Somatic Embryogenesis and Plant Regeneration from Inflorescence Culture of Java Citronella: (Cymbopogon winterianus)

Embryogenic callus was induced from immature inflorescence segmentsof Java citronella (Cymbopogon winterianus) and maintained for2 years on Murashige and Skoog's medium supplemented with 2,4-D(l mg l^–1). The callus cells retained the original chromosomenumber of 2n = 20. The somatic embryos germinated into plantletson MS basal medium or medium with IAA, NAA, BAP or KN individually(l mg l^–1). The regenerated plantlets developed a goodroot system on full strength solid MS inorganics medium withIAA (1 mg l^–1). The regenerated plants were similar tothe donor plant in morphology and had the same chromosome number,but showed some variation in the essential oil content.
