GROWTH AND REGENERATION OF PALMAROSA [CYMBOPOGON-MARTINII (ROXB) WATS] CALLUS TISSUES UNDER VARIED NUTRITIONAL-STATUS

Callus could be induced from nodal explant of mature tillering plant of C. martinii in different basal media suplemented with 2,4-dichlorophenoxy acetic acid (2,4-D) and kinetin (Kin). Shoot bud was regenerated from such calli in MS and B5 basal media modified with various combinations of phytohormones, vitamins and amino acids. Root formation was induced either in white basal medium or half-strength MS or B5 media containing napthalene acetic acid (NAA) or indole-3-butyric acid (IBA). High survival percentage of regenerated plants in soil was obtained after acclimatization in normal environment.
