Regenerating of whole plants of Calendula otticicnslis, L. was achieved through direct organogenesis using leaf and cotyledonary nodes as explants. Leaves were taken from 3·week-old in vitro plantlets and cultured on MS basal medium supplemented with 200 mg/L glutamine and 500 mgl L casein hydrolisate. The medium contained SA with different auxins (2,4-0 and NAA) Prolific direct adventitious shoot regeneration occurred on most of the tested media which that contained either 2.4-0 or NAA. The best response in terms of frequency of shoot regeneration (86.64%), number of shoots per explant (7.60) and bud forming capacity (6.58) were obtained with 1.0 mg/L 2,4-0 alone. Cotyledonary node explants were cultured on MS medium,supplemented with various concentrations of Kin and NAA. The highest frequency of regenerated shoots was achieved on MS medium supplemented with 2.0 mg/L Kin and 1.0mg/L NAA (9.20). Regenerated shoots were excised and rooted, the highest number of root/shoot was obtained with half strength MS salt medium supplemented with 1.0 mg/L ISA In vitro rooted plantlets were finally transferred to mixture of peatmoss and vermiculite al equal volume w·th survival rate95% after 21 days.
