Figure 5.

Dry weight biomass accumulation in cultures of four investigated R. graeca root lines after 28, 35, and 42 days of culturing with and without immobilization on PUF rafts. Presented data are the means ± SD of three independent replicates. Grids (#) indicate statistically significant differences (p ≤ 0.05) between treatments for respective time points within root line. Asterisks (*) above square brackets point to statistically significant differences between consecutive time points within the treatment and root line (p ≤ 0.05); “con”—control cultures of respective root lines without immobilization, “PUF”—cultures of respective root lines immobilized on PUF rafts.
