Auxins are an element of great importance for plants. It is a type of plant hormone that helps plant growth and development. Among its benefits we also find its contribution to the regulation of tropisms or organ abscission, causing a later fall of flowers, leaves and young fruits.
What are auxins?
The world of plant phytohormones is enormous and is composed of a great variety of components. Among them, auxins are one of the most important groups. Cell elongation and regulation of cell membrane permeability are some of their main functions, in addition to the crop growth discussed above.
A plant can obtain auxins in two ways. On the one hand, naturally. However, sometimes the amount produced by this method is insufficient. Therefore, products containing auxins are available to help the plant to have the right level of this phytohormone.
How they act in the plant and what they are used for
Auxins are synthesized in the parts of the plant where leaves and stems are born, that is, in the meristems at the apex of the stems, which we can distinguish as a small bulge. From that point they begin to move to other parts of the plant where they may be needed, although it has been shown that they are much more mobile towards the base than upwards, so it is common to find a higher concentration of auxins in the roots than, for example, in the flowers. However, their main benefit is always the same: the contribution to plant growth and development.
Types and nature
One of the best known auxins is indolacetic acid. This phytohormone belongs to the family of auxins of natural origin and can be found in marine algae, microalgae, fungi or bacteria. However, there are also auxins synthesized in a laboratory to help stimulate the growth of plants that need it most. In short, auxins can be classified as follows.
Synthetics
- 2,4-dichlorophenoxybutyllic acid (2,4-DB)
- 2,4,5-trichlorophenoxyacetic acid (2,4,5,-T)
- Indolbutyric acid (AIB)
- 2,4-dichlorophenoxyacetic acid (2,4-D)
- Naphthoxyacetic acid (NOA)
- Naphthaleneacetic acid (ANA)
Natural
One of the precursors of natural auxins are zinc and the amino acid tryptophan, so most of the natural auxins are derived from these elements. Among their main types we find:
- Indolbutyric acid (IBA). This auxin can be found both synthetically and naturally in small amounts in living organisms.
- Indole propionic acid (IPA)
- Phenyacetic acid
- Indoleacetic acid (IAA)
- 4-chloroindolacetic acid
Relation to Micro Carbon Technology
Huma Gro's technological process is based on the transformation of organic matter from leonardite using living elements such as algae and bacteria. These organisms naturally produce different phytohormones (such as auxins), which are an important part of the Micro Carbon Technology. During the biodigestion process, leonardite is slowly transformed into shorter carbon chains, increasing its content of functional groups, polyphenols and sugar-based radicals, antioxidants, amino acids and natural phytohormones (such as auxins and others). All of these are derived from digestion by these living organisms.
Huma Gro products growth promoters with auxin activators
At Agran Liquid Technology we have developed two products that will help you provide the auxins needed to stimulate the growth of your crops.
- Vitol. It is a promoter of vertical growth and fruit size increase. Thanks to Micro-Carbon TechnologyTM technology, it stimulates the natural production of auxins and other hormones that will improve crop yield. In addition, it also helps to adapt the plant to stress caused by aggressive environmental conditions.
- Breakout. This enhancer promotes the natural activation of hormones such as auxins, enhancing bud break, flowering and fruit set.
