| Abstract:
First attempts of cultivation of Lippia citriodora Kunth. in Slovenia date to the 1986 when first cuttings were propagated from the plant recieved from Italy. Experimental cultivation on smaller plots in the Medicinal and aromatic plant Graden of the Institute gave a lot of information about the yield, essential oil content and composition and technology required in conditions of central Slovenia. The results confirmed that the cultivation of lemon verbena in our conditions is possible. The essential oil content in dried leaves was season and hrvest dependent and varried from 0,81 ml/100g to 1,19 ml/100g. Considering planting date two harvests were possible. The GC analysis of essential oil comopsition showed that citral, limonene and citronellol were the major components. The plant is not winterhard and from different strategies tested only wintering under hetead plastic tunnels was sucessfull. Technology now used comprises of vegetative propagation from mother plants kept in greenhouse and planting in the field. The plant is cultivated as an annual plant til first frosts. Different planting distances were tested and the distance 40 X 40 cm proved optimal concerning the yield potential per area (11,8 kg and 119,3 ml of essential oil per 100 m2). During the years of vegetative propagation plants with four or five leaves per nodium emerged. Propagation by cuttings and in vitro methods were used to test stability of the feature. The incidence of plants with increased number of leaves per nodium was higher when cuttings were made from fourleaved plants. The stability of multiple leaves could not be achieved by in vitro propagation. | |
