Abstract:

Four Zantedeschia cultivars, namely "Golden Calla", "Pixie", "Pink Persusion" and "Black Magic", were used for this study. By ouly changing the oncentration of zeatin in Murashinge and Skoog mineral medium, good results of micropropaga-tion of Zantedeschia can be achieved even without any other rooting Phytohormone in the medium. The basic steps and the medium are given out as follows: l) shoot multiplication by adding 1 to 3mg/L of zeatin to MS medium; 2) shoot elongation by adding 0.2 to 0.4 mg/L zeatin into MS medium; 3) rooting by adding 0.05 to 0.2mg/L zeatin to MS medium.

Key words: Micropropagation, Zantedeschia, cultivar.
