title: Shoot and root organogenesis of Camellia sasanqua.
abstract: In vitro-derived shoot tips, (10 mm) taken from primary cultures of Camellia sasanqua L., were evaluated for organogenesis when cultured on a half-strength MS medium supplemented with various concentrations of NAA, IBA, BA and GA3. Maximum shoot proliferation and growth for juvenile and mature tissue was obtained when 0.54 μM NAA, 8.8 μM BA plus 14.4 to 28.9 μM GA3 was added to the culture media, with a pH between 4.5 and 5.0. In vitro-derived shoots (20 mm) from mature C. sasanqua 'Day Dream' and juvenile C. sasanqua cultures initiated roots in vitro after immersion in 2.5 mM IBA for 30 min. Sixty percent of the mature shoots and 90% of the juvenile shoots initiated roots within 3 weeks of treatment with IBA.
