【 摘 要 】

The aim of the research was to study the influence of exometabolites of the fungus Penicillium sp. 65 on triticale plants (Ingen 93 variety, developed and homologated at the Institute of Genetics and Plant Physiology). Field experiments were conducted with 1 control and 3 experimental variants, each variant having an area of 3 m 2, sown with 500 triticale seeds (5 rows and 100 seeds per row). Before sowing the seeds were treated with exometabolite solutions in the following concentrations: 1:100; 1:300; 1:500. During harvesting 20 plants per variant were sampled and the following indices were determined: plant height, number of grain yielding spikes per plant, length of the main spike and obtained yield compared to the control variant. Experimental data showed the stimulatory effect of the exometabolites of the fungus Penicillium sp. 65 on triticale plants. An increase in the average length of the roots by 42.3% and their gross weight by 32.9%, as compared with the control variant, was recorded. To a lesser extent the exometabolites stimulate the increase of length and gross weight of seedlings (12.7% and 37.5% respectively). The number of grain yielding spikes per plant increased by 55.2% and the yield – by 32% in the variant where seeds were treated with exometabolite solution in concentration of 1:500.
