Abstract Somatic embryogenesis, as a promising biotechnological tool for many conifer trees, has never been applied the Abies nebrodensis species. Although all encouraging results previously obtained by EU LIFE (European program) funded projects in over ten years, critically endangered Sicilian fir remains alarmingly close to extinction. In this study, we reported first protocol of somatic embr...

The possible involvement of Ca(2+)-mediated signaling in the induction/regulation of somatic embryogenesis from pro-embryogenic cells of sandalwood (Santalum album) has been investigated. (45)Ca(2+)-uptake studies and fura-2 fluorescence ratio photometry were used to measure changes in [Ca(2+)](cyt) of pro-embryogenic cells in response to culture conditions conducive for embryo development. San...

Chrysanthemum morifolium propagation through stem cutting produces weak plants that show delayed anthesis above 20 °C and a reduced flower diameter. Therefore, in this study chrysanthemum plantlets were produced somatic embryogenic from calli to exploit the somaclonal variation for their improvement. Various explants variety Dante yellow cultured on Linsmaier Skoog (LS) medium with various conc...
