AN APPLICATION OF THE ACCLIMATIZATION UNIT FOR GROWTH OF CARNATION EXPLANTS, AND FOR ROOTING AND ACCLIMATIZATION OF THE PLANTLETS

M. Hayashi, M. Nakayama, T. Kozai
Explants, single node cuttings each with two leaves, of a carnation (Dianthus caryophyllus L.) excised from the plantlets in vitro were inserted in rockwool plugs and were transferred directly to the acclimatization unit (Kozai et al., 1987) and were cultured with a (sugar free) diluted nutrient solution for hydroponics.

The growth of the plantlets with this method were compared with the growth of the plantlets with the conventional method. The conventional method means here that the explants are cultured in vitro and grown to the plantlets on the medium with sugar, then acclimatized ex vitro with the (sugar free) diluted nutrient solution.

The plantlets grew faster and were more vigorous with the acclimatization unit method than with the conventional method.
