        Indirect Organogenesis through Seedling-Derived Leaf Segments of Ficus Religiosa - a Multipurpose Woody Medicinal Plant

        Mohsen Hesami,Mohammad Hosein Daneshvar 한국작물학회 2018 Journal of crop science and biotechnology Vol.21 No.2

        The aim of this study is to introduce the suitable protocol for indirect regeneration from seedling-derived leaf segment of Ficus religiosa. The leaf explant successfully produced callus on MS medium containing various concentrations of auxin in combination with BAP. The maximum callus induction (100%) was achieved in MS medium containing 0.5 mg/l 2,4-D plus 0.05 mg/l BAP and MS medium containing 1.5 mg/l NAA plus 0.15 mg/l BAP as well. MS medium consisting of 2,4-D produced yellow-brownish and friable callus (type I) while the yellowish and compact calli (type II) were obtained in MS medium consisting of NAA. On the other hand, MS medium supplemented with IBA formed greenish and compact calli (type Ш). The regeneration rate in type II callus was less than the type I, and there was no shoot induction observed on type Ш calli. MS medium supplemented with 1.5 mg/l BAP in combination with 0.15 mg/l IBA had the highest regeneration frequency (100%) and maximum shoot numbers (5.16) as well as shoot length (2.56 cm) in type I callus. A maximum of 93.33% root induction was observed in MS medium supplemented with 2.0 mg/l IBA plus 0.1mg/l NAA. The plantlets were successfully transferred to the greenhouse. This system could be utilized for large-scale multiplication of Ficus religiosa.
