What is Somatic embryogenesis and plant recovery from mature tissues of olive cultivars (Olea europaea L.) ?canino? and ?moraiolo? about?

A cyclic system of somatic embryogenesis from mature tissues of olive (Olea europaea L.) and subsequent plant recovery were developed. The primary embryos originated from morphogenetic masses derived from petioles of shoots regenerated from tissues of two micropropagated cultivars: Canino and Moraiolo. The rejuvenation acquired by the shoots by regeneration, directly from petiole tissues or indirectly from petiole callus, seems to be essential for the subsequent somatic embryogenesis induction. Cyclic embryogenesis, both from normal embryos or teratoma, was obtained on modified olive medium (OMe) plus 0.5 μM; 6dimethylaminopurine, 0.44 μM 6-benzylaminopurine, 0.25 μM 3-indolebutyric acid and 0.42 mM cefotaxime. The production of normal embryos was higher, faster and often more clustered on a filter paper liquid medium or on a media solidified with phytagel than with agar. The capacity to produce continuous cycles of successive embryos has been maintained for over two years only in the dark, since the light inhibited embryo induction. The embryogenetic capacity was qualitatively and quantitatively enhanced by adding 0.42 mM cefotaxime. Mature embryos germinated easily by increasing
