Mohammed A Basahi College of Science and Arts Sajir Shaqra University P.O. Box 33, Shaqra 11961 Saudi Arabia [email protected] Draft00966582223689 1 https://mc06.manuscriptcentral.com/botany-pubs Botany Page 2 of 27 Abstract The main objective of this study was to determine the effects of temperature, light/darkness, and salinity (NaCl) on seed germination of Anabasis setifera Moq. and the effects of alleviating salinity stress using distilled water. One-hundred percent of seeds completed germination at 15/5, 20/10, and 20°C, and a higher percentage of seeds completed germinationin light than in the dark at 20/10 and 25/15°C. The percentage of seeds that completed the germination decreased as salinity increased from 0 to 700 mM NaCl. Seeds that did not complete germination in the 800 or 700 mM NaCl solutions completed its germinationDraft after being transferred to distilled water, with a recovery rate of 94.5% and 75.5%, respectively, at 25/15°C. The inhibitory effect of NaCl on the completion of germination in this species probably occurs via an osmotic effect. -

The vegetation along the roads was disturbed and the erosion started immediately after the disturbance caused by the road construction. Our assumption is that biotechnical measurements should prevent the problems caused by erosion and improve stabilization of road edges. The knowledge of plant species which are able to grow in unfavourable conditions along the roads is important for correct selection of plants used for outplanting. The vegetation succession was observed using phytosociological relevés as a tool of recording and mapping assambblages of plants species along the roads as new linear structures in the landscape. Data from phytosociological relevés were analysed and the succession was characterised in different altitudes. The results can help us to select group of plants (especially shrubs and trees), which are suitable to be used as stabilizing green mantle in various site conditions and for different purposes (anti-erosional, ornamental, protection against noise or dust, etc.). -

Botanical Composition and Species Diversity of Arid and Desert Rangelands in Tataouine, Tunisia
land Article Botanical Composition and Species Diversity of Arid and Desert Rangelands in Tataouine, Tunisia Mouldi Gamoun and Mounir Louhaichi * International Center for Agricultural Research in the Dry Areas (ICARDA), 2049 Ariana, Tunisia; [email protected] * Correspondence: [email protected]; Tel.: +216-7175-2099 Abstract: Natural rangelands occupy about 5.5 million hectares of Tunisia’s landmass, and 38% of this area is in Tataouine governorate. Although efforts towards natural restoration are increasing rapidly as a result of restoration projects, the area of degraded rangelands has continued to expand and the severity of desertification has continued to intensify. Any damage caused by disturbances, such as grazing and recurrent drought, may be masked by a return of favorable rainfall conditions. In this work, conducted during March 2018, we surveyed the botanical composition and species diversity of natural rangelands in Tataouine in southern Tunisia. The flora comprised about 279 species belonging to 58 families, with 54% annuals and 46% perennials. The Asteraceae family had the greatest richness of species, followed by Poaceae, Fabaceae, Amaranthaceae, Brassicaceae, Boraginaceae, Caryophyllaceae, Lamiaceae, Apiaceae, and Cistaceae. Therophytes made the highest contribution, followed by chamaephytes and hemicryptophytes. Of all these species, 40% were palatable to highly palatable and more than 13% are used in both traditional and modern medicine. Citation: Gamoun, M.; Louhaichi, M.

Vegetation and Grazing in the St. Katherine Protectorate, South Sinai, Egypt
Rebecca Guenther: OpWall Plant Report Vegetation and Grazing in the St. Katherine Protectorate, South Sinai, Egypt Report on plant surveys done during Operation Wallacea expeditions during 2005 Rebecca Guenther ABSTRACT Plants were surveyed in the St. Katherine Protectorate of South Sinai, Egypt. The most commonly recorded plant species include: Artemisia herba-alba, Artemisia judaica, Fagonia arabica, Fagonia mollis, Schismus barbatus, Stachys aegyptiaca, Tanacetum sinaicum, Teucrium polium and Zilla spinosa. Dominant plant families were Compositae, Graminae, Labiatae, and Leguminosae. Communities with a high grazing pressure had a lower overall plant health. A strong negative correlation was found between plant health and grazing pressure. Twelve plant families showed heavy grazing pressure, including Resedaceae, Caryophyllaceae, Polygalaceae, Juncaceae, Solanaceae, Geraniaceae, Ephedraceae, Globulariaceae, Urticaceae, Moraceae, Plantaginaceae, and Salicaceae. INTRODUCTION The Sinai Peninsula has geographical importance in that it is where the continents of Africa and Asia meet. The St. Katherine Protectorate covers the mountainous region of Southern Sinai. It was declared as a protected area in 1996 due to its immense biological and cultural interest. It has been recognized by the IUCN as one of the most important regions for floral diversity in the Middle East, containing 30% of the entire flora of Egypt and a great proportion of its endemic species. Within the Protectorate, more than 400 species of higher plants have been recorded, of which 19 species are endemic, 10 are extremely endangered and 53 are endangered. Localized overgrazing, uprooting of plants for fuel or camel fodder, and over-collection of medicinal and herbal plants are greatly threatening the floral diversity of the Protectorate. -

Vol. 60, No. 1, pp. 147-168 (2020) Egyptian Journal of Botany http://ejbo.journals.ekb.eg/ Characterization of the Wild Trees and Shrubs in the Egyptian Flora Heba Bedair#, Kamal Shaltout, Dalia Ahmed, Ahmed Sharaf El-Din, Ragab El- Fahhar Botany Department, Faculty of Science, Tanta University, 31527, Tanta, Egypt. HE present study aims to study the floristic characteristics of the native trees and shrubs T(with height ≥50cm) in the Egyptian flora. The floristic characteristics include taxonomic diversity, life and sex forms, flowering activity, dispersal types,economic potential, threats and national and global floristic distributions. Nine field visits were conducted to many locations all over Egypt for collecting trees and shrubs. From each location, plant and seed specimens were collected from different habitats. In present study 228 taxa belonged to 126 genera and 45 families were recorded, including 2 endemics (Rosa arabica and Origanum syriacum subsp. sinaicum) and 5 near-endemics. They inhabit 14 habitats (8 natural and 6 anthropogenic). Phanerophytes (120 plants) are the most represented life form, followed by chamaephytes (100 plants). Bisexuals are the most represented. Sarcochores (74 taxa) are the most represented dispersal type, followed by ballochores (40 taxa). April (151 taxa) and March (149 taxa) have the maximum flowering plants. Small geographic range - narrow habitat - non abundant plants are the most represented rarity form (180 plants). Deserts are the most rich regions with trees and shrubs (127 taxa), while Sudano-Zambezian (107 taxa) and Saharo-Arabian (98 taxa) was the most. Medicinal plants (154 taxa) are the most represented good, while salinity tolerance (105 taxa) was the most represented service and over-collecting and over-cutting was the most represented threat. -
Origin and Age of Australian Chenopodiaceae

Using a previously published rbcL phylogeny of the Amaranthaceae–Chenopodiaceae alliance (Kadereit et al. 2003) and new ITS phylogenies of the Camphorosmeae and Salicornieae, we conclude that Australia has been reached in at least nine independent colonization events: four in the Chenopodioideae, two in the Salicornieae, and one each in the Camphorosmeae, Suaedeae, and Salsoleae. Where feasible, we used molecular clock estimates to date the ages of the respective lineages. The two oldest lineages both belong to the Chenopodioideae (Scleroblitum and Chenopodium sect. Orthosporum/Dysphania) and date to 42.2–26.0 and 16.1–9.9 Mya, respectively. Most lineages (Australian Camphorosmeae, the Halosarcia lineage in the Salicornieae, Sarcocornia, Chenopodium subg. Chenopodium/Rhagodia, and Atriplex) arrived in Australia during the late Miocene to Pliocene when aridification and increasing salinity changed the landscape of many parts of the continent. The Australian Camphorosmeae and Salicornieae diversified rapidly after their arrival. The molecular-clock results clearly reject the hypothesis of an autochthonous stock of Chenopodiaceae dating back to Gondwanan times. -

AL-Mounasi **Fatin A-J- Mustafa * Basrah Technical institutes, IRAQ. **Department of Biology,College of Education ,University of Basrah ,Basrah, Iraq. (Received 21 January 2009, Accepted 3 March 2009) Key words : Juncus rigidus , biological activity , protoscolices. ABSTRACT The aim of the present study was to evaluate the protoscolicidal activity of aqeous and 70 % alcoholic extracts of the seed of the plant (Semmar) Juncus rigidus with different concentrations (5,10,15,20) % . The results showed that all concentrations have the ability to kill the protoscolices at 4- 8 days after treatment . The aqeous extract of the concentration (20)% showed the ability to kill all the protoscolices at the fourth day after treatment more than any concentration according to R.L.S.D. test. The aqeuos extract in all concentrations have more effect than the alcoholic extract on killing the protoscolices at the same concentrations. Hank´s reservative solution has been proved to keep the control group alive up to (20) days. INTRODUCTION Juncus rigidus (Juncaceae), the common name is samara and assla. It is grown native in Iraq specially in Basrah. In germination and propagation testing, J. rigidus has a wide ecological tolerance.[1] (Figer-1-) . In vitro studies have shown that phototoxins from J. effusus enhanced antimicrobial activities n light and have antifungul ctivity to Candida albicans. [2] In vivo the alcoholic extract of J. acutus showed significant anti-eczematic activity. The isolation of five phenolid glycosices which responsible for this activity were isolated and identified as oxyresvaratrol 2-OB-D-glucopyranoside 1 resvertatrol 3 , 4 – 0 , 0 – di – B – D , canthosideB4, and caffic acid glucopyranoside5.
