conservation, we know that this is mainly to enable flowers to receive sunlight evenly. But have you considered the truth of this? The editor will give you a detailed introduction of the reasons for turning the pot in the process of flower maintenance, and interested friends can understand it together.

Turn the pot, that is, the direction of the flowerpot is often changed during the flower growth. Due to the phototropism of some flowers and plants, if the light is not often adjusted by turning the basin, bad shapes such as partial crowns will appear, affecting the ornamental value. Why do flowers have phototropism? This is due to the effect of auxin in vivo.

Auxin is mostly concentrated in the parts where the growth is exuberant, such as meristem, cambium cells and young leaves of stem tip, bud and root tip, so it shows that the phototropism of young leaves and shoots is strong, while that of old leaves and old branches is weak or absent. The experimental results show that light can change the distribution of auxin, and the phototropism of flowers is related to the uneven distribution of auxin caused by unilateral light.

For example, some people have done experiments with geranium. it has been determined that the auxin on one side of the stem light is 35%, and the side of the backlight is 65%. The cells on the side with more auxin grow faster, while the cells on the less side grow slowly. as a result, the stem bends to the slow-growing side, that is, toward the sunny side, making the plant show phototropism. Because of this, if you do not turn the pot for a long time and let it grow naturally, the plant will grow on the wrong side. Some flowers such as orchids cultivated by flower friends sometimes have crooked leaves because they are not often turned into pots from the beginning of the seedlings.

In order to maintain the symmetrical plant shape of flowers, it is necessary to pay attention to regularly changing the direction of potted flowers, especially in the peak period of flower growth, the direction of the flowerpot should be rotated every 7 days or so. It is best to rotate the flowerpot 180 °each time, so that the leaves can be evenly distributed, the flower head is straight, and the plant is upright without askew.
