SOMATIC EMBRYOGENESIS AND REGENERATION OF PLANTLET IN SAFFRON, CROCUS SATIVUS L.
Somatic embryogenesis was initiated in C. sativus L. from shoot meristems on LS medium containing BAP (2×10-5 M)+NAA (2×10-5 M). Various stages of somatic embryogenesis were observed in the same medium and the development was asynchronous. Somatic embryo development proceeded through well recognized sequences (globular to embryoids) with clearly discernible bipolar regions. Matured embryos coul...

متن کاملSomatic Embryogenesis in Saffron (Crocus sativus L.): Morphological Differentiation and the Role of the Antioxidant Enzymatic System
The ontogenic developmental stages of saffron somatic embryogenesis have been studied and characterized using light and electron microscopy. The embryogenic callus underwent internal segmented divisions with the formation of globular embryos that were attached to the callus surface by a broad multicelular structure. Further development of the embryoids was characterized by the emergence of a sh...
