The study presents data on the partial results of in vitro initiation for two varieties of Acer platanoides: 'Globosum ' and 'Crimson King'. During the initiation phase, Acer platanoides 'Globosum' showed the best initiation percentage, using the next nutrient composition: MS macroelements, MS microelements, MS vitamins, auxins/cytokines 0,2:1 mg/l, while Acer platanoides 'Crimson King ' variety recorded the best results on the nutrient medium with a different composition: MS macroelements, MS microelements, LF vitamins and auxins/ cytokine0,4:1,2 mg/l.

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).

There were used explants from the initiation phase and passed on the multiplication nutrient media. The nutrient media tested were MS, DKW and WPM and each had a different content of growth hormones. In order to determine the multiplication rate, was tested the influence of zeatin and thidiazuron, in concentration of 1.5 mg/l, on a constant level of indole-butyric acid (0.5 mg/l). In the growing chamber were a constant temperature and a photoperiod of 14 hours light/24 hours, at a luminosity of 2500 lux. From the observations and registered data was determined the multiplication rate (microshoots/explant) for the four genotypes.

Acer palmatum 'Dissectum Atropurpureum '- the Japanese maple – is a base branched shrub or with short crook trunk. The shoots are hairless and red. The flowers, situated in small corymbs, appear once with the leaves (Posedaru E.A., 2005). The species itself is grown from seed. Only a few strong-growing cultivars are commercially propagated from cuttings. Plants of the dissected and variegated cultivars on their own roots almost always fail to grow into good plants (Gelderen & Oterdoom, 1994). Due to low bud-forming capacity, propagation by grafting and cuttings are difficult to perform, so the micropropagation technique is widely used now took an impressive turn, being used on large scale at international level to obtain propagation material.

In vivo rooting capacity of 'Kanzan' cherry micr oshoots was studied according to nutrient substrate, microshoots height and rooting stimulant. From the interaction of the three factors (A×B×C), the 18 experimental variants have revealed that the best in vivo rooting capacity (84%) was w hen 2.5 to 4.5 cm height microshoots were planted in peat mixed wi th perlite (1:1) and treated with Radistim.

Lemoine', 'Charles Joly' and 'Sensation' cultivars. The results obtained allow the recommendation of in vivo rooting simoultaneously with the acclimatization, shortening the rooting time of microcuttings and production cost, which will lead to an improvement of the in vitro micropropagation biotechnology of lilac.

The bulbs were purchased from a certified facility for production and marketing of propagating material, to assure the authenticity of species and varieties. For each species and variety were planted 10 bulbs, following the bulbous planting technological sequences: depth 10 cm, distance between bulbs/row – 10 cm, distance between rows – 25 cm and numeric labeling. To eliminate the risk of bulbs' damage, they are removed from the soil every year, are sorted, treated and stored properly.
