Variability of the average specific growth rate based on frond area (r_(area)).

Basic descriptive statistics of the area-related (r(area)) average specific growth rate (day 0–7) [d−1] of Lemna gibba for each systematic negative control experiment and for all six experiments combined, based on 16 groups of six randomly selected replicates. Data show the variability of the growth rate within and between experiments and document the stability of the experimental set-up.
