Abstract
Production of
Solanum nigrum and
S. nigrum var
. judaicum plants with a high power of alkaloid accumulation was the aim of in vitro regeneration trials followed by in vivo plant acclimatization. MS-basal medium containing BA and NAA (0.5 mg/ml each) was the best for both plants. A series of in vitro and in vivo plants were successfully produced and chemical analysis revealed contents of glycoalkaloids higher than those reported for intact field plants.
