Is the mimosa poisonous?

Mimosa originated from tropical South America. With the international development, mimosa has been widely cultivated in China. Mimosa has a strong ability to adapt to the environment and likes to grow in a warm and humid environment. It is more common in hillside jungles and roadside humid places. Now many families plant mimosa as a family ornamental plant. Let's see if mimosa is poisonous.

A brief introduction to Mimosa

We all know that plants do not have a nervous system, which is an important feature that distinguishes them from animals. But the stress response of mimosa behaves more like animal behavior. Why? This should start from the physiological composition of mimosa.

In the position of the petiole and the base of the leaf of mimosa, there is an inflated part, which is called the leaf pillow. And the leaf pillow is the core reason for the shyness of the mimosa. There is a vascular bundle in the middle of the leaf pillow, surrounded by parenchyma. When the leaf pillow which is most sensitive to stimulation is touched, it will cause the cell fluid of the parenchyma cells in the upper half of the leaf occipital to be discharged, resulting in an imbalance of swelling pressure between the upper and lower halves, resulting in the closure and sagging of the leaves.

The stress behavior of mimosa takes only 0.08 seconds before and after the occurrence, that is to say, the conduction velocity is as high as 10cm/s, which can be said to be very fast. And the time to restore the original state will take about 10 minutes for 5 Murray.

The reason why mimosa is shy is closely related to its native environment. The shy prairie comes from tropical South America, where the climate is bad and there are often high winds and torrential rains. In order to protect itself, when the first drop of Rain Water falls on the mimosa leaf, it will close the leaf promptly and effectively and hang its petiole to avoid the damage of the storm, which is the self-adjustment of the biological world.

Second, the classification of mimosa

There is no general classification of mimosa in variety, but it can be divided into prickly mimosa and non-prickly mimosa in appearance.

① has prickles on mimosa-that is, small white hairs grow from the neck of mimosa, with small spines and slightly hard branches and leaves.

② no prickly mimosa-the stem is smooth, without tomentose, and there is no thorn at the branch and leaf bifurcation.

III. Growth habits

The flowers and leaves of the mimosa and its pods have a good ornamental effect, and it is easy to survive, so it is most suitable for potted plants on the balcony and indoors, and it can also be well planted in the courtyard. and the mimosa is different from the general plant, when it is touched by people, the petiole will droop and the leaves will close, so people understand it as shy. It is native to tropical South America and likes a warm and humid environment, but it does not have high requirements for soil.
