What are the functions of mimosa

What are the functions of mimosa? Shy grasslands are native to tropical South America, like to be warm and humid, and are not strict with the soil. The flowers, leaves and pods of mimosa have better ornamental effect, and are easy to survive, so they are suitable for potted flowers in balcony and indoor. So what are the functions of mimosa? The following editor will give you a brief explanation.

The function of mimosa

1. Mimosa can predict the weather.

Mimosa is a wonderful plant that can predict changes in the weather. If you touch it with your hand, its leaves close quickly and open slowly, indicating that the weather will clear up; if you touch mimosa, its leaves contract slowly, droop slowly, or even reopen a little bit, this means that the weather will change from sunny to overcast or it is going to rain.

The speed of the opening and closing of mimosa leaves can foretell the weather, mainly because in the neck of mimosa leaves, there is a small drum-shaped parenchyma tissue-leaf mattress, which is filled with water. When you touch the mimosa leaf with your hand, as soon as the leaf vibrates, the water in the lower cells of the leaf mattress immediately flows upward to both sides, so that the lower part of the mattress shrivels down, while the upper part bulges up, the petiole droops and the leaf closes. Therefore, the closure and opening of leaves are caused by the swelling and pressure of leaf mattresses. The expansion and pressure of the leaf mattress is closely related to the humidity in the air. When the air humidity is very small, the expansion and pressure effect of the leaf mattress is obvious, and the closing and opening speed of the leaf is fast; when the air humidity is very high, the opening and closing speed of the leaf is slow. Therefore, the speed of opening and closing of mimosa leaves indirectly reflects the humidity in the air and can be used as a reference for weather forecast.

2. It can also predict earthquakes.

Mimosa can predict earthquakes. According to Turkish seismologist Erjiang, a few hours before a strong earthquake, the leaves of mimosa, which are sensitive to the outside world, suddenly shrink and then wither. In earthquake-prone Japan, scientists have found that under normal circumstances, mimosa leaves open during the day and close at night. If the leaves of mimosa close during the day and open at night, it is a sign of an earthquake. For example, at 7: 00 a.m. on January 11, 1938, the mimosa began to open, but at 10:00, all the leaves suddenly closed, and sure enough, a strong earthquake occurred on the 13th. Members of the earthquake Club of Japan in 1976 observed the abnormal closure of mimosa leaves many times, resulting in an earthquake.

3. It has a special ornamental function.

Mimosa plant shape scattered, feather leaves slender and beautiful, its leaves are closed at a touch; mimosa flowers are many and beautiful, charming, giving people the impression of weak and elegant. It can be planted in the corner of the courtyard or potted in the window. When giving flowers, gently cover the potted plants with pink tulle and tie them with pink ribbons and knots. It would be more interesting if you could adorn it with pink mohair balls.

Pharmacological effects of mimosa root

① has antitussive and expectorant effect on mice. Root decoction has obvious antitussive effect (ammonia spray), but the expectorant effect is not significant (phenol red method).

The effect of ② on smooth muscle in isolated bronchopulmonary perfusion test of guinea pigs showed that the root decoction had no relaxing effect, but had obvious anti-acetylcholine effect on isolated rabbit ileum, and the effect of extract No. 1 (alkaloid) was also significant. Extract No. 3 (flavonoid glycoside) and No. 4 (lactone substance) had weak antiacetylcholine effect.

The antibacterial root of ③ had strong bacteriostatic effect on Staphylococcus aureus and Staphylococcus Albus and Diplococcus catarrhalis in vitro, and also had an effect on Escherichia coli, but had weak effect on Diplococcus pneumoniae, Type An and B Streptococcus and Influenza bacilli.

Total alkaloids and root decoction had obvious inhibitory effect on Asian influenza A virus, rhinovirus type 17 and adenovirus type 7 (primary monolayer cell culture of human embryonic kidney).

On the role of mimosa which editor introduced here, I believe you also have a certain understanding of mimosa, thank you for your attention to us.
