How to speed up lignification of woody plants?

Strengthen light, increase phosphorus, potassium, magnesium and boron fertilizers, and increase the temperature of the production environment. These factors can speed up woody plants.

of lignification.

A moderate amount of water retention can speed up lignification.

Question 1: What does lignification mean? :

The cell wall is hardened and strengthened by the deposition of lignin (a polymer made up of a derivative unit of phenylpropane) produced by the cell, which increases the plant's ability to support gravity, and the ligylin cells inside the trunk are the result of lignification.

Question 2: What does herbaceous plant mean Herbaceous plant is a general term for a class of plants, but it is not a strict concept in the classification of botanical disciplines. Usually refers to those plants whose stems and branches are not lignified, and most of them are.

There are also perennial plants. Such as chrysanthemum, orchid, lotus, water lily, junzi orchid, allium orchid, rice, onion, garlic and so on.

Question 3: What kind of plant is this, lignified rhizomes. 50 points Meadowsweet (Spiraea salicifolia L.).), also known as horse pee, grasshopper grass, grasshopper tip, etc., belongs to the order Rosaceae, Rosaceae erect shrubs, up to 2 meters.

Problem 4: Lignification of herbaceous plants 1) Yes, this is a normal phenomenon.

2) However, this phenomenon indicates that its offering may not be as good as the previous branches, and if the surrounding air is humid, you will gradually see aerial roots grow on its lignified top.

3) It is recommended that when you reach the beginning of spring, cut new shoots into pots and gradually give up the old roots.

4) In addition, the soil should be loosened frequently, the soil should be kept moist, and the speed of root lignification will be slowed down.

Question 5: What does the succulent plant mean Generally [Ji xx] means that this plant is very similar to xx, but it is a miniature version (it looks alike, not necessarily a plant of the same family, for example, Xingmei is a genus Pachyphyllus, but Ji Xingmei is a sedum).

Jihua: It is manifested that the plant is smaller than normal and does not grow large.

Swelling: Manifested as an increase in leaf fattening.

Lignification: The encyclopedia explains that the cell wall becomes hard and firm due to the deposition of lignin produced by the cells, increasing the plant's ability to support gravity, and the xylin cells inside the trunk are the result of lignification.

XX brocade is a color variation of XX, a bit like albinism, which is generally due to gene mutation or incomplete gene expression, resulting in a lack of chlorophyll in the leaves. Therefore, the Jinhua plant grows relatively slowly, and the whole brocade (that is, the whole plant is whitened) basically cannot live. But there are some very special cases:

One branch has a full brocade, but the others are not. In this way, it is possible for the branches of Quanjin to survive on the nutrients provided by other branches, which is valuable

Question 6: How to count the stems of succulents as lignification, send a picture The stem becomes brown, the skin is hard, and it is not easy to break is lignified.

A: This is normal. Many herbaceous plants, especially perennial herbaceous plants, have the phenomenon of lignification, that is, the young shoots are herbaceous, and the old stems are woody, such as periwinkle, Shangao Henghu bean, pepper, yam, etc.

Lignification does not affect its normal growth, but it is a more overwinterable form of cell structure in the evolutionary process.

（lignification）

Gao Rongfu, Wang Rui).

The process by which the cell wall of a plant is invaded with lignin. In vascular plants, cells are lignified to varying degrees, and lignin becomes an indispensable structural substance in plants. Lignin has the effect of enhancing cell wall firmness and binding fibers.

During the growth of higher plants, lignin is constantly deposited in the cell wall. From the primary wall to the secondary wall, the more lignin accumulates, the higher the degree of lignification. The viability of cells decreases during lignification, and highly lignified cells, protoplasm disappears into dead cells, such as ducts, tracheids, and fibroblasts.

The structure of lignin is more complex, and the structure of lignin is different in different plants. gymnosperms are mainly composed of concedar alcohol; Dicotyledons are made up of callus and eugenol. These compounds are derivatives of phenylpropyl groups, which are first subjected to the lysis of ammonia by phenylalanine to produce cinnamic acid.

Cinnamic acid is hydroxylated and methylated to be converted into related compounds, and cinnamic acid-derived compounds produce cinnamic acid Coenzyme A, which is reduced to aldehydes by NADPH and then to related alcohols. These monolignols are first oxidized by their phenolic hydroxyl groups, and this oxidation process involves the participation of peroxidase and hydrogen peroxide to produce unstable phenolic oxygen radicals, which are coupled to form dilignol, which are further oxidized and can be converted into oligomeric intermediate products, and then gradually polymerized and generated lignin with complex structure. Peroxidase plays an important role in this, and a variety of peroxidase isoenzymes are present in the cell wall and protoplasts.

It can catalyze the synthesis of lignin-like substances from coumarol and coniferol in vitro. The synthesis of lignin is regulated by many aspects, including the ** of the precursor, the transport of the precursor into the cell wall, and the polymerization reaction of lignin. At the same time, it is also regulated by hormones, such as kitin, which can cause lignification of cultured tobacco cells in the presence of kitin.

Ethylene also promotes the synthesis of lignin.

The formation of wood is related to the synthesis of lignin, such as the early wood of Robinia pseudoacacia and poplar is mainly callus lignin, while the latewood is mainly eugenol. The formation of heartwood and separation is also related to lignification. The degree of lignification of tissues is somehow related to disease resistance and cold resistance.

First, the effect is violent.

1.After more than one year of propagation, the fleshy roots begin to dry up, and lignified branches may appear. The stems turn brown and are hard to the touch, which is also normal, not black rot.

The process of lignification is the gradual deposition of lignin produced within the cell. After lignification, the stems and roots will be thicker, which can guarantee that they will not break, and can support the upper part that gradually becomes heavier. 2.

After lignification, the cell wall is not elastic, and the cells inside do not absorb water and swell, avoiding overgrowth in the later stage.

2. Acceleration method.

1.More sun: The fleshy roots are lignified, which has many benefits and is conducive to the formation of old piles.

If you want to promote lignification of the roots as soon as possible, you need to get more sunlight and ensure good light. Fleshy ones that lack sunlight are difficult to lignify. However, summer is special, the sun intensity is strong, and it cannot be exposed.

2.Nitrogen fertilizer reduction: Fertilizer should be applied reasonably during the growth process.

If the soil is rich in nitrogen, it will affect the synthesis of acorn. Therefore, in order to promote lignification of the root system as soon as possible, it is necessary to reduce the application of nitrogen fertilizer.

Lignification: The cell wall becomes hard and firm due to the deposition of the polymer composed of the derivative unit of lignin (phenylpropane) produced by the cell, which increases the plant's ability to support gravity, and the xylin cells inside the trunk are the result of lignification.
