The influence of bioregulating adaptogens on the growth processes, development and decorative qualities of an orchid

Abstract At present, plant biostimulating adaptogens used in the process of growing a wide range cultivated plants are artificial analogs natural stimulants, chemical composition which contains phytohormones, amino acids and vitamin complex, enhance growth development root system by several times. The effectiveness these agents is explained creation mutually beneficial symbiosis mycelium mycorrhizal fungi plant, thereby providing roots orchid with biologically active elements: mineral salts, enzymes, hormones vitamins. Mycorrhizal fungi, turn, receive carbohydrates necessary for their development. Due to fact that indoor contain small amount regulators composition, synthetic productive orchid, determines relevance research carried out. article presents results experiments on effect Ribav-extra, Ecopin Epin-extra formation cuttings morphological features studied species dendrobium orchid. were propagated three ways: dividing bush, pseudobulbs cuttings. soaked 18 h before planting drug solutions at concentration 1 ml/10 L water. Also, vegetative sprayed twice biostimulants: phase regrowth first leaf two weeks later 0.5 obtained showed differences experimental variants terms onset phenological phases: beginning roots, leaves peduncles, as well flowering period. reaction treatment was revealed. In all variants, preparations stimulated system, apparatus, appearance peduncles. phenophase data tested occurred 7-28 days earlier comparison control variant (without use bioregulators). test regulator Ribav-extra promoted second (by 20-28 days). Ekopin turned out be most passive did not significantly affect rate plants. phenophases 1st began 3-5 than variant. peduncles age 3 years.
