“…An important advantage of fluorescent research methods is that they usually can detect changes in the photosynthetic apparatus in the early stages of the impact of one or another factor, even before the appearance of typical morphological changes [1,[4][5][6]. Establishing the relationship between fluorescent and physiological characteristics of plants is an important and urgent task.…”

It is shown that before sowing treatment of triticale seeds with the growth regulators epin and zir con resulted in an increase in the F 742 /F 686 ratio of the stationary fluorescence intensities of plant leaves at the wavelength bands of 742 and 686 nm corresponding to the maxima in the leaf fluorescence spectrum. Triticale under the treatment of seeds with growth regulators showed higher chlorophyll content, higher productivity, and higher indices of crop yield.

“…It is well established that �uorescence spectroscopy is an effective method for environmental monitoring and hydrographic measurements [33,34], characterization of benthic organisms [35], algal cells [36,37], corals [38] and higher plants [39][40][41][42][43][44][45][46], speci�cation of photosynthetic pigments [47][48][49], and other biological molecules [50,51]. Spectral methods were successfully employed for studying NOM in natural water [52][53][54][55][56][57][58][59], as well as commercial HS preparations [60][61][62][63].…”

The work is targeted to confirm participation of microscopic fungi in transformation of humus substances in aquatic environments. The research is focused on the spectroscopic study of the collection of fungal strains with different pigmentation of mycelium. Spectral properties of fungal metabolites were measured and compared to that of natural aquatic nonliving organic matter and commercial humus substances in aqueous solutions. The experiments revealed that the effect of microscopic fungi growing in the culture medium with added humate appeared as changes in the humic-type fluorescence: its characteristics became more similar to that of nonliving organic matter in natural waters than to original humate preparation. The experiments demonstrated degradation of coal-originated humate due to microbial activity into compounds of smaller molecular size and increased heterogeneity. We resume that transformation of humus substances by fungal cultures can be monitored and characterized using spectral measurements.
