Growth regulating substances that can be applied to organic compounds of Orchids is not a nutrient, which in small amounts can support, inhibit and can either plant physiological processes.
Growth regulating substances in plants consists of Five groups; Auxin, Cytokinines, Gibberellins, Ethylene, and inhibitors with characteristic and different effects on physiological processes.
AUXIN
Auxin types commonly used in plant growth were : IAA ( Indole Acetic Acid ), NAA ( Naphtalene Acetic Acid ), IBA ( Indole Butyric Acid ).
Auxin are used to spur the formation of Callus, especially roots, somatic embryogenesis spur and spur the growth of shoots.
CYTOKININS
Goups of cytokinins that are often used are: Zeatin, BAP ( Benzyl AminoPuine ), Kinetin. Cytokines used to stimulate cell division, stimulate the formation of buds, side shoots and inhibits the multiplication of root formation.
GIBBERELLINS
Gibberellins were first discovered in the rice plant that grows lengthwise in JAPAN, then its compounds in the extracts and was named " GIBBERELLINS ". After a while it turns out similar compounds are also present in other plants but different from each other, so can get about 60 species Gibberellins. Among them is often used GA3 ( Giberellic Acid ). Gibberellins inhibit cell division and somatic embryo development, but it can stimulate cell elongation and the formation of xylem tissue, so that the plant becomes longer.
VITAMINS
Vitamins needs in Orchid plants are Thiamin ( Vitamin B! ), Pyridoxine ( Vitamin B6 ). Vitamins are generally located in the crops. Thiamin function is to accelerate cell division in roots.
AMINO ACIDS
Amino Acids found in many organic materials both animal and vegetable. Amino Acid content in the plants need are: Asparagine, Glycine, Methionine, Phenylalanine, Proline, Threonine, Alanine, Isoleucine, Lycine, Siren, Ammonium, Acetic Acid, Lacetic Acid, Glutamac Acid.
