What is apical dominance?

apical dominance is a phenomenon observed in plants in which the central stem becomes dominant, grow faster than other stems and excrete hormones that inhibit the growth of the stems under the terminal bud at the end of the apical stem. Many plants and trees show apical dominance, and fir are a classic example. The distinctive triangular shape of the company tree is the result of apical dominance, with a tree trunk is an apical stem.

There are a number of reasons why plants accept apical dominance. Pouring energy into the central stem can quickly reach height, increasing their approach to nutrients and also helps the competition of plants block. This phenomenon is also exposed in root systems where apical dominance leads to a long, very strong taaproot that keeps the plant firmly anchored in place, unlike the fibrous root system, which can unstable the plant in some soils. Hormonal auxin. If it is removedOr circulation is inhibited, other stems start to shoot and one can again be apical. Apical dominance can also be seen on branches; The branches that grow from the main stem suppress the growth of smaller branches from the stems along their length.

gardeners can handle the shape of plants by removing the terminal buds. What he does supports a bushy, growth habit of shrubs with a number of spreading branches, of which nothing becomes dominant. This appearance can be required for some trees and plants and gardeners can use pruning and other manipulative techniques to force plants to grow in a specific way. It is important to identify the terminal bud for removal if the goal is to create a shrub growth.

In the trees and plants that lack apical dominance, the tendency tends to take over a more chaotic and less conf.s controlled appearance. The branches are extending and many of them will have withA matter of length or very similar because no stem is dominant. Tomatoes are an example of a plant that does not show apical dominance, with all the stems growing more or less the same degree. These plants tend to grow rather than up, sometimes require support for their spreading branches because they are designed to eliminate competition by expanding and creating everything.
