Growth and secondary metabolite level in Populus L4 cell suspensions grown under normal culture conditions. Cell growth was estimated as the percent settled cell volume (the fraction of the suspension occupied by the cells, shown on the left axis) using nephelo flasks. CT and PG concentrations (percent dry weight, shown on the right axis) were determined by the Porter assay and HPLC, respectively. Data represents the mean ± SE of three biological replicates.
