Environmental pollution is one of the most critical issues concerning quality environment and threatens human safety due to bioaccumulation. The extensive application pesticides causes great public concern about negative impacts on health. Herbicides have been used for weed management prevent yield loss agricultural products. In recent years, environment's extensively considered enormous pesticide in agroecosystems. There are some different pathways degradation herbicides environment,...
In this work, the involvement of heat shock proteins (HSP70) in barley (Hordeum vulgare) has been studied response to drought and salinity. Thus, 3 genotypes usually cultivated and/or selected Italy, Middle East/North Africa landraces 1 improved genotype from ICARDA have identify those varieties showing best stress response. Preliminarily, a bioinformatic characterization HSP70s protein family made by using annotated Arabidopsis sequences. This study identified 20 putative orthologs genome....
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...
Abstract Abiotic stresses such as drought and heat constitute one of the major constraints to global crop production, climate change will worsen scenario. There is growing interest in investigating application biostimulants palliate yield losses due impact stress. This study focuses on assessing coating seeds with either thyme essential oil or Paraburkholderia phytofirmans PsJN strain agronomic performance durum wheat subjected contrasting levels irrigation. For this aim, Tunisian genotype...
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...
This study aims to investigate the activities and expression of enzymes primary metabolism relate these data with growth performance three different durum wheat genotypes (Maali; YT13; ON66) under osmotic stress. Growth traits—including plant height, dry weight (DW) relative water content (RWC)—were measured classify depending on their tolerance Several were investigated: Ascorbate peroxidase (APX), Glutamine Synthetase (GS), dehydrogenase (GDH), Glutamate synthase (GOGAT), Glucose...
The interaction between salinity and nitrogen metabolism has been investigated in two barley landraces, one tolerant (“100/1B”) susceptible to (“Barley medenine”) from the Middle East North Africa (MENA) region. Barley plants were exposed 50 mM NaCl for 7 days; then, was increased 150 presence (10 mM) or limitation (1 of ammonium as a source. Upon salinity, “100/1B” shown support N assimilation by enhancing glutamine synthetase (GS) oxoglutarate aminotransferase (GOGAT) cycle under high N,...
Freshwater scarcity and other abiotic factors, such as climate soil salinity in the Near East North Africa (NENA) region, are affecting crop production. Therefore, farmers looking for salt-tolerant crops that can successfully be grown these harsh environments using poor-quality groundwater. Barley is main staple food most of countries this including Tunisia. In study, AquaCrop model with a module was used to evaluate performance two barley varieties contrasted their resistance three...
Abstract The use of efficient selection traits for screening under contrasting irrigation water salinity is a challenge breeders. To identify patterns, grain yield ( GY ) and components (kernels m −2 , thousand kernels weight), growth (plant height, biomass), flag leaf ion accumulation (Na + K ), carbon isotope composition δ 13 C nitrogen concentration (N grains were assessed on 25 durum wheat genotypes (G) in two consecutive growing seasons (2010 2011), three semi‐arid locations Tunisia....
The effects of nitrate were studied in wheat varieties grown hydroponic culture: two landraces (Azizi and Bidi), improved genotypes (Om Rabiaa Khiar) from Tunisia. Nitrogen (N) supply generally induced an increase plant height all varieties, albeit to a different extent; interestingly, exhibited the same N Uptake Efficiency (NUpE) as other lower Utilization (NUtE); contrast, exhibit better NUtE at high N. Nitrate reductase activity (NRA) was sensibly constitutively higher roots, while NRA...

The success of programmes improving barley performance under abiotic stress must go through an understanding mechanisms developed by the plant to counteract this stress.Our study fits into framework.It aims evaluate six genotypes from MENA region, treated with two salinity levels: 1.2 and 14 dS/m.Three are salt-tolerant, three sensitive.They were grown a controlled environment in 40L PVC tubes using sand perlite as substrate.The evaluation was based on 15 morpho-physiological parameters...
