Abstract:

 Problem statement: The Lygeum spartum L. represented by a single 
species occupies several regions of the Mediterranean basin. This plant plays 
an important ecological role in the fight against desertification and economic 
development in the manufacture of paper pulp. Approach: However, 
the cytogenetic studies in mitosis in this species revealed the existence of two 
ploidy levels: 2n = 40 among the population grows in the coastal region of Oran 
in the semi-arid climate and 2n = 16 in the high plateaus characterized by an 
arid climate. Results: The study of the anther, pollen grains 
and the meiotic division conducted on these two populations of Lygeum spartum 
L. growing in the two regions has confirmed these data in that the microscopic 
observations were used to determine the ultrastructure of the anther, the shape 
and size of pollen grains which morphometric data (L/W) showed significant difference 
between the two populations. The microsporogenesis was followed on the mother 
cells of pollen grains in order to understand the formation of tetrads, then the 
enumeration of chromosomes was carried out in diakinesis (n = 20) for the coastal 
population of Oran and metaphase I (n = 8 ) for the population of the high plateaus. 
Conclusion/Recommendations: These results were consistent with 
what has been observed in mitosis, which suggested that the Lygeum spartum L. 
may submit two cytotypes to adapt to different geographical and climatic environments.
