The leaf anatomy of miniature rose (Rosa chinensis minima) cv. RedSunblaze from in vitro culture through rooting under mist and transplanting to a greenhouse, was obsedved by scanning electron microscopy.
On the abaxial surface, plantlets culture in vitro and rooted under mist revealed deposits of raised epicuticular wax. In contrast, greenhouse plants had a flat abaxial surface with little raised epicuticular wax. Stomata were well defined on the abaxial leaf surface and were similar in size and shape (ellipsoid) in greenhouse grown or mist-rooted plantlets. Stomata of in vitro-culture plantlets were many different sizes and circular or ellipsoid.
When leaves were grown under mist or in the greenhouse , a transverse section revealed well-defined palisade (rod shape) and sponge (tube shape) mesophyll cells, while the palisade mesophyll of plantlets cultured in vitro was arranged loosely with sperical cells.
