| description |
Objective. To study the possibility of production of physiologically active substances by the as-sociation of micromycetes Trichoderma harzianum 128, which is used for enrichment composted substrates based on chicken litter. Methods. Microbiological, physiological, accumulative thin lay-er chromatography, high-performance liquid chromatography (HPLC / MS). Results. T. harzianum 128 produces a significant amount of physiologically active growth stimulanting substances. Soak-ing of corn seeds in the culture liquid of micromycetes association, diluted with water in 100– 10,000 times, provides a reliable growth stimulation of seedlings and indicates the absence of phy-totoxicity in microorganisms. The instrumental determination of the content of exogenous phyto-hormones in pre-purified and concentrated phytohormonal extracts shows a significant amount of auxins in a culture fluid — their total amount reaches 18.33 μg/g of dry biomass of the producer, and of cytokinins, in particular, isopentenylidenidine (5.6 μg/g of dry biomass) and zeatin (0.88 μg/g dry biomass). Association T. harzianum 128 in small quantities produces gibberellic acids — GK3 (0.34 μg/g dry biomass) and GK4 — 0.23 μg/g of dry biomass). Absorbent acid was also found in the culture fluid (5.3 μg/g dry biomass), but its amount is four times less than the cor-responding measures in the known strain T. viride F100001, which was used as a positive control in the studies. While the introduction of association T. harzianum 128 into the composted chicken litter substrate, the obtained compost shows high auxin and cytokinin activity. Conclusion. Phyto-hormones, which are produced by the micromycetes association of T. harzianum 128, can positively influence the growth and development of plants, play a protective role in adverse environmental conditions. After introduction of the investigated fungi association to a composted substrate on the basis of chicken litter it accumulates significant amounts of physiologically active substances of auxin and cytokinin action. Under these conditions compost acquires new qualitative features. |
