Regeneration through somatic embryogenesis from petal-derived calli of Rosa hybrida L. cv arizona (hybrid tea)

Somatic embryogenesis in callus cultures of petal explants of rose cv arizona is reported here. The calli from petals initiated on dicamba containing medium were friable and gave rise to embryos after several subcultures while those obtained from other explants did not show embryogenesis. Abscisic a...

Zusammenfassung:	Somatic embryogenesis in callus cultures of petal explants of rose cv arizona is reported here. The calli from petals initiated on dicamba containing medium were friable and gave rise to embryos after several subcultures while those obtained from other explants did not show embryogenesis. Abscisic acid and phloroglucinol were necessary during maturation and plant development, respectively. The individual embryos grew into true-to-type plants.
