hormones

Indole-3-acetic acid (IAA)

CAS No: 87-51-4

Specification: 99% TC

IAA is a plant hormone of wide-spectrum, belonging to the auxin family plant growth regulators. It is used as main ingredient in some commercial rooting products, in order to stimulate rooting of cuttings of herbaceous and woody crops and ornamentals.

Application Range:

Rice, Peanut, Cotton, Eggplant, Peach, Plum, Apple, Pine, Grape Mulberry, Poplar, Meta sequoia, Grewiaasiatica, Potato, sweet potato, Kiwi, Corn, Bean, Carrot, Melon, Watermelon, Tomato.

Indole-3-butyric acid (IBA)

CAS No: 133-32-4
Specification:98% TC

IBA is a plant hormone of the auxin family. It is used as main ingredient in several commercial rooting compounds. It also increases fruit set of crops and is also recommended when in vitro propagation is carried out, because when combined with cytokinins like kinetin, auxins like IBA give rise to masses of undifferentiated cells called callus.

Callus formation is often used as a first step in micropropagation processes, for the callus cells are used as starting point to form other tissues.

Application Range:

Cherry, Dianthus, Chrysanthemum, Jasmine, Peach, Magnolia, plum tree, Azalea, Rhododendron, Apple, Grape, Kiwi, Melon, Tea, Metasequoia, Poplar, Pine, etc.

1-Naphtaleneacetic acid (NAA)

CAS No: 86-87-3

Specification: 98% TC

Auxins induce development of phloem and xylem, also cell differentiation, as well as regeneration of the vascular tissues in plants. For this reason, it is widely used in micro propagation of crops. In cropping, auxins promote rooting, and are also required for fruit growth and development. NAA also increases fruit set and parthenocarpy in the absence of fertilization. Auxins also delay fruit senescence.
NAA is widely used in agriculture, plant nursery and forestry, to stimulate rooting in cuttings and improve setting in fruit, also to prevent pre-harvest drop.  NAA is often used in order to induce flowering in some crops, such as pineapple (caused by the auxin-induced production of ethylene). NAA may also be used to prevent sprout of potato tubers.

Application Range:

Wheat, Soybean, Beetroot, Tobacco, Cannabis, Cotton, Potato, Cabbage, Sugar Cane, Metasequoia, Mint, Rice, etc.

GA4 + GA7

CAS No GA4: 468-44-0
CAS No GA7: 510-75-8

Gibberellins accelerate vegetative shoot growth leading to larger plants. Also, cell division gets increased.

Effects:

– Generally reinforces apical dominance in the plant.
– Stimulates flowering without the necessary exposure to cold temperatures and/or specific requirements of daily lighting. For example, it has an efficient effect in solving the blooming of flowers at different times in the hybrid rice breeding.
– Increases fruiting. It stimulates early flowering and has the property of inducing parthenocarpic fruit set in some species, such as pears.
– Breaks seed dormancy. Accelerates the germination of some seeds.
– Breaks dormancy of the vegetative organs. Induces sprouting of bulbs and tubers.
Usually GA4 + GA7 is used to complement the action of Gibberellic acid (GA3). It acts as a nuance element in the parthenocarpy enforcement, because the use of GA3 alone causes unusual shapes in fruits.

Glycine-betaine

CAS No: 104-43-7

The glycine-betaine is an amino acid derivative that occurs in plants, specially under stress conditions. A well known role of this compound is to maintain the water content of cells being under osmotic stress, by lowering solute potential, i.e. implementing an osmotic adjustment.
More extensively, it plays an important role as a compatible solute in plants under various types of environmental stress, such as high levels of salts, drought, or high or low temperatures.
Plant species differ in their capacity to synthesize GB, and some plants, such as spinach and barley, accumulate relatively high levels of GB in their chloroplasts, while others, such as tobacco, do not synthesize this compound.

In most crops, the exogenous application of glycine betaine usually leads to an enhancement of resistance to stress conditions.
