Abstract In leaf derived callus cultures of Solanum laciniatum Ait. both phenolics and solasodine concentrations increased when medium phosphate or nitrogen concs. were reduced to one-eighth or when sucrose concentration was increased from 3 to 4–8 %. Under these conditions growth was reduced and final FW:DW fell. Growth was inhibited by sucrose depletion and nitrogen supple -mentation. On additional nitrogen the concentrations of phenolics and protein significantly increased, FW:DW was reduced and solasodine concentration was unaffected. In seedling derived cultures phosphate depletion resulted in a significant increase in phenolics concentration, an inhibition of growth and a rise in solasodine concentration.
