Heliotropium curassavicum L. is a sand binder salt marsh herb with enormous traditional value and widely found in South Asia America and Europe. In the direct method of regeneration from stem explants, we observed the maximum number of shoot regeneration after four weeks culture of MS elongation medium with 2.0 mg/L of 2, 4-D (17.27±0.51). It was clear that MS medium with 2.0 mg/ml 2, 4-D alone suitable for shoot multiplication as well as shoot elongation then compared to other combination of auxin and cytokinin. In vitro shoots were excised from shoot clumps and transferred to rooting medium containing 2, 4-dichlorophenoxy acetic acid (0.5-3.0 mg/L).
The maximum number of root regeneration (6.4±0.416) and root length (6.08±0.07) were observed in MS rooting medium fortified with 2.5 mg/L of 2, 4-D after 2 weeks of culture. 85% of invitro raised plantlets with well-developed shoots and roots were transferred to exvivo conditions into polythene bag containing sterile compost with ratio (v/v/v) of organic fertilizer: sand: peat (1:2:2; 3:1:0 or 2:2:1). Sixty five percent of acclimated plants were transferred to the pots under full sun where they grew well without any detectable phenotypic variations. Invitro raised plantlet methanolic extract showed better DPPH radical scavenging activity of about 89% at 10ppm. The growing interest in the substitution of antioxidants with natural ones has fostered research on plant sources and screening of raw materials to identify new antioxidants.
