Liquid culture medium optimization for P. tenuiflora suspension-cultured cells. Dry weight of the harvested P. tenuiflora suspension-cultured cells at different concentrations of sucrose (A) and 2,4-dichlorophenoxyacetic acid (2,4-D) (B), different pH (C), and medium types containing different nitrogen nutrients (D). The values represent the mean ± standard errors (n = 3).
