Zusammenfassung:	PCT No. PCT/GB90/01447 Sec. 371 Date Mar. 2, 1992 Sec. 102(e) Date Mar. 2, 1992 PCT Filed Sep. 19, 1990 PCT Pub. No. WO91/03929 PCT Pub. Date Apr. 4, 1991.In a method of cutting plant tissue for micropropagation, a container (42) containing plantlets (43) Is rotated on a turntable (19). A laser beam (35) is focused on a side wall (36) of the container below the level of a nutrient medium (45). The container (42) is rotated while the laser (35) cuts free an upper portion (36) of the container (12). After cutting, plant material is cut in a subsequent step by the same laser. Preferably the container is inverted during cutting of container and plantlets.
