Durum wheat is an important staple food crop in Tunisia and other Mediterranean countries grown various climatic conditions. Production yield are however severely limited not only by drought events but also reduced levels of nitrogen fertilisation. A study was carried out at two locations the sub-humid area Tunisia: Mateur 2009–10 2010–11 Beja 2011–12 2012–13 under rainfed Four durum genotypes (landraces: Bidi, Azizi; improved: Om Rabia, Khiar) were evaluated for agronomic efficiency related...
Nitrogen (N) is a crucial nutrient for plant growth and development. To optimize agricultural environments, N fertilizers represent critical tool to regulate crop productivity. The improvement of nitrogen use efficiency (NUE) represents promising that may enable cereal production meet future food demand. Wheat reported contrasting behaviors in utilization showing specific abilities depending on genotype. This study selected two landraces improved genotypes from Northern Africa investigate...
Pistacia lentiscus, Rosmarinus officinalis, Erica multiflora, Calicotome villosa, and Phillyrea latifolia were considered important medicinal herbs used to treat various ailments. The present study was designed evaluate the antioxidant antimicrobial activities of ethanolic extracts (EEs). P. lentiscus R. officinalis richest species in phenolic compounds. Similarly, both showed highest values flavonoids. While EEs E. C. villosa had higher amounts tannins. These compounds evaluated by two...
The present study aims to the chemical composition of essential oils from needles three pine species: Pinus halepensis Mill., P. pinaster Aiton. and pinea L., evaluation their in vitro anti-radical antibacterial properties. GC-MS analysis showed that were characterized by abundance monoterpene hydrocarbons (61.55-86.72 %). α-pinene, β-pinene, α-terpinolene, α-fenchene, β-caryophyllene most plentiful components halepensis. Limonene, particularly abundant oils. strongest DPPH-radical...
Effects of gamma rays (0.0, 100, 200 and 300 Gy) NaCl 60 120 mM) on the amino acids composition, protein fractions electrophoretic patterns two Egyptian wheat cultivars (Sids-1 Sakha-93) were investigated. The results showed that content increased by salinity irradiation doses compared to control. Concerning, albumin + globulin percentage increasing only reached maximum increase treatment mM in cultivars. But for glutenin, highest was observed 100 Gy NaCl. changes profile found be dependent...
This study was designed to evaluate the antioxidant and antimicrobial activity of ethanolic extracts (EEs)
Septoria tritici blotch (STB) is a major disease problem of wheat worldwide. To optimize the introgression resistance genes in elite genotypes throughout traditional or molecular breeding programs, full understanding quantitative inheritance to Zymoseptoria tritici, plant height (PH), and thousand kernel weight (TKW) needed. In this study, maternal cytoplasmic effects STB were investigated using P1 (susceptible, high-yielding line) P2 (resistant, low-yielding durum lines their F1, RF1, F2,...
Background: The cork oak is the major forest element of northern Tunisia, especially in Kroumirie. It a species greatecological, economic and social value, with natural distribution limited to western Mediterranean basin. Following serious biotic abiotic problems, forests have been greatly affected their regeneration has become very difficult, even almost absent these last years marked by climatic changes. association autochthonous plant such as leguminous an original research resolve this...
The present study was conducted to assess the impact of nitrogen treatment on physiological aspects cork oak (Quercus suber L.) seedlings from acorns collected seven sources (Kroumiry and Cap-bon). Nitrogen fertilization increased significantly specific leaf area (SLA) mass (LMA) Q. L grown for 2 months at concentration 1.5 g/l, respectively. Results indicate that hydraulic conductance (KLeaf) under treatment, but no significant correlation observed between KLeaf, A gs. Stomatal (gs),...
In north Tunisia, the Quercus suber L. forests have shown a great decline indices as well non-natural regeneration. The climate changes could accentuate this unappreciated situation. study, effect of water deficit on physiological behavior seedlings was investigated. Photosynthetic responses 15 months old Cork oak grown for 30 days under 40% and 80% soil content (control) were evaluated. Results showed negative positive intercellular CO2 concentration increase both photosynthesis...
Relationships between drought, carbon and water fluxes have been rarely studied in south Mediterranean forests. The present research focused on the determination of seasonal annual Quercus suber L. forests northern Tunisia. methodology was based calculation standard precipitation index, measurements trees sap flow net photosynthesis. Estimations photosynthesis transpiration during 1965-2003 period were used crop coefficients use efficiency terms.
 
 Results indicate a wide...
Understanding the functioning of shrub species during dry periods is necessary to forecast ecosystem responses future climates, particularly in Mediterranean environments. We evaluated seasonal changes leaf gas exchange, hydraulic traits, carbon and nitrogen isotopes, non-structural carbohydrates seeders resprouting typical Aleppo pine forests across an aridity gradient Tunisia: Djebel Zaghouan (subhumid climate), Mansour (semiarid transitional El Sarj (semi-arid climate). monitored seven...
This work aimed to investigate the total phenolic, flavonoid and tannin contents, antioxidant allelopathic activities of mucilage essential oils extracted from Cytisus villosus plants collected at two different provenances (Ain Drahem Feija) Jendouba Gouvernorate. Total contents in tested macerate extracts were determined using Folin-Ciocalteu, luminum trichloride Vanillin reagent, respectively. The anti-oxidant activity studied was evaluated vitro DPPH test on aerial parts (leaf branches)...
Abstract Background As part of global climate change, variation in precipitation arid ecosystems is leading to plant adaptation water-use strategies; significant interspecific differences ecophysiological response will change the behavior. The mainaim this study was investigate responses Phillyrea latifolia species seasonal drought stress. Measurements were conducted between March and December 2018. parameters studied Leaf Water Potential (ψ leaf ), Net photosynthesis (Pn), stomatal...
