The results of a laboratory experiment to study the influence of the microalgae Eustigmatos magnus (Ochrophyta) and cyanobacteria Nostoc sp. (Cyanobacteria) and their complexes for the growth and development of cucumber seedlings are presented. It was found that the original and diluted cultures of these photosynthetic microorganisms and their complexes have a stimulating effect both on the length and on the weight of cucumber seedlings. In the experiment with the initial cultures of algae and cyanobacteria, the maximum average length of shoots in the variant of the experiment with the Nostoc–Eustigmatos 3N:1E complex was recorded (179.18 mm); the maximum average mass of shoots – in the variant of the experiment with the Nostoc–Eustigmatos complex in a 1N:1E ratio (0.32 g). In the experiment with diluted cultures of algae and cyanobacteria, the maximum average length and mass of shoots in the variant of the experiment with the Nostoc–Eustigmatos 1N: 2E complex were noted (170.48 mm, 0.31 g). Phytoeffects varied from 11% to 167% along the length of seedlings, and from 10% to 94% according to the weight of seedlings. When using the original cultures of microalgae and cyanobacteria, the maximum phytoeffects were observed when using the Nostoc–Eustigmatos complex with a composition of 1N: 1E, when using diluted cultures, with a composition of 1N:2E. To increase the efficiency of using microalgae of the genus Eustigmatos and cyanobacteria of the genus Nostoc as stimulators of the growth of cucumbers, it is recommended to use algocyanobacterial complexes Nostoc–Eustigmatos.

Key words: microalgae; cyanobacteria; algocyanobacterial complexes; phytoeffect; cucumber culture
