Techniques for transplanting mini color-leaved plantlets of Caladium bicolor grown in test-tube

The convenient and efficient techniques for transplanting mini color-leaved plantlets of Caladium bicolor grown in test-tube and the factors affecting its transplanting survival rate were studied. The results showed that it was unnecessary to acclimate plantlets before transplant.With main techniques for transplanting plantlets mastered and proper management, the survival rate was over 96%. The best medium for transplant was the medium mixed with turf. Water the plantlets with enough water and keep the moisture for 10-15 days in the plastic film shed. The plantlets should be kept with regular aeration, watering and control of pathogens. The optimal transplanting could be done when the plantlets were 3 -5 cm high and their roots were 0.5-3.0 cm long. Suggestions on how to quicken the commercial production of plantlets were put forward.
