IN VITRO PROPAGATION OF POT CARNATION FROM STEM INTERNODES

Stem internodes derived from pot cultivar 'Mini Pinky growing in a glasshouse were sterilized in NaC10 and divided into 2–3 mm segments without axillary buds. Thus prepared stem explants were placed on Murashige-Skoog medium containing macroelements reduced to one half. The effects of BA (0; 10^-7 M) and IAA (0; 10^-5 M) on regeneration capabilities of internodal segments were examined.

Both adventitious shoots and roots developed after application of BA 10^-7M and IAA 10^-5M. Sparadically, adventitious shoots were formed on BA 10^-7 M containing medium. Medium with IAA 10^-5M stimulated regeneration of roots. Callus formation was observed on all growing explants, also in control treatment without any growth regulators.
