Abstract
Pot experiments with seven agricultural crops were carried out in laboratory conditions to study the effect of fungal strains on their growth and development: soybean (Glycine max), barley (Hordeum vulgare), alfalfa (Medicago sativa), rapeseed (Brassica napus), safflower (Carthamus tinctorius), sweet clover (Melilotus officinalis), sainfoin (Onobrychis viciifolia). Five fungal strains with biotechnologically valuable properties were used: P. bilaiae Pb14, P. bilaiae C11, T. pinophilus T14, Aspergillus sp. D1 and B. bassiana T7. Inoculation with fungal strains increased theshoot length of seedlings by 14-33%, the root length by 13-29%, the shoot dry weight by 12-31%, the root dry weight by 15-30% compared to the controls.The application of fungal strains had a stimulating effect on the photosynthetic activity of plants by increasing the content of chlorophyll in the leaves of seedlings. There was an increase in the content of chlorophyll a by 8-16%, chlorophyll b - by 9-17%.
Highlights
One of the current trends in the development of sustainable agriculture is the microbial biotechnology
Plant growth-promoting fungi (PGPF) are a diverse group of nonpathogenic fungi that provide a complex of beneficial effects to their host plants
The interest in PGPF is associated with their possibility to increase the yield of agricultural crops by restoring soil fertility, improving germination, seedling vigor, plant growth, root morphogenesis, photosynthesis, and flowering through direct and/or indirect mechanisms.The main mechanisms of PGPF include solubilization and mineralization of
Summary
One of the current trends in the development of sustainable agriculture is the microbial biotechnology. The application of PGPF is one of the eco-friendly strategies of increasing crop production. The aim of this research was to study the influence of five fungal strains on the growth and development of seven agricultural crops
