The present research work involves shoot formation, their multiplication and rooting in carnation Dianthus caryophyllus. For shoot formation both apical and nodal meristems were used. MS medium containing BAP alone or in combination with kinetin was tested. Best shoot formation response was obtained after 6 days of inoculation from apical meristem and after 7 days of inoculation from nodal meristem on MS medium supplemented with 4.0 mg/l BAR Apical meristem showed more pronounced effect for shoot formation than nodal meristem. Well-developed shoots were shifted for their multiplication. Maximum number of multiple shoots were obtained on MS medium containing 1.0 mg/l BAR These multiple shoots increased in their number when were given subsequent incubation period. Addition of Kinetin to BAP failed to show good shoot multiplication response. Shoots after attaining the size of 5.0 cm were shifted for rooting.
