Common parasitic plants, what are the parasitic plants

There are many species of parasitic plants, such as Liedang, wild mushroom, and Rafflesia.

Mulberry parasitism, Willow Yama, etc. They each parasitize in different ways, and there are generally two types: holoparasitism and hemiparasitism.

People are most familiar with the cuscuta seed.

Its whole body is golden yellow and filamentous. Say it's a plant, it doesn't have a single green leaf, you can't see its roots, it says it's not a plant, but it blooms, seeds, and spreads offspring. In spring, the seeds germinate and also have roots, mainly relying on the nutrients in the seeds, and there is a small amount of chlorophyll in the stems.

It can produce very few nutrients. But once it finds a host, the roots quickly die, and it lives a fully parasitic life. Cuscuta is the great enemy of crops, the light one is seriously reduced, and the heavy one has no harvest.

Because the dodder has no roots and no mouth, how does it live? There are many suckers growing on the stems, and the elephant's mouth sticks directly into the bark of soybeans and other plants, and it has a sucker every 10 centimeters, which can survive alone, so it reproduces and spreads quickly.

Mistletoe. Unlike dodder seeds, which are herbaceous plants, mistletoe is woody plants. It is 30-60 cm high, with clumped branches, branched, able to flower and bear fruit and evergreen leaves all year round. It is mainly semi-parasitic on mistletoe.

On tall trees such as oak trees, elms, and poplars. The seed is a brilliant way to disperse, and it is widely sown by birds that love to eat its fruit. The big bird swallows the fruit, and because the seeds cannot be digested, it is discharged from the droppings on the tree at will, and the small birds rub their beaks on the bark because of the juice, and the seeds stick to the tree to germinate.

Mistletoe has roots and extends its roots into the cortex of the parasitic tree to absorb nutrients. In winter, the parasitic mistletoe tree loses its leaves, while the mistletoe parasitizes the green branches and green leaves, and in addition to absorbing the nutrients of others, it can also carry out some photosynthesis on its own.

For this reason, botanically it is called a semiparasitic plant.

In your daily life, you must not eat drugs you don't understand at will, so as to avoid the risk of poisoning. So what is this mountain bean root, let's briefly introduce it today.

In fact, mountain bean root comes from a plant called Vietnamese locust. Vietnamese locust belongs to the genus Leguminaceae, which belongs to the same family as the locust flower, and can be said to be a "relative". However, unlike the tall locust trees, the Vietnamese locust is a shrub plant, so it is usually a small tree.

The distribution of Acacia vietnam in China is relatively limited, and there are wild resources mainly in Guangxi, Guizhou and Yunnan. Abroad, it is also distributed in the northern part of Vietnam.

The part of the Vietnamese acacia is its root and rhizome, and the medicine is called the root of the mountain bean. Then let's mainly introduce the efficacy and application of mountain bean root.

1.Clear away heat and detoxify, improve pharynx and reduce swelling.

The bitter and cold taste of mountain bean root is attributed to the lungs and stomach meridians, and traditional Chinese medicine believes that it is bitter and cold, so the heat clearing and detoxification power is relatively strong. And it also has the effect of reducing pharyngeal swelling, so it is known as the most important medicine for heat and poison accumulation and sore throat. Pharmacological experiments have also found that the root of mountain bean has antibacterial and anti-inflammatory effects.

Therefore, for wind-heat cold, lung and stomach heat on the throat, or sore throat caused by warm and evil qi, as long as it is caused by real heat, mountain bean root has a good effect of detoxification and pharyngeal. If it is an ordinary mild disease, you can directly use the mountain bean root single product to decoction or gargle.

2.Clears the lungs and stomach from heat.

The root of the mountain bean belongs to the lungs and stomach meridians, so it has the effect of clearing the lungs and stomach. If the stomach is really hot, it is easy to have a series of symptoms such as dry mouth and thirst, swollen and sore gums, bleeding, bad breath, nausea and vomiting. If the lung heat is blazing, there will be cough and wheezing, chest pain, sore throat, yellow phlegm and other manifestations, while the mountain bean root has a good effect of clearing the lungs and stomach and solid heat, especially suitable for lung fever cough and swollen and sore gums.

This is the main effect of mountain bean root, because it has a good effect of clearing heat and detoxifying, so there are many folk home remedies and test prescriptions will use mountain bean root.

However, if you don't pay attention to the dose, it often causes poisoning. Because the root of mountain bean contains toxic ingredients, excessive consumption will cause poisoning reactions, and in severe cases, there is even a risk of death. Therefore, when you use it, you must be very careful, and the specific dose should not exceed 6 grams for each use.

There is only one species of parasitic plants, parasitic plants include crystal orchid, dodder seed, rootless vine, cistanche, lock yang, etc., and the vitality of parasitic plants is relatively strong, belonging to positive plants, this kind of plants are mostly parasitic on other plants or organisms to survive, the body contains less chlorophyll, can not supply nutrients by itself.

What are the parasitic plants.

Parasitic plants have strong vitality and belong to positive plants.

<> "Parasitic Plants"How parasitized.

We are more familiar with parasitism in the animal kingdom, but in the plant kingdom, parasitism is also widespread, and parasitic plants are often considered to be harmful to the host rather than beneficial. So, why do they parasitize? How is it parasitized?

In fact, the reason why parasitic plants want to parasitize other plants is also forced to survive. Due to the lack of sufficient chloroplasts, the root system or leaf organs of parasitic plants are degraded, and they lose their autotrophic ability, and cannot survive independently, so they have to attach to other plants. All parasitic plants have a special organ, which is the suckle.

Parasitic plants form a connection with the vascular tissues of the host through the sucker, and obtain nutrients, water and other substances required for growth from the host, resulting in a large loss of host nutrients, which in turn seriously affects the growth and reproduction of the host.

Parasitic plants are divided into many species, according to their relationship with the host, the characteristics of parasitism and the presence or absence of chlorophyll determine the degree of dependence of parasitic plants on the host, parasitic plants can be simply divided into all-parasitic plants and semi-parasitic plants.

There is no chlorophyll, can not assimilate carbon and nitrogen independently, no leaves or leaf degradation, no photosynthesis, its duct and sieve tube communicate with the host plant xylem duct and phloem sieve respectively, and completely rely on the host to provide nutrients are called holoparasitic plants, such as macrofloraceae, Snake family, and Liedon plants; Those that contain chlorophyll and can carry out photosynthesis are called semi-parasitic plants, such as mulberry parasitismaceae, dodder seeds, and sandalwood plants.

Under the same "eaves", "lazy" parasitic plants will cause a lot of harm to the host plant. The harmfulness of parasitic plants is mainly manifested in pathogenic effects. The holoparasitic pathogenic ability is strong, mainly parasitic on annual plants, which can cause the wilting of host plants, the decline of vitality, and in severe cases, cause a large number of deaths, which has a great impact on yield.

However, the semi-parasitism mainly parasitizes perennial woody plants, and has no obvious effect on the host in the early stage of parasitism, and causes poor growth and premature aging of the host when the population is larger in the later stage.

Studies have shown that under certain conditions, dodder seeds can help establish an "alliance" of insect resistance between different hosts. A single plant is often able to parasitize multiple neighboring hosts at the same time, thus connecting different hosts. It has been found that Cuscuta and its host have a wide range of material exchanges, and the "** line" like Cuscuta can allow different hosts to "exchange information" with each other and play the role of "communication channel".

When insects feed on a host, the host can produce a signal, which can not only trigger the insect resistance of the preded plants, but also transmit them to other host plants through the dodder seeds, which also enhances the insect resistance of these plants, so that different hosts can establish an "alliance" of insect resistance.
