Establishment of Hairy Root Cultures of Rhaponticum carthamoides (Willd.) Iljin for the Production of Biomass and Caffeic Acid Derivatives

Figure 2

Comparative growth of R. carthamoides transformed roots after 35 days in liquid medium in the light (photoperiod: 16 h of light: 40 μmol m⁻² s⁻¹) and in the dark. (a) Fresh weight (g) of harvested biomass per liter. (b) Dry weight (g) of harvested biomass per liter. The values are the mean ± SE of three successive subcultures (15–17). Means followed by the same letter at the columns (individually to fresh and dry weight) are not significantly different at the level of (the Mann-Whitney test).
