Floristic composition of the halophilic and salt-resistant plant population in Hammam-Boughrara (Oran-Algeria)

This phyto-ecological study is on halophilic and salt-resistant vegetation of Oran region. The semiarid and sometimes arid climate has been defined and confirmed from a bioclimatic point of view. The pedological approach used shows a soil with sandy to silty-sandy texture, favoring regression of the vegetation and a halophilic vegetation set up. In this study, we analyze the floristic composition of the northern region of Hammam Boughrara using multiple floristic surveys conducted at three stations along the Tafna wadi. Dominated by Mediterranean and Saharo-Sindian elements, the relatively poor flora (88 species in total) is biologically characterized by a clear dominance of therophytes (>33%) and chamaephytes (>19%) to the detriment of phanerophytes.

Germination Behaviour of a Perennial Amaranthaceae of North Western Algeria(Oran):Arthrocnemum glaucum(Del.)*** Submitted to Thermal Factor and Salt Stress

In light of the importance of seeds germinative phase in the progress of later stages of development of any particular plant species in semi-arid and arid area, it is essential to study the germinative behavior and to evaluate the tolerance of a perennial halophyte of Amaranthacaea family, Arthrocnemum glaucum (Del.) Ung. during this crucial phase. A study is devoted to this species seeds germination, which although it’s a mandatory halophyte, it’s less tolerant to salt stress in germination’ phase. Germinative tests are carried out in laboratory, on seeds putted in Petri dishes placed at different temperatures. They enable us to determine the optimal germination temperature, which is 40°C while the cold one (5°C) completely inhibits it. The seeds of Arthrocnemum glaucum show an optimum germination of 44% in distilled water (NaCl 0 mm) similar to glycophytes but they differ in their ability to germinate at higher salinities. Beyond 300 mM germination is completely inhibited. Prior to break dormancy seeds, a cold treatment at 5°C has been achieved;the germination capacity of the seeds increases with the duration of the cold treatment. It increases from 30% after 2 weeks of treatment to 80% after a treatment of 27 weeks.
