Effects of repeated elicitation with DP7 at 6 mg/L on growth and diosgenin accumulation of D. zingiberensis cell cultures.

Addition time	Dry weight	Diosgenin content	Diosgenin yield
(day)	(g dw/L)	(mg/g dw)	(g/L)
Control (without elicitation)	3.070 ± 0.217 c	0.126 ± 0.012 d	0.387 ± 0.061 d
Days 24 and 26	3.809 ± 0.164 a	0.931 ± 0.039 a	3.548 ± 0.280 a
Day 26	3.898 ± 0.143 a	0.821 ± 0.029 b	3.203 ± 0.222 b
Days 26 and 28	3.332 ± 0.057 b	0.733 ± 0.021 c	2.440 ± 0.030 c

Note: The values represent means ± standard deviations (n = 3). Different letters indicate significant differences among the treatments in each column at p = 0.05 level.
