mimosa(han xiu cao )

Mimosa method:

Raw materials for making Mimosa:

Champagne (or sparkling wine): 1 / 2 oz, orange juice: 1 / 2 oz. Wine glass.

Steps for making Mimosa:

Pour the juice into a glass and top with champagne. Orange can also be used as decoration.

Characteristics of Mimosa spp

This kind of cocktail based on champagne is described as the most delicious and luxurious orange juice in the world. People in the upper class originally called it langxiu champagne, but because its color is very similar to the bright yellow Mimosa, it was named Mimosa. In Italy, it's also called backsfizz. The bottom of the wine bottle is mountain shaped, not to make the capacity look more, but for its own sake. The longer the wine is stored, the more fragrant the wine is. However, tartar and tannic acid will be produced in the process of storage. When the wine bottle is standing, the sediment will precipitate to the bottom. If the bottom of the bottle is flat, the sediment is easy to be injected into the cup with the wine. If the wine bottle is mountain shaped, the sediment will precipitate in the depression, so this problem will not occur.

mimosa

Mimosa pudica (scientific name: < imimosa pudica < / I Linn.): it is a perennial herb or subshrub of Leguminosae. Because its leaves respond to heat and light and close immediately when touched by external force, it is named Mimosa pudica. It looks like a ball of wool. The fruit is oblate after flowering. The leaves are feathery, compound and alternate, palmately arranged. Flowering after midsummer, head oblong, 2-3 in axils. The flowers are white and pink, with bell shaped calyx, 8 tiny calyx teeth, four lobed petals, four stamens and glabrous ovary. The pod is flat with one seed per pod node, and the internodes fall off at maturity. The flowering period is September.

The flowers, leaves and pods of Mimosa have good ornamental effect, and it is easy to survive. It is suitable for potted flowers on balcony and indoor (people's eating or excessive contact with Mimosa will also cause hair loss). It can also be planted in the courtyard and other places. Mimosa is different from other plants. When it is touched by people, its petioles droop and its leaflets close. Therefore, people understand it as "shy", so it is called induction grass, hehucao, Mimosa, zhimimosa and baochou grass (Cantonese). Native to tropical South America, it likes to be warm and humid, and has general requirements for soil.

morphological character

It is a scattered, subshrub like herb, up to 1 m in height; its stem is cylindrical, branched, with scattered, recurved hook spines and inverted bristles.

Stipules lanceolate, 5-10 mm long, setose. Pinnae usually 2 pairs, finger like, 3-8 cm long; leaflets 10-20 pairs, linear oblong, 8-13 mm long, 1.5-2.5 mm wide, apex acute, margin setose.

Inflorescence globose, ca. 1 cm in diameter, with long pedicels, solitary or 2-3 in axils; flowers small, reddish, numerous; bracts linear; calyx minimal; corolla campanulate, lobes 4, outside pubescent; stamens 4, extending beyond corolla; ovary short stalked, glabrous; ovules 3-4, style filiform, stigma small.

Pods oblong, 1-2 cm long, ca. 5 mm wide, flat, slightly curved, margin undulate, bristly, nodes abscisic at maturity, margin persistent; seeds ovate, 3.5 mm long. The flowering period is from March to October and the fruiting period is from May to November.

Species difference

Because the leaves of mimosa and Tamarindus are feathery and compound, it is easy to confuse the two plants.

Habitat of producing area

Native to tropical America, it has been widely distributed in tropical regions of the world. Produced in Taiwan, Fujian, Guangdong, Guangxi, Yunnan, etc. It is often cultivated in the Yangtze River Valley for viewing. Mimosa like warm and humid, sunny environment, suitable for good drainage, rich in organic matter sandy loam, strong plant, rapid growth, strong adaptability.

Perception characteristics

Different from animals, plants have no nervous system and muscles. They don't perceive external stimuli. Unlike other plants, Mimosa, when touched by the outside world, its petiole droops and its leaflets close. This action is understood as "shyness", so it is called Mimosa, mimosa and Mimosa.

Mimosa cells are supported by a network of tiny proteins called actin (i.e. leaf occipital anaphylactomes). When the closed movement occurs, the phosphorylation of actin will fall off. As long as Mimosa absorbs the compound that does not let the phosphorylation fall off, it will not change after touching. When actin bundles disperse, the cells are destroyed, resulting in water running out, resulting in closed movement. Actin is generally found in the muscle fibers of animals and is related to muscle contraction. It also exists in Mimosa, which is quite rare.

The movement of plants is usually caused by the change of intracellular turgor. Most mature plant cells have a large vacuole. When the vacuole is full of water, it compresses the surrounding cytoplasm and makes it adhere to the cell wall tightly. It gives the cell wall a kind of pressure and makes the cell expand hard, like a balloon full of air. The concentration of organic and inorganic substances in the vacuole determines the osmotic pressure, and the osmotic pressure can determine the direction of water diffusion. When the vacuole concentration increased, the osmotic pressure increased, and water diffused from the outside to the inside into the vacuole, which increased the swelling pressure of the cells and made the cells swell; on the contrary, the cells shrank. This process can only cause slow movement, such as the opening and closing of stomata.

If the leaves of Mimosa are touched, they will close up immediately. The greater the power of touch, the faster the closing, and the whole leaf will fall down, like powerless. The whole action will be completed in a few seconds. The leaves and petioles of Mimosa have special structures. At the base of petiole and leaflet of compound leaf, there is a relatively enlarged part, which is called leaf pillow. The occipital lobe is most sensitive to stimulation. Once touching a leaf, the stimulation immediately spreads to the pillow at the base of the petiole, causing the two leaflets to close, and the contact force is greater. It not only spreads to the pillow at the base of the petiole, but also quickly spreads to the pillow at the base of the petiole, and the whole petiole droops. Why is that? This is because there is a large vascular bundle in the center of the occipital, which is surrounded by parenchyma with many intercellular spaces. When the vibration is transmitted to the occipital, the cell fluid in the parenchyma cells of the upper part of the occipital is discharged into the intercellular space, so that the turgor pressure of the upper part of the occipital is reduced, while the original turgor pressure of the lower part of the occipital parenchyma cells is still maintained. As a result, the leaflets stand upright, the two leaflets close, and even the whole leaf droops. Some people have done research, Mimosa in 0.08 seconds after being stimulated, the leaves will close. After stimulation, the conduction speed is also very fast, with the highest speed of 10 cm per second. After stimulation, after a period of time, everything slowly returned to normal, the leaflet expanded again, and the petiole also stood up. The recovery time is generally 5-10 minutes. However, if we continue to tease and stimulate its leaves, it will feel "bored" and no longer have any reaction. This is because continuous stimulation makes the cell fluid in the occipital cells lose and cannot be replenished in time.

This special ability of Mimosa has its historical roots. Its hometown is in Brazil in tropical South America, where there are often strong winds and heavy rain. Whenever the first drop of rain hit the leaves, it immediately closed the leaves and drooped the petioles to avoid the damage of the storm. This is an adaptation to the changes of the external environment. In addition, the movement of Mimosa can also be seen as a way of self-defense. Once animals touch it, it will close the leaves, and animals will not dare to eat it.

At the base of petiole and petiole, there is a larger part called "mattress". The response of the mattress to stimulation is very sensitive. There are many parenchyma cells in the center of the mattress. When these cells are quiescent, they will transport the negatively charged chloride ions to the cells and the oxygen ions to the outside of the cells, so as to maintain a certain potential difference between the cell membrane and the adjacent areas, which is called quiescent potential. When the external stimulation exceeds a certain limit, the differential permeability will suddenly change, and a large number of positively charged calcium ions will rush into the cells, while potassium ions will move in the opposite direction, increasing the membrane potential, or even becoming a positive potential, resulting in action potential. This phenomenon is called depolarization. When the cell reaches the action potential, that is, when depolarization occurs, the differential permeability of the cell membrane will disappear, so that the water stored in the vacuole will be discharged instantly, and the cell will lose its turgor pressure and become paralytic. Therefore, when the basal part of petiole was stimulated, the turgor pressure of parenchyma cells in the upper part of the petiole decreased, while the parenchyma cells in the lower part of the petiole still maintained the original turgor pressure, causing the leaflets to stand upright along the petiole direction. The vascular bundles in the petiole form a large pipe in the mattress to hold the water discharged from the mattress.

Mode of reproduction

Mimosa is a taproot plant with few fibrous roots, which is suitable for sowing and propagation, and it is best to adopt the method of direct seeding, so as to avoid damaging the root by transplanting; if it must be transplanted, it should be transplanted at the seedling stage, otherwise it is not easy to survive. As an annual cultivated Mimosa, it is generally sown indoors in early spring.
