The use of meristems for the in vitro establishment of Colocasia esculenta (L.) Schott cv. ‘INIVIT MC-2012’ decreases bacterial contamination but is required to increase its growth. The objective of this work was to determine the effect of 6-Benzylaminopurine and indoleacetic acid on its in vitro establishment. Various concentrations of the two growth regulators were included in the culture medium and with the best combination the explants were cultured in shaking and static liquid culture medium. With the use of the culture medium constituted by 80% of the salts and vitamins MS, 30 g l-1 sucrose, 0.1 g l-1 myo-inositol, 0.1 mg l-1 6-BAP, 0.05 mg l-1 of AIA and culture in agitation were obtained meristems with the appropriate morphological characteristics to transfer to the multiplication phase at 28 days of culture.

The need of producing high quality planting material has required the searching of new alternatives to increase the efficiency of in vitro propagation methods and their automation, such as Temporary Immersion Systems. This work has been carried out to increase the multiplication coefficient in mass propagation of hybrid 'FHIA-21' (AAAB) in Temporary Immersion Systems. Different culture medium volumes per explant and densities of planting materials per unit were studied at the same immersion frequency. The highest multiplication coefficient rate, (14.99 and 16.02 respectively), was obtained when 40 ml culture medium volume were used at a density of 70 explants/flask. The use of Temporary Immersion System allowed increasing the multiplication coefficient in hybrid 'FHIA-21' (AAAB) and the highest quality multiplication coefficient for rooting stage and further acclimatization in field conditions.
