Influence of «Bioecofunge-1» biocomposition on the growth and development of tomato plants (Solánum lycopérsicum L.)

Abstract

The problem of regulation of plant growth and development by physiologically active substances is one of the most pressing problems in modern biology. The widespread use of plant growth regulators (PGR) is an important factor in the effectiveness of crop cultivation technology. A significant achievement is revealing the role of biologically active compounds in the regulation of the most important vital functions of a plant organism, increasing resistance to adverse environmental factors (high and low temperature, drought, soil salinity, diseases, etc.), increasing the yield and quality of agricultural products. Plant growth stimulants are biologically active substances of natural origin that enhance the intensity of metabolic and growth processes in plants and increase crop productivity. A range of scientists has proved the practical application of Basidiomycota in agriculture, namely in creating biocompositions and preparations based on them to stimulate the growth and development of crop plants and protect them against diseases and pests. In this regard, research in the field of biologically active substances used in the production of tomatoes is a necessary step toward the creation of new technology elements for their cultivation — one of the realistic prospects of realizing this crop’s biological resources and productive resources potential. The study aimed to investigate the impact of biocomposition «Bioekofunhe-1» on tomato growth and development. The biocomposition was created based on Basidiomycota and plant components to stimulate productivity and protect against diseases of agricultural plants. Seeds of three varieties of tomatoes were selected for the experiment: Hibryd Tarasenko 6, Lahidnyi and Prydniprovskyi Rozhevyi. Laboratory tests about matching concentrations of biocomposition and determining their impact on the growth processes of tomatoes were done. We proved that the «Bioekofunhe-1» biocomposition stimulates tomato growth and development. We matched its optimal concentration (0.1%) for effects on the growth processes of seedlings of tomato varieties. The application of the «Bioekofunhe-1» biocomposition in that concentration provides increasing the aerial part length of tomato seedlings of all three varieties.
