Regeneration of Paeonia mlokosewitschii Lom. and P. tenuifolia L. in vitro from different explants

Abstract: The pattern of regeneration from tissues of Paeonia mlokosewitschii and P. tenuifolia cultured in vitro in the same chemical conditions depended on the initial explant. Direct shoot regeneration was obtained from the bases of petioles and petals, and leaf veins. Vegetative initial buds and regenerated in vitro shoots produced on their bases slowly growing nodular callus which was very productive in repetitive shoot regeneration. The tops of stems, flower bases, sepals, petals and ovary walls … Show more

“…[20]. В работе T. Orlikowska et al [15] была достигнута прямая регенерация P. mlokosewitschii и P. tenuifolia из вегетативных почек, жилок листа, оснований черешков и лепестков. Однако количество жизнеспособных эксплантов при этом не превысило 10%, а длительность культивирования от введения в культуру до получения полноценных растений-регенерантов составила 1.5 года.…”

“…Direct shoot induction is more prevalent in peony in vitro culture with several successful cases reported for both herbaceous peony (Hosoki et al, 1989;Gabryszewska, 1998) and tree peony (Bouza et al, 1994a, b;Kong and Zhang, 1998). Buds, shoot tips, nodal stem, petioles and leaf segments can be used for direct shoot induction; the highest frequency of shoot induction has been found in vegetative axillary buds or shoot tips (Hosoki et al, 1989;Orlikowska et al, 1998;Guo, 2001;Hu et al, 2003;Tian et al, 2010). Many methods were reported to enhance axillary shoot formation, such as the addition of thidiazuron (TDZ) at very low concentrations (0.01 to 0.04 mg l -1 ) to the medium containing a mixture of 6-benzyladenine (BA) (1, 2 and 4 mg l -1 ) + 6-γ-γ-dimethylaminopurine (2iP) (1, 2 and 4 mg l -1 ) + kinetin (Kin) (1, 2 and 4 mg l -1 ), a longi-tudinal shootsplit method in subculture (Hosoki et al, 1989;Gabryszewska, 1998) and manipulation of the light spectral quality under photoautotrophic conditions (Ding et al, 2010).…”
