what three types of stems may be used for vegetative propagation

Natural vegetative propagation occurs by means of roots, underground stems, subaerial stems, aerial shoots, leaves and bulbils. Artificial vegetative propagation occurs by use of special vegetative parts such as root tubers, corm, parts of rhizome etc., or by cutting, layering, grafting and bud grafting. Q2.

Full Answer

What is an example of vegetative propagation in plants?

Vegetative plant structures that arise from plant stems include rhizomes, runners, bulbs, tubers, and corms. Tubers can also stretch from roots. Plantlets emerge from plant leaves. Vegetative propagation may occur naturally through the development of rhizomes.

What types of plants can be propagated by cuttings?

Many types of plants, both woody and herbaceous, are frequently propagated by cuttings. A cutting is a vegetative plant part which is severed from the parent plant in order to regenerate itself, thereby forming a whole new plant. Take cuttings with a sharp blade to reduce injury to the parent plant.

What are the vegetative plant structures arising from stem?

What are the different types of stem cuttings?

Types of Stem Cuttings. The four main types of stem cuttings are herbaceous, softwood, semi-hardwood, and hardwood. These terms reflect the growth stage of the stock plant, which is one of the most important factors influencing whether or not cuttings will root.

What three types of stems can be used for vegetative propagation?

Natural vegetative propagation occurs when an axillary bud grows into a lateral shoot and develops its own roots (also known as adventitious roots). Plant structures allowing natural vegetative propagation include bulbs, rhizomes, stolons and tubers.

What are the 3 types of propagation?

Cuttings involve rooting a severed piece of the parent plant; layering involves rooting a part of the parent and then severing it; and budding and grafting is joining two plant parts from different varieties.

What is stem in vegetative propagation?

Vegetative propagation occurs through stems when new plants arise from the nodes. This is where buds are formed, which grow into new plants. Stems that grow horizontally on the ground are called runners.

What are the 2 types of plant propagation?

There are two primary forms of plant propagation: sexual and asexual. In nature, propagation of plants most often involves sexual reproduction, or the production of viable seeds. When exposed to proper environmental conditions, these seeds germinate and grow into mature, reproductive plants.

Which plants are propagated by stem cutting?

The plants like Rose, Bougainvillea, Chrysanthemum, Grapes, Sugarcane, Bananas and Cactus are commonly propagated by cutting. Starting new plants from stem cuttings is a very simple way of propagation, though it does require a bit more time and attention than other propagation methods.

Is roots used in vegetative propagation?

Plants use their leaves, roots, and stems for vegetative propagation, which is an asexual method of reproduction.

Why do we use vegetative propagation in plants?

Vegetative propagation is often used when the crop plants either do not produce seeds or when the seeds produced are not viable or are of long dormancy. The method relies on the use of pieces of vegetative plant parts such as stems, leaves, or roots to perpetuate the parent plants.

What is the types of propagation?

There are two general types of propagation: sexual and asexual.

What is the term for the stem of a plant that is bent to the ground and covered with soil?

Layering. In this, the stem of the plant is bent to the ground and covered with soil. Adventitious roots emerge from the plant parts covered with the soil. This attached stem with developing roots is known as a layer.

What is artificial vegetative reproduction?

Artificial Vegetative Propagation. This is a type of vegetative reproduction carried out by humans on the fields and laboratories. The most common types of vegetative reproduction occurring artificially include:

What is grafting in plants?

Grafting. In this, the cutting from some other plant is attached to the stem of plant rooted in the ground. The tissues of the graft become integrated with the tissues of the rooted plant and develop as a single plant over time.

Why are plant cells cultured?

In this, the plant cells from different parts of a plant are cultured in the laboratory to develop a new plant. This technique is helpful in increasing the number of rare and endangered plant species that are unable to grow under natural conditions.

What are the structures of vegetative propagation?

Vegetative propagation occurs through vegetative plant structures. In non-vascular plants, the vegetative reproductive structures are gemmae and spores whereas, in vascular plants, the roots, stems, leaves, and nodes are the vegetative propagation structures. Also, we have learned about the meristem tissue in plants. This tissue helps in the vegetative propagation. It has undifferentiated cells which divide. As a result, it paves the way for the growth of the plant. Also, from the meristems, specialized permanent tissues are formed.

How does vegetative propagation occur?

Vegetative propagation occurs through stems when new plants arise from the nodes. This is where buds are formed, which grow into new plants. Stems that grow horizontally on the ground are called runners. As these runners grow, buds form at the nodes, which later develop the roots and shoots, resulting in the formation of a new plant. Example – Cyanodon; Mint etc.

Why do new plants grow from older plants?

Because new plants can grow from older plants using vegetative propagation methods such as grafting and budding. It is a form of asexual reproduction seen in plants. This process involves only a single plant and the offspring that arises is identical, both genetically and morphologically, to the parent plant.

What is the process of propagation of plants?

Vegetative Propagation by Roots. In this process, new plants grow out of the modified roots called tubers. In fact, in some plant species, roots develop adventitious buds. These buds grow and form new plants/sprouts under the right conditions . For example, Sweet potato and Dahlia.

What plants have buds coming out of the leaves?

Plants like Bryophyllum, Begonia etc., have adventitious buds coming out from the notches of the leaves. These buds develop into new plants.

What is grafting in plants?

In grafting, we use two closely related plants to produce a new plant that has the desired, combined traits of both the parent plants. One plant is the stock, of which we take the root system and the other is the Scion, of which we use the shoot system. In this method of artificial vegetative propagation, we attach the scion to the stock of the second plant. In general, we use grafting for a variety of plants such as roses, apples, avocado etc.

What are some examples of bulbs?

Within the bulb lies the organ for vegetative propagation such as the central shoot that grows into a new plant. Bulbs have a bud surrounded by layers of fleshy leaves. A few examples include Onions, Garlic, and Tulips etc.

What are the two methods of vegetative propagation? Ans: The two methods of vegetative propagation are natural and artificial.

What is the process of growing plants?

In flowering plants, the roots, stem and leaves also help in reproduction. This process is called Vegetative Propagation in Plants. This method can be used to grow genetically and morphologically identical offspring from a parent plant. It is used commercially by gardeners to grow more plants in a shorter period.

What is artificial method?

In contrast, artificial methods are human-created processes that help in the propagation of new plants. The artificial methods of vegetative propagation like cutting, grafting, layering, and tissue culture are generally used by gardeners or farmers to get an improved crop with a high growth rate.

What are some examples of corms?

The corms separate from each other and form new plants. Examples: Gladiolus, Crocus, Crocosmia, etc. Fig: Vegetative Propagation by Corm. f) Bulb: It is a short stem that has fleshy leaves or leaf bases. The stem is reduced to form a disc-like base, also known as a basal plate.

What is the most common method of propagation of ornamental plants?

Introduction. Propagation by stem cuttings is the most commonly used method to propagate many woody ornamental plants. Stem cuttings of many favorite shrubs are quite easy to root. Typically, stem cuttings of tree species are more difficult to root. However, cuttings from trees such as crape myrtles, some elms, and birches can be rooted.

What are the different types of stem cuttings?

Types of Stem Cuttings. The four main types of stem cuttings are herbaceous, softwood, semi-hardwood, and hardwood. These terms reflect the growth stage of the stock plant, which is one of the most important factors influencing whether or not cuttings will root. Calendar dates are useful only as guidelines.

How to treat cuttings?

Treating cuttings with root-promoting compounds can be a valuable tool in stimulating rooting of some plants that might otherwise be difficult to root. Prevent possible contamination of the entire supply of rooting hormone by putting some in a separate container before treating cuttings. Any material that remains after treatment should be discarded and not returned to the original container. Be sure to tap the cuttings to remove excess hormone when using a powder formulation.

What are some examples of hardwood cuttings?

Examples of plants propagated at the hardwood stage include forsythia, privet, fig, grape, and spirea. The three types of hardwood cuttings are straight, mallet, and heel ( Figure 3 ).

What are SW cuttings made of?

SW. Herbaceous cuttings are made from non-woody, herbaceous plants such as coleus, chrysanthemums, and dahlia. A 3- to 5-inch piece of stem is cut from the parent plant. The leaves on the lower one-third to one-half of the stem are removed. A high percentage of the cuttings root, and they do so quickly.

How to keep a pot humid?

Maintain high humidity by covering the pot with a bottomless milk jug or by placing the pot into a clear plastic bag. Cuttings can also be placed in plastic trays covered with clear plastic stretched over a wire frame ( Figure 2 ). Trays must have holes in the bottoms for drainage.

When do you take cuttings from a broadleaf shrub?

Hardwood cuttings are taken from dormant, mature stems in late fall, winter, or early spring. Plants generally are fully dormant with no obvious signs of active growth. The wood is firm and does not bend easily.

Why do stems form roots?

This method of vegetative propagation, called layering, promotes a high success rate because it prevents the water stress and carbohydrate shortage that plague cuttings.

When to take stem cuttings?

Some can be taken at any time of the year, but stem cuttings of many woody plants must be taken in the fall or in the dormant season.

Why is it important to have continuous water supply for seed germination?

Even though seeds have great absorbing power due to the nature of the seed coat, the amount of available water in the substrate affects the uptake of water. An adequate, continuous supply of water is important to ensure germination. Once the germination process has begun, a dry period can cause the death of the embryo.

How long before transplanting seeds?

The proper time for sowing seeds for transplants depends upon when plants may safely be moved out-of-doors in your area. This period may range from 4 to 12 weeks prior to transplanting, depending upon the speed of germination, the rate of growth, and the cultural conditions provided. A common mistake is to sow the seeds too early and then attempt to hold the seedlings back under poor light or improper temperature ranges. This usually results in tall, weak, spindly plants which do not perform well in the garden.

How to stimulate seed germination?

Light is known to stimulate or to inhibit germination of some types of seed. The light reaction involved here is a complex process. Some crops which have a requirement for light to assist seed germination are ageratum, begonia, browallia, impatiens, lettuce, and petunia. Conversely, peas, beans, calendula, centaurea, annual phlox, verbena, and vinca will germinate best in the dark. Other plants are not specific at all. Seed catalogs and seed packets often list germination or cultural tips for individual varieties. When sowing light-requiring seed, do as nature does, and leave them on the soil surface. If they are covered at all, cover them lightly with fine peat moss or fine vermiculite. These two materials, if not applied too heavily, will permit some light to reach the seed and will not limit germination. When starting seed in the home, supplemental light can be provided by fluorescent fixtures suspended 6 to 12 inches above the seeds for 16 hours a day. High intensity lights will provide more light over the course of the day and will enhance the quality of seedlings. These lights cost more than the common shop lights, but are often worth the investment if you plan on growing plants indoors.

What temperature should tomato seeds be germination?

For example, tomato seed has a minimum germination temperature of 50 degrees F. and a maximum temperature of 95 degrees, but an optimum germination temperature of about 80 degrees. Where germination temperatures are listed, they are usually the optimum temperatures unless otherwise specified.

What is the rootstock of a plant?

It consists of a piece of shoot with dormant buds that will produce the stem and branches. The rootstock, or stock, provides the new plant’s root system and sometimes the lower part of the stem. The cambium is a layer of cells located between the wood and bark of a stem from which new bark and wood cells originate.
