Abstract
This paper presents the results obtained from the research realized in controlled environmental conditions in a horizontal greenhouse where seedlings from varieties of tomato lines in the process of testing for approval in Romania were used. The research was carried out in a three-factorial experimental scheme, in which were taken into consideration as variation factors: three cultivars of tomatoes, 3 colors of light emitted by the LED bulbs and 3 intervals of time (15, 30 and 45 minutes/day) for plant exposure to the monochromatic additional light treatment. Biometric measurements were made on the height and diameter of the stems and assessments of seedling weight, as well as analyzes on nutrient composition, accumulated after three months of cultivation in the greenhouse. The results obtained are within the limits mentioned by the specialized literature for the best seedlings for the tested varieties of tomatoes.
