Teza

Introduction The environmental status of our country mobilizes us in creating green areas with a high landscaping level, a rich assortment of ornamental woody plants, resistant to biotic and abiotic factors. The decorativeness of present species and cultivars, their implementation perspective in landscape arrangement in the scientifi c literature is described [1, 2]. The new form possess a high decorativeness level, are drought and frost resistance, has a good growth on rich and light soils. Plants do not prefers special maintenance and sustain urban conditions. Species and cultivars are ornamental  and distinguish by the lengthy period of fl owering, attractive vivid colors of fl owers and leaves. Material and methods As a biological experimental material the annual shoots of this form, lignifi ed cuttings – in March-April and semi-lignifi ed one – in July-August were prepared. The obtained cuttings with solution of 0,01% de KMnO4 and heteroauxin according the method were treated [3]. Results and discussions The heteroauxin solution had a greater impact than KMnO4 one over the process of cuttings semi-lignifi ed rhizogenesis, especially on their one nr 2 (ꞌVariegataꞌ) form we established. The stimulators impact of rhizogenesis also during growth process of rooted cuttings, especially root number (5-6 per/unit) and the number of roots and greater root length (7-8 cm) was revealed (Table). Table Heteroauxin impact on the rhizogenesis process stems cuttings at the form (cultivar) of fl owering weigela Species, form Cuttings Lignifi ed cuttings Semi-lignifi ed cuttings Rooting percentage, % control 0,01% heteroauxin (16 hours) control 0,01% heteroauxin (8 hours) Weigela 50 20 40 35 60 Weigela 1 50 25 45 40 65 Weigela 2 (ꞌVariegataꞌ) 50 30 50 45 65 Conclusions As a result of multiplication by lignifi ed and semi-lignifi ed cuttings, genetically and uniformly material, so vigorous plantlets which possess the properties and qualities of the mother plants was obtained. The process of rooting cuttings depends on many factors: quality of cuttings and of the substrate, the conditions for maternal plants growth and development, the shoots until the cuttings (graftage), respecting the optimal terms of cuttings and of technology during cuttings, the density of cuttings in the in seedbeds etc. A very important role plays correctly sampling of cuttings and strictly respecting of the technology. Heteroauxin is the optimal variant for semi-lignifi ed cuttings at 1 and 2 forms was established.
