In order to investigate the effects of developmental stage of embryos and plant growth regulators on mass production of Zantedeschia spp. Southern Light, immature zygotic embryos of Zantedeschia spp. Southern Light were cultured on Murashige and Skoog(1962) basal media or containing 2,4-D, NAA and BA. Globular embryos did not grow on any of the 2,4-D, NAA and BA combinations. The most suitable stage of immature zygotic embryo culture on the induction callus and multiple shoot was at early cotyledonary embryo stage, and at this stage of embryos were germinated up to 87.5%. The whitish watery callus and yellowish compact nodular callus produced on all 2,4-D, NAA and BA media. The best combination for inducing embryogenic callus was 0.5 mgL NAA and 1.0 mg/L BA. Whitish watery calli have been subcultured for more than 8 months and have retained their producing ability, Plant regeneration was only obtained by direct shoot development and yellowish compact nodular calli. Abundant plantlets were regenerated from cotyledonary stage of embryo culture on MS medium supplemented with 0.5 mg/L NAA and 1.0 mg/L BA. Supplementation of the media with 10£¥ coconut water showed as the best concentration for plant differentiation from direct developed of shoots. The number of regenerated plants from one embryo could be seperated 25-35s plantlets. All yellowish compact callus-derived plantlets were transferred to pots containing a mixture of vermiculite, perlite and sand(1:1;1 v/v) and 100% of divided plantlets were phenotypically normal.
