Induction and Analysis of the Alkaloid Mitragynine Content of a Mitragyna speciosa Suspension Culture System upon Elicitation and Precursor Feeding

Table 1

Effects of different concentrations of 2,4-D on the percentage of callus induction between leaf explants and petiole explants.

Concentration of 2,4-D (mgL^−1)	Percentage of leaf explants that produced callus (%)	Percentage of petiole explants that produced callus (%)
0	4.167^bc	9.72^d
2	16.67^ab	36.11^b
4	20.83^a	70.83^a
6	4.167^bc	26.39^bc
8	0^c	19.44^cd
10	0^c	19.44^cd

Percentages within a column that have the same letter are not statistically significantly different according to Duncan’s multiple range test at 𝑃≤0.05.
