Reproduction Vegetative

Vegetative propagation

Vegetative reproduction is an asexual method of reproduction in which a new individual is formed from part of the maternal organism.

During vegetative propagation, the formation of germ cells and fertilization do not occur. Instead, a new individual is formed from the somatic cells of the mother’s body, genetically identical to the parent.

There are several methods of vegetative propagation:

1. The division of the mother into parts from which new organisms grow (for example, the division of filamentous algae).

2. Budding is the formation on the body of the mother organism of the rudiments of new individuals - buds, which then bud and begin an independent life (in hydra, many plants).

3. Formation of shoots from dormant buds on roots, tubers, bulbs (potatoes, tulips).

4. Vegetative propagation using tendrils, rhizomes, root suckers (strawberries, wormwood).

5. Cuttings - rooting parts of plant stems and growing new individuals from them.

Thus, vegetative propagation is an important mode of asexual reproduction in which the offspring are genetically identical to the parent. This type of reproduction is widely used by plants, fungi, protozoa and some invertebrate animals.

Propagation Introduction One of the main questions for many home gardeners is plant propagation. This process allows you to prolong the existence of your green friend and leave some offspring for you, which will also benefit you in the future. The most effective type of reproduction is propagation by seeds, since under such conditions the child will have exactly the same genetic code as the parent. But there are plants whose propagation by seeds is impossible or difficult - and then vegetative propagation comes to the rescue. This type of reproduction is also suitable for animals, not only multicellular ones, but even unicellular ones. For example, single-celled organisms (amoebas) can also divide so that they undergo the process of vegetative reproduction. In our life, there are a large number of plant species that cannot be propagated by seeds and we have to resort to vegetative methods. The most common type of vegetative propagation is layering and grafting. You can conclude that in some plants reproduction has little to do with seeds at all and I understand that this is difficult to believe. For example, a snake does not have a reproductive system, while most spiders have reproductive organs made up of them. Although, of course, the simplest example of propagation using seeds is a garden-type plant - corn. In nature, all plants reproduce in different ways, and you might have encountered a situation where you had a flowering linden tree, which was unlikely to bring you more seeds for food - this would already be a method of vegetative reproduction.

Layering Root division is the so-called method of growing seedlings. You can also propagate your root shoots. After this method, you get shoots that completely copy all the characteristics of the parent bush, but are slightly smaller in size. Such rapid, peculiar and natural development is of interest for horticulture. Gardeners choose this method both for non-harvesting varieties of garden crops, as well as for medicinal, varietal and ornamental flowering ones. Throughout the day, cuttings passively accumulate microelements and water, and form strong roots at the tips of the root system. With the help of layering, you can quickly propagate broad-leaved shrubs - pear, grapes and viburnum. The root removal method is labor-intensive and requires certain dexterity and skill. With this kind of reproduction you will definitely need special tools. First you need to trim the seedling, clear it of leaves and place it in a one-centimeter hole
