Summary
The present work provides a system for regeneration of clary sage, (Salvia sclarea L.) via organogenesis using plant tissue culture techniques in a multistage culturing medium containing 2,4-dichlorophenoxyacetic acid (2,4-D) (9.05–181.00 μM). A higher frequency of organogenic tissue initiation was obtained from immature zygotic embryo cotyledons (IZEC) 2–3 wk after pollination on the medium supplemented with 9.05 μM 2,4-D. The organogenic tissues were then proliferated on media containing both indole-3-acetic acid (IAA) and 6-benzylaminopurine (BA). Organogenic lines were established via selection, isolation and continuous subculture of organogenic tissues on a medium containing 22.19 μM BA and 2.85 μM IAA. Shoots were regenerated from both the proliferated tissues and IZEC, and propagated in the presence of IAA or α naphthaleneacetic acid (NAA), BA and gibberellic acid (GA3). Although roots were induced from regenerated shoots on the media containing a low concentration of IAA, IBA (0.98 μM) in combination with desiccation of regenerated shoots with a stem ∼10 mm in length promoted more and stronger root formation. After the root system was well established (20 mm in length), the regenerated plants were transferred to soil in plastic pots for further growth and production of R1 seeds in the greenhouse.
