Influence of growth regulators on the formation and growth of adventive roots of houseplants

The article deals with the influence of growth regulators on the increase in the number and length of adventive roots of houseplants. Technologies for growing indoor plants include the use of biostimulants that have an effective effect on their growth and development. With the increasing influence of anthropogenic factors on the living conditions of city residents, the cultivation of indoor plants is relevant. Green cuttings are one of the most effective ways of vegetative propagation of plants. A laboratory experiment using growth regulators ("Epin" and "Zircon") showed the effectiveness of using different concentrations for the formation and increase in the length of adventive roots of houseplants (Episcia clove and Tradescantia belotsvetkovaya). The results of the study showed that the growth regulator "Zircon" (in a concentration of 0.5 %.) has an effective effect both on the formation of adventive (adventitious) roots, and on increasing their length of cultivated plants: episcia clove-flowered and tradescantia belotsvetkovaya). When using the growth regulator "Zircon": variant experiments 1 (concentration of the drug 1.0 %) and variant experiments 2 (concentration of the drug 0.5 %), there is an increase in the number of adventive roots in 2.6 and 4.1 times, compared to the control. In Tradescantia belotsvetkova, there is also an increase in the number of adventive roots by 2.8 and 3.8 times, compared with the control. The influence of the concentrations of the growth regulator of zircon for the epissia carnation is manifested in the intensity of the growth of the plant roots, expressed in an increase in their length by 3.2 and 4.8 times, compared with the control. Also for tradescantia white when using growth regulator "Zircon" in concentrations of 1.0 per cent (variant 6) and0.5 % (the version 7) has shown to increase the intensity of root growth at 3.4 and 4.8 times compared to control. It is possible to offer a growth regulator "Zircon" (in a concentration of 0.5 %) for practical use in strengthening the root formation of indoor plants during green cuttings.
