Table 2.

Effect of lipoic acid on regeneration frequency and number of shoots from DEC tissue

DEC tissue age in months (from immature embryo isolation)	Regeneration frequency (%)		Number of shoots/callus
DEC tissue age in months (from immature embryo isolation)	No LA in SIM and SRM	LA in SIM and SRM	No LA in SIM and SRM	LA in SIM and SRM
2	92.3 ± 3.05	97.6 ± 2.5	22.0 ± 3.6^a	40.0 ± 4.5^b
4	86.0 ± 2.0*	97.0 ± 2.6*	16.0 ± 2.0^c	40.0 ± 1.5^d
6	81.0 ± 1.0**	94.3 ± 2.0**	14 .0 ± 2.0^e	33.0 ± 2.5^f

Values are the means with standard deviation (SD). Different letters in the row, in calculation of number of shoots/calli is significant (P < 0.050)

* Significant at P = 0.004

** Significant at P ≤ 0.001
