In vitro regeneration from mature leaf explants of Pelargonium rapaceum (L.) L’Hérit
چکیده انگلیسی

Methods to regenerate whole plants from mature leaf explants of Pelargonium rapaceum (L.) L’Hérit were established. To optimize shoot induction, leaf explants were cultured on media containing different types and combinations of plant growth regulators. Growth was initiated within 17–24 days culture, and included callus formation, and root or shoot organogenesis ranging from 20 to 100% regeneration. Shoots were induced only when explants were cultivated on MS medium containing a combination of NAA and kinetin, NAA and BAP, IAA and Kinetin, or IAA and BAP. On media containing NAA and BAP, dark incubation was critical for efficient direct shoot regeneration from explants. Direct shoot formation and the highest number of shoots per explant (17.6) were obtained from leaf explants cultured in the dark for 30 days on MS medium containing 0.1 mg l−1 NAA and 0.1 mg l−1 BAP. Shoots cultured on MS medium containing 0.1 mg l−1 NAA formed tuberous roots with microtubers within 42 days. Healthy regenerated plants were acclimated and transferred to a greenhouse.

Research highlights▶ Direct shoot was observed when cultured on MS medium with NAA and BAP in the dark. ▶ Tuber roots and microtubers were developed on MS medium containing 0.1 mgl NAA. ▶ Ploidy analysis showed genetic stabilty and conformity to mother plants.
