Plant Growth Regulators

Plant hormones (also known as phytohormones) are chemicals that regulate plant growth. Hormones regulate cellular processes in targeted cells locally and, when moved to other locations, in other locations of the plant. Hormones also determine the formation of flowers, stems, leaves, the shedding of leaves, and the development and ripening of fruit. Learn more: What are Plant Growth Regulators?

    24-Epibrassinolide (EBL) 90% – Brassinosteroid PGR Kits

    $5.00$374.00

    Brassinolide is a natural steroid that promotes cell elongation and division in plants. In 1979, M. D. Grove and colleagues isolated it from Brassica napus (rapeseed) pollen and characterized it as the first Brassinosteroid Class plant growth regulator phytohormone.

    BRs have been shown to be involved in numerous plant processes:
    -Promotion of cell expansion and cell elongation; works with auxin to do so. 
    -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, flooding, drought and salt stress.

    Benzylaminopurine (6BA) 98.7% – Cytokinin B PGR Kits

    $4.00$425.00 $4.00$350.00

    Benzylaminopurine is the most popular Cytokinin class plant growth regulator (PGR) hormone in the world. Its uses are diverse and widely documented. Common uses include branching stimulation, flower boosting and increased fruit set. One example is when you “pinch” the apical meristem (main shoot) of a seedling it forces it to drive its growth outwards via the leaf node auxiliary/lateral meristems. While the plant has no choice but do this, its actually this process where the plant produces cytokinins in response to the damage, and this over-balancing of the auxin/cytokinin/gibberellin chemical equation then signals the lateral meristems to actually grow. Typically at this stage of growth the young plant is in auxin-driven competitive mode expecting to need to grow straight up to ensure reaching sunlight (imagine a field of weeds). On humans there is an obscure history in regrowing hair.

    “In greenhouse and laboratory experiments, a plant bioregulator 2-diethylaminoethyl-3,4-dichlorophenylether (DCPTA) appears to have the potential for biochemical manipulation of plant growth. As compared with control plants, photosynthesis of DGPTA-treated plants was increased about 21%, and biomass was almost doubled. Moreover, DCPTA-treated plants had earlier flowering and more squares and bolls than did the control plants. Most noteworthy was the 36% increase in number of nodes: control plants averaged 10.5 nodes, whereas, DCPTA-treated plants had an average of 16.5 nodes.” -Source

    A new mid-summer addition. A proper guide is on the way…

    Another new vigor booster that operates via different mechanisms than Atonik, Brassinolide, Chitosan or Salicylic Acid.  This unique plant growth regulator boosts the effects of many other key aspects of vital plant chemistry. Perhaps the best example of beneficial phytochemistry augmentations is the maximization of photosynthesis efficiency.

    It can be compounded with micronutrinet fertilizer formulas to increase the utilization ratio of the fertilizer by about 30%, much better than any other fertilizer synergists. Likewise, it can be compounded with many kinds of germicides and insecticides to increase the effects of the agrochemicals significantly, and it has been proven that DA-6 has detoxification to many kinds of herbicides. Mixed with the herbicides, DA-6 can make the plants revive
    quickly without reducing the effects of the herbicide.

    Forchlorfenuron (CPPU) 1%SP – Water Soluble Cytokinin Kits

    $5.00$195.00

    Forchlorfenuron (CPPU) is a Cytokinin class plant growth regulator phytohormone. It has been approved for use on kiwi fruit & grapes in the U.S.A., as combined with Gibberellic Acid generate the swollen seedless fruits the world over enjoys. It also provides such benefits to Loquat fruits, a house favorite, although Loquats short shelf-life still prevents commercial exploitation. In 2011, CPPU was made somewhat famous for causing China’s “exploding watermelons“,  after being used too late in season coupled by monsoon like rain conditions.

    Absorbed by leaves, stem, cotyledon and germinated seeds, Forchlorfenuron (CPPU) promotes cell division, differentiation and development; induces budding of callus, and controls apical dominance; breaks dormancy of lateral buds and promotes germination; delays aging process and maintains chlorophyll in excised leaves; regulates the transport of nutrients; promotes fruit formation, etc. Used to increase the size of kiwifruit, table grapes and peaches; promote fruit set in melons, pumpkins and cucumbers; promote branching in apples; and increase yield in potatoes, rice and wheat.

    Gibberellic Acid (GA3) 20% TABLETS – Water Soluble

    $300.00$995.00

    Gibberellins have a number of effects on plant development. They can stimulate rapid stem and root growth, induce mitotic division in the leaves of some plants, and increase seed germination rate. Gibberellin A3 (GA3) is the most popular gibberellin, with the most ideal wide ranging effectiveness in the world. The product form of this naturally occurring PGR is organically synthesized via fungus much like antibiotics. GA3, amongst at least 126 other gibberellin class phytohormones, are produced in virtually every plant in the world (as well as many fungi & bacteria). Therefore, it isn’t beyond reason that we eat them everyday even when concerning truly organically produced vegetables. It’s very popularly used for seed germination to achieve both maximum possible sprouting times with maximum germination rates. This chem is essential for rare & expensive sorts of seeds, especially those that typically takes months to sprout. The effect it forces is cell elongation, which typically causes the cell stretching required for a seed to burst out of its shell (this is the natural process most seeds rely on to sprout). Spraying GA3 onto actual plants will cause the same elongating effects, so its important to balance this equation with auxins & cytokinins, where when balanced (“Trifecta”), makes for explosive growth potential. Other uses, for certain plants, is to force female flower development, which produces pollen that will only result in feminized seeds.

    SEEDLESS GRAPE PRODUCTION NOTICE: Now that we’re stocking Forchlorfenuron (CPPU), and have been researching it, it turns out that GA3 has been stealing all the thunder by GA3 vendors giving it all the credit when proper seedless grape production also uses uses CPPU as an important synergist.

    IAA is predominantly produced in cells of the apex (bud) and very young leaves of a plant. Plants can synthesize IAA by several independent biosynthetic pathways. Four of them start from tryptophan, but there is also a biosynthetic pathway independent of tryptophan. Plants mainly produce IAA from tryptophan through indole-3-pyruvic acid. IAA is also produced from tryptophan through indole-3-acetaldoxime in Arabidopsis. 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 a larger scale, IAA serves as signaling molecule necessary for development of plant organs and coordination of growth.
