A taxonomic study was recently carried out on species of the tribe Ceramieae (Ceramiaceae, Rhodophyta), following an evaluation of previously published records and on the basis of field and laboratory investigations. In Morocco, the tribe is represented by 5 genera: Ceramium (21 taxa at specific and infraspecific levels), Gayliella (3 species), and by one species each of Centroceras, Corallophila and Microcladia. Among these, there are five new records for Morocco: Centroceras gasparrinii, Ceramium botryocarpum, Ceramium cingulatum, Ceramium echionotum var. mediterraneum, and Gayliella taylorii. The report of C. echionotum var. mediterraneum from the Atlantic coast of Morocco is one of the rare records from outside the Mediterranean. Ceramium ciliatum var. robustum and Ceramium codii are recorded for the first time from the Atlantic coast of Morocco. Centroceras clavulatum is excluded from Moroccan flora having been misidentified for C. gasparrinii. This paper summarizes the taxonomic characters of these species with images and presents a key for their identification. This report is the first detailed record of the species of the tribe Ceramieae for Morocco. As a result, the total number of taxa at both specific and infraspecific levels accepted in the tribe Ceramieae for Morocco, under current taxonomy and nomenclature, is 27.

Secondary somatic embryogenesis in Cork oak: influence of plant growth regulators
Ben Ali Naouar,Benkaddour Rajae,Rahmouni Safaâ,Boussaoudi Ibtissam,Hamdoun Ouafaa,Hassoun Mustapha,Azaroual Latifa,Badoc Alain,Martin Patrick,Lamarti Ahmed 한국산림과학회 2023 Forest Science And Technology Vol.19 No.1
Cork oak (Quercus suber L.) is one of the most important Mediterranean forest tree species, and the Ma^amora forest-Morocco is considered to be the world largest cork oak stand. Clonal propagation of Quercus suber via somatic embryogenesis is an alternative to conventional tree propagation methods. However, complete maturation of somatic embryos is considered the major bottleneck for mass propagation of Quercus suber during somatic embryogenesis. This study focuses on influences of cytokinins on secondary somatic embryogenesis. Cytokinins showed a negative effect on the induction of secondary somatic embryogenesis. For the various concentrations tested, the number of secondary somatic embryos was significantly reduced except in the case with low dose of 2iP, which showed a slight increase. Abscisic acid (ABA) may be beneficial at low concentrations between 0.3 and 0.5mg/l. The best number of secondary embryos was given at 0.5mg/l ABA with an average number of 5 embryos from each primary embryo, which represents a slight increase below 10% compared to control medium. Also, we found that the number of responsive embryos presenting secondary somatic embryos based on their cotyledons decreased once adding ABA. Phenylurea derivatives TDZ and DPU do not promoted the process of secondary somatic embryogenesis. DPU showed no significant effect with a similar response to that of the control medium and TDZ showed an inhibitory effect. Gibberellic acid (GA3) partially blocked the process of somatic embryos multiplication, but promoted remarkably the germination of cotyledonary embryos without requesting a particular protocol. Our results provide a new insight into embryo development, establishing the basis for further research toward improvement of secondary somatic embryogenesis in Moroccan cork oak.
