Abstract
The callus induction from young fruits of Leucojum aestivum was performed on Murashige–Skoog nutrient medium supplemented with 4 mg/L 2,4 dichlorphenoxyacetic and 2 mg/L 6-benzylamynopurine. Further, by planting the obtained calluses on the same nutrient medium supplemented with 1.15 mg/L α-naphtylacetic acid and 2.0 mg/L 6-benzylamynopurine shoot cultures were established. The growth and galanthamine accumulation of obtained L. aestivum in vitro systems were studied. It was established that the amount of accumulated galanthamine strongly depended on the level of the differentiation. The maximum yield of biomass (17.8 g/L) and the maximum amount of accumulated galanthamine (2.5 mg/L) were achieved after day 35 of submerged cultivation of L. aestivum 80 shoot culture, performed under illumination. Data concerning the time courses of the utilization of the main nutrient components of the medium during cultivation of L. aestivum shoot culture are presented as well.
