Release of embryogenic carrot cells with high regeneration potency from immobilized alginate beads

For the mass-production of regenerated carrot plantlets, embryogenic carrot callus immobilized in calcium alginate gel beads was cultivated in a growth medium and the regeneration frequency of cells released from alginate gel beads was compared with that in a suspension culture. Cells released in th...

description For the mass-production of regenerated carrot plantlets, embryogenic carrot callus immobilized in calcium alginate gel beads was cultivated in a growth medium and the regeneration frequency of cells released from alginate gel beads was compared with that in a suspension culture. Cells released in the immobilized culture were regenerated at a frequency which was about 1.5 times higher than that obtained in the suspension culture. When CaCl 2 was added to the growth medium at 5 mM, repeated batch culture for plantlet production continued for 245 d with no significant decrease in the productivity (1.6 × 10 5 plantlets/ l-medium/d).
