Here is some information on plant hormones that I have used.
This miracle molecule, fulvic acid passes through plant's cell walls with ease. Fulvic acid acts like a claw or chelating agent attaching to minerals that would otherwise be rendered useless to plants. Essential nutrients vitamins and/or plant growth regulators (which plants may not be able to assimilate easily), will 'piggyback' on the fulvic acid to be transported to all cells that need them. This miracle molecule has incredible potential when used for soil enrichment in hydroponic applications and as a foliar spray.
When necessary, they act as "free-radical" scavengers, supply vital electrolytes, enhance and transport nutrients, catalyze enzyme reactions, increase assimilation, stimulate metabolism, chelate and change inorganic minerals into organically complex minerals, solubilize, energize and transport major and trace elements to the site of need, and demonstrate amazing capacity for electrochemical balance.
Fulvic acid is a natural mineral which has survived through the many years of evolution on Earth. It is one of the best and most basic minerals to encourage healthy plant growth. It has chemical properties that allow plants to absorb more nutrients and increases water storage capacity within the plant. Fulvic is so powerful that one fulvic molecule is capable of carrying 60 or more minerals and trace elements into plant cells. It also prolongs the time that essential nutrients remain in the plant cells and maximizes nutritional potential. Fulvic acid increases plant metabolism therefore it naturally increases growth.
One property of fulvic acid is its ability to assimilate with other minerals in the ground when it's a soluble state. It helps turn minerals into a more organic, usable product. When the minerals turn organic, they are more readily and easily absorbed by plant roots. Fulvic acid transmits immunity to all living things. It reacts to everything including living cells, plants, animals and even microscopic organisms.
Fulvic acid may be administered via foliar applications. It has a low molecular weight which facilitates penetration into plants. Nutrients can be quickly delivered to all sites within the plant, correcting deficiencies and restoring natural balance.
As soon as the first flower sites appear, apply fulvic acid as a foliar spray to increase the number of internodes, (flower sites a plant produces).
The most exciting discovery in glasshouse agriculture in recent years is the application of fulvic acid in hydroponic or soilles cultivation. Agricultural scientists have been aware of the benefits of soil applications of fulvic acid for many years. However, it was only recently discovered that fulvic acid could provide the same benefits to soilless crop production.
Adding fulvic acid to the nutrient solution once plants are established, around the second week, strengthens their immunities and increases their resistance to stress. Plants are not as susceptible to slight environmental changes in temperature or humidity. Fulvic acid will not compensate for poor hydroponic cultural practices however it does offer a buffer against minor inconsistencies
NFulvic acid helps plants deal with droughts and freezes better. Its Superior Chelating action is highly desired by hydroponic growers, it greatly improves the plants ability to absorb nutrients. It readily penetrates the cell walls of the plant, carrying nutrients and or plant growth hormones along with it when applied as a foliar spray.
Indole Acetic Acid
Indole acetic acid, also known as IAA is an Auxin. This colorless solid is a native plant compound, potent and the most important and active auxin. IAA has many different effects, as all auxins do, such as inducing cell elongation and cell division with all subsequent results for plant growth and development. On larger scale, IAA serves as signaling molecule necessary for development of plant organs and coordination of growth and helping plants find light.
- When combined with other plant hormones, it helps them function better. Such as IBA, NAA and BAP.
- Increase the growing season of some tuberous plants when applied late in the season.
Giberellic Acid (GA-3)
Gibberellic acid (actually a group of related substances called gibberellins) was discovered as a metabolic byproduct of the fungus Gibberella fujikuroi, which causes the stems of growing rice to elongate so rapidly the plant collapsed. Synthetic forms of gibberellic acid are available commercially.
Gibberellic acid (GA) is a very potent hormone whose natural occurrence in plants controls their development. Since GA regulates growth, applications of very low concentrations can have a profound effect. Timing is critical: too much GA may have an opposite effect from that desired; too little may require the plant to be repeatedly treated to sustain desired levels of GA.
Effects of Gibberellic Acid
Overcoming dormancy. Treatment with high concentrations of GA is effective in overcoming dormancy and causing rapid germination of seed. Concentrations of about 2 ppm can cause tubers to sprout earlier.
Premature flowering. If a plant is sufficiently developed, premature flowering may be induced by direct application of GA to young plants. This action is not sustained and treatment may have to be repeated. Formation of male flowers is generally promoted by concentrations of 10 to 200 ppm., female flowers by concentrations of 200 to 300 ppm. Concentrations of more than 600 ppm markedly suppresses initiation of both male and female flowers. Increased fruit set.
When there is difficulty with fruit set because of incomplete pollination, GA may be effectively used to increase fruit set. The resulting fruit maybe partially or entirely seedless. GA has increased the total yield in greenhouse tomato crops both as a result of increased fruit set and more rapid growth of the fruit.
Hybridizing. Pollination within self-incompatible clones and between closely related species may some times be forced by the application of GA and cytokinin to the blooms at the time of hand pollination.
Increased growth. GA applied near the terminal bud of trees may increase the rate of growth by stimulating more or less constant growth during the season.
Spraying fruit trees at full-blossom or when the blossoms begin to wither can offset the detrimental effects of frost.
Root formation. GA inhibits the formation of roots in cuttings.
Brassinolide is a Brassinosteroid, a plant steroid.
BRs (Brassinolide) have been shown to be involved in numerous plant processes:
- Promotion of cell expansion and cell elongation. Works with auxin to do so.
- It has an unclear role in cell division and cell wall regeneration.
- Promotion of vascular differentiation; BR signal transduction has been studied during vascular differentiation.
- Is necessary for pollen elongation for pollen tube formation.
- Acceleration of senescence in dying tissue cultured cells; delayed senescence in BR mutants supports that this action may be biologically relevant.
- Can provide some protection to plants during chilling and drought stress.
- Encourages new root growth.
Benzylaminopurine is a cytokinin. Cytokinins are compounds with a structure resembling adenine which promote cell division and have other similar functions to kinetin.
Kinetin was the first cytokinin discovered and so named due to the compounds ability to promote cytokinesis (cell division).
Though it is a natural compound, it's not made in plants and is therefore considered a "synthetic" cytokinin (meaning that the hormone is synthesized somewhere other than inside a plant).
The most common form of naturally occurring cytokinin in plants today is called zeatin which was isolated from corn (Zea mays).
A list of some of the known physiological effects caused by cytokinins are listed below. The response may vary depending on the type of plant species.
Stimulates cell division.
Causes growth of new branches, shoots, and buds.
Stimulates morphogenesis, (shoot initiation/bud formation), in tissue culture.
Stimulates the growth of lateral buds-release of apical dominance.
Stimulates leaf expansion resulting from cell enlargement.
May enhance stomatal opening in some species.
Promotes the conversion of etioplasts into chloroplasts via stimulation of chlorophyll synthesis.
