The study of fortification lilac plants obtained in vitro was achieved by organizing a bifactorial experience, factors influence was the genotype and culture substrate. Genotype was represented by two cultivars of Syringa vulgaris species: Mme Lemoine and Sensation. Two culture substrates were tested: mixture of manure, ground leaves, peat and sand (2:2:2:1) and peat Danmuld (pH = 5.5, particle size 0–20 mm). From the results recorded in the four years of experimentation, it is clear that the largest increases in plants height has registered Mme Lemoine cultivar, between 9.14 cm in the first year and 45.80, in the fourth year of fortification, the substrate composed of peat Danmuld. The capacity of suckers, better efficiency to registered cultivar Sensation, between 1.77 (first year) and 6.1 suckers/plant (fourth year), when grown on the substrate compound from a mixture of manure, ground leaves, peat and sand (2:2:2:1).
