Detail Effect of genotype, explant size, position, and culture medium on shoot generation of Gerbera jamesonii by receptacle transverse thin cell layer culture (in Scientia Horticulturae 111 (2007) 146–151) Bibliografi Author: Duong Tan Nhut ; Nguyen, Thi Dieu Huong ; Nguyen, Trinh Don ; Nguyen, Thanh Hai ; Nguyen, Quoc Thien ; Nguyen, Hong Vu ; Truong, Thi Thuy An Topik: Gerbera jamesonii; Genotype; Receptacle; TDZ; TCL Bahasa: (EN )     Tahun Terbit: 2007     Jenis: Article - diterbitkan di jurnal ilmiah internasional Fulltext: gerbera tcl.pdf (129.75KB; 0 download) Abstract An unique procedure for the mass shoot propagation of Gerbera using receptacle transverse thin cell layer (tTCL) culture procedure was developed. Genotype, flower bud age, explant size, position of receptacle tTCLs and culture media were found to affect the success of culture. Ten interspecific crosses of Gerbera showed different shoot regeneration rates and callus induction via receptacle tTCL culture, all of which had shoot regeneration rates higher than 57%. Flower buds collected on the 10th day resulted in 91% shoot regeneration after 6 weeks of culture on basal MS medium [Murashige, T., Skoog, F., 1962. A revised medium for rapid growth and bioassay with tobacco tissue cultures. Physiol. Plant. 15, 475-497] supplemented with 0.02 mg/-1l thidiazuron (TDZ), 0.8 mg l/-1 adenine and 10% (v/v) coconut water (CW). This was significantly higher than those from flower buds on the 7th and 14th days (22% and 54%), respectively. Shoot regeneration rate was the highest (94–100%) in the middle layers of the receptacle. For mass shoot propagation, shoot clusters were subcultured on half-strength MS medium supplemented with 0.5 mg l/-1 indole-3-butyric acid (IBA), 0.5 mg l/-1 6-benzyladenine (BA) and 2.0 mg l/-1 kinetin after every 4 weeks. Plantlets formed when single shoots were cultured on half-strength MS medium containing 1 mg l/-1 IBA. All plantlets acclimatized well in the greenhouse.
