Effects of the Ratio of Calcium to Potassium in the Nutrient Medium on the Growth and Alkaloid Production of Atropa belladonna

The increase of calcium/potassium ratios in nutrient solutions reduces growth of belladonna plants. This is evident in the reduced elongation of all stems, particularly the sympodial flowering branches, and in the fresh and dry weights of all plant parts. There appears to be a concurrent increase in...

Description
Summary:The increase of calcium/potassium ratios in nutrient solutions reduces growth of belladonna plants. This is evident in the reduced elongation of all stems, particularly the sympodial flowering branches, and in the fresh and dry weights of all plant parts. There appears to be a concurrent increase in the proportion of leaf to total plant at the expense of stem and root. The increase in calcium/potassium ratio results in higher yields of total nitrogen and alkaloids.
