Table 2

Effect of ABA on calli fresh weight increase and percentage of somatic embryos regenerated from calli during indirect somatic embryogenesis of C. tenuissima Ritt. forma monstruosa.

Medium	ABA (μM)	Calli fresh weight increase (g)	Calli with somatic embryos (%)
MS ABA0^1	0	8.36 a*	66.7
MS ABA0.1	0.1	8.75 a	83.3
MS ABA1	1	7.29 a	66.7
MS ABA10	10	4.02 a	83.3
MS ABA100	100	0.50 b	66.7

 ¹Except ABA, all media contained constant concentration of the following PGRs: 13.32 μM BA; 16.11 μM NAA; 0.57 μM IAA.
