In vitro propagation of Glehnia littoralis from shoot-tips.

Shoot cultures of Glehnia littoralis F. Schmidt ex Miq. (Umbelliferae) were established by placing shoot tip explants on Linsmaier and Skoog medium with 1 μM NAA and 10 μM BAP. Shoots were multiplied on the basal medium supplemented with 0.3 μM NAA and 3 μM BAP and rooted on medium containing either 1 μM IBA or 3-10 μM IAA. Plantlets survived in pots without any covering. This unique characteristic of the plantlets was ascribed partly to a well-developed cuticle on the surface of the leaf and the small ratio of surface area to fresh weight of a leaf blade in comparison with those of other species whose plantlets needed coverings after potting. The regenerated plantlets were finally transferred to soil.
