Zusammenfassung:A cutting apparatus for cutting plant tissue for micropropagation has a tubular cutter (33) which is mounted in a tube (51) and is moveable downwardly to effect cutting of plant tissue against a cutting surface. The cut portion of plant is retained in the bore of the cutter (33) and transferred to a nutrient medium, where it is ejected by downward movement of a blade (11). Further downward movement of the blade (11) then tips the cut portion of plant upright to a growing position. The blade (11) is offset from the central axis of the tubular cutter (33). Legs (55 and 56) limit the depth of movement of the blade (11). A triangular cut out (57) in the tube (51) allows rotation of the cutter (33). In a modification, a tubular cutter cuts by shear rather than pressure and rotation.
