Effect of explant density and volume of culture medium on the in vitro propagation of the hybrid cultivar 'FHIA-21' (AAAB) in Temporary Immersion Systems
Journal Title: Biotecnología Vegetal - Year 2007, Vol 7, Issue 1
Abstract
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.
