Researches concerning the multiplication in vivo of Lisianthus for promoting in Romanian green houses.

Current concerns of plant growers in Romania are to improve the flowers assortment with new species. Our researches focused on herbaceous ornamental plant Lisianthus russelianus Hook., (Eustoma grandiflora L.). It is a relatively new species in the range of cut and potted flowers for her beautiful colored and vase life. The new species introduced requires establishing efficient multiplication techniques. The biological material used in the experience were seeds from Sakata company (USA), represented by three cultivars: ‘Echo Lavender’, ‘Flamenco White’ and ‘Mirage Pastel Pink’. Also vegetative multiplication by cuttings was experimented on different culture substrate. Plants were grown in greenhouses of USAMV Cluj-Napoca and Botanical Garden “Alexandru Borza” Cluj-Napoca.
