What plants have phototropism

This article introduces the explanation of plants with phototropism in the aspect of green plants and flowers, please continue reading!

What plants have phototropism

Plants with obvious phototropism include sunflowers, cotton, wheat, potatoes, peas, radishes, sunflowers, bowl lotus, cannas, mint, celosia, bougainvillea, jasmine, and many more. Actually, from the lower-level algae to the higher-level angiosperms, almost all have phototropism.

What is the phototropism of plant growth

Most plants have phototropism, which is beneficial for the photosynthesis of leaves. Moreover, phototropism is divided into positive phototropism and negative phototropism, and they will turn towards the top with the light. The roots of most plants are negatively phototropic, that is, more roots grow towards the shady side with less light.

Therefore, if a plant has phototropism, it is generally a positive flower plant, so it can be placed in a sunny place for maintenance throughout the year to grow better.

Which plants have phototropism

Sunflowers turn towards the sun (image)

NO1, Sunflower

The reason why sunflowers turn towards the sun is that sunflowers themselves have phototropism. In fact, it is not the flower head of the sunflower that turns, but the neck of the sunflower, which contains a special "plant growth hormone".

So it moves with the sunlight, but not all sunflowers do this. When the sunflower head matures, they will always face east.

NO2, Potato

Potatoes are plants that prefer a sunny environment, especially during their growing period. They require a relatively high amount of light, and the better the lighting, the faster they grow.

Usually, the leaves of potatoes can fully perform photosynthesis. After the tuber growth period, proper lighting can make the tubers form faster, and the starch content can also be effectively increased.

NO3, Rose

It is also a positive flower plant, so it can be placed in a sunny place for maintenance throughout the year. If there is not enough light, the branches and leaves will grow sparse, the branches will grow excessively, and it will be difficult to grow new branches and leaves, and there will be few flower buds.

Even if it blooms, the flowers will be small and colorless, so it is necessary to ensure sufficient light. And if you fertilize and prune it frequently, it will bloom more beautifully.

NO4, Jasmine

Jasmine is also a flower plant that thrives in a well-lit environment, requiring sunlight throughout the year. Only by getting more sun can it bloom more, have a stronger fragrance, and have lush foliage.

Some friends grow it in a small courtyard, and it grows into a large plant, flowering countless times. Jasmine loves the sun, as well as fertilizer and pruning. Only by getting more sun can it grow normally and bloom continuously.

NO5, Peony

No matter which type of peony, the flowers are all very large, beautiful and elegant, and can be planted in slightly larger pots.

We can also plant it in a small courtyard, but it must be kept in a place with plenty of light, with at least 6 hours of sunlight every day to make it bloom smoothly.

NO6, China Rose

To grow China roses well, they should be placed in a sunny location, especially in spring and autumn.

In the summer, when temperatures are high, China rose potted plants can be appropriately shaded from the sun and placed in a cool and ventilated place for maintenance, but they must get plenty of sun during other times, and they are also somewhat cold-tolerant.
