The experiment was carried out as factorial arrangements in completely randomized design with three replications. The results showed that most of the studied characteristics of transplants were affected by cultivar × light quality interaction. The tallest transplant height (16.63 cm) was observed in cv. Pamela under R, and the shortest (6.09 cm) in cv. Valouro under RB. The highest stem diameter (3.97 mm) belonged to cv. Karoon under RB, and the lowest stem diameter (2.02 mm) was measured in cv. Valauro under FT. The greatest leaf dry weight (0.27 g) was observed in cv. Karoon under RB, and the lowest (0.22 g) in cv. Valouro under R. The highest root dry weight (0.102 g) belonged to cv. Pamela under RB, and the least (0.02 g) in cv. Valouro under FT. In conclusion, blue (B) and Red- Blue (RB) lights can be used for producing tomato transplant.
