Our fine dings suggest that higher levels of Cu(mostly 0.625 mg CuSO 5Hao dmy stimulated the formation of longer orchid shoots and roots, RAFA et al. (2012) reported that th e h ghest number of branches and leaves per explant for apple and pear was obtained in a treatment with 0.06 mg dm a of copper in culture medium. At the rooting stage, the eleveted levels of copper very effective in stimulating root formation in both apple and pear shoots. The highest number of roots in apple was achieved while adding 0 0.2 mg dma of copper to culture medium. Th data suggest that the higher levels of copper enabled shoot and root formation in the explants, and it might be necessary to use higher levels of this medium component in orde to enhance the morphogenetic potential of explanta. JoeHI and KoTHARI(2007) reported that elevated concentrations of copper in medium had a positiv effect on the induction of shoat buds and their further development from cotyledon explants of Capsicum annuum L. The highest number of shoots nd longer shoots were obtained from 1 explant on medium with 4.8 mg Cu80,dm
