Anatomical differences between embryogenic and non-embryogenic calli of Pimpinella brachycarpa were investigated by light microscopy and electron microscopy. Initial callus tissue emerged from explants after 14 d of culturing. The embryogenic calli (EC) were firm, rather opaque, and light yellow in color. The cells usually formed small, compact clusters. Non-embryogenic calli (NEC), however, were friable, semitransparent, and yellow or gray. These formed relatively larger and loosely held clusters.
