Somatic embryogenesis and regeneration of plants in the bamboo Dendrocalamus strictus

Somatic embryogenesis leading to plant regeneration has been achieved in the bamboo, Dendrocalamus strictus, by culturing seeds (caryopses) on B₅ basal medium supplemented with 2,4-dichlorophenoxyacetic acid. Callus cultures obtained from the embryonal end of the seeds differentiated chlorophyllous embryoids. On transfer to a germination medium (B₅ liquid, sucrose, indolebutyric acid, and -naphthaleneacetic acid) 40% of the embryoids developed into plantlets. Further development of the plantlets occured on B₅ liquid medium (half strength) + sucrose (1%) + IBA (5 × 10^–7M) + NAA (10^–7M).Abbreviations 2,4-D 2,4-dichlorophenoxyacetic acid - IBA Indolebutyric acid - NAA -naphthaleneacetic acid
