• Root exudates
• Unicellular alga
• Geliophysic factors and variability of cell cultures
• Biological activity of plant and fungal exudates

Plant root exudates (wheat, barley).

Activity of root exudation and composition of root exudates as index of the functional state of root and of the whole plants. The influence of the seed aging, conditions of growth, different chemical pollutants on root exudation activity. The root exudation and resistance of the plants to different pollutants.

Border cells of wheat and barley.

The functional state of the border cells and activity of root exudation. The role of border cells for forming of resistance to different pollutants.

Cultivation conditions, culture productivity and alga biomass composition

Change of physical parameters of cultivation
- temperature
- illumination
- rate of mixing
Modification of culture medium
- ethanol
- Fe, Cu
- water extracts of humus
- blood serum
- change of salt concentration.

Biological rhythms in culture of the unicellular àlgae.

The frequency of the passages and functional activity of the cells. Variability of integral parameters in cultures of unicellular algae and fluctuations of heliophysical factors. Using of attractors for analysis of chaotic fluctuations of integral parameters in cultures of unicellular algae.

Exudates of Lentinula edodes activity
