The intensity of growth of periodic culture microalgae Dunaliella viridis, the protein, triacylglycerides, β-carotene contents in its cells within a calendar year in case of standard constant cultivation conditions (constant light exposure, temperature, structure of environment etc.) were investigated. It was revealed that despite of constant cultivation conditions intensity of growth, the protein, triacylglycerides, β-carotene contents were characterized by seasonal variability. Negative correlation between intensity of growth of culture of microalgae and absolute values of the solar spots area (electromagnetic radiation of the Sun) and Volf’s numbers (corpuscular radiation of the Sun) is revealed. Dependence of the protein, triacylglycerides, β-carotene contents upon heliophysics factors absolute values had both linear and U-shaped character. Biotropic effects ambiguity of heliophysics factors can specify change dominating biotropic factors during growth of microalgae D. viridis (principle PDF).
