Due to small biomass yields, batches of T. pannonicum and C. maritimum cultivated in high salinity conditions were not fractionated. Results are expressed as [w/w%] on a fresh weight basis. Different letters denote significantly different (p < 0.05) results calculated individually for each plant species and its biomass fractions.
