Abstract The article presents the results of the research of LED light intensity influence on the stages of development and growth of containerized seedlings of Scots pine and European spruce growing in a closed system. We used three levels of light intensity: 109, 221 and 307 µmol/m2/s. A direct correlation between light intensity and the rate of phase onset was detected. The beginning of the phase of cotyledon opening occurred on day 12 for plants from the section with medium and high light intensity, and from day 13 for the section with low light intensity. The phase of bud emergence of an embryonic shoot actually begins the coniferous stage of development of pine and spruce seedlings. The first buds of an embryonic shoot in Scots pine began to appear on day 12, and in European spruce – on day 13. The phase of deployment of true needles runs almost parallel to the formation of buds of an embryonic shoot. The lag is 1 day for both Scots pine and European spruce. For both species, intensity of true needles unfurling is significantly higher at medium and high light intensity compared to low light intensity. Using a photoperiod of 13 hours leads to the establishment of apical buds in both pine and spruce. When the duration of photoperiod was increased by 1 hour, the growth processes were activated, which led to an increase in the height of seedlings within a month for pine by 43.4–67.3%, and by 5.2–28.4% for spruce.
