Acer platanoides has many ornamental varieties, easy to propagate by seeds, but mostly by grafting and cuttings. 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.
