Abstract BACKGROUND: Three annual Atriplex species— A. hortensis var. purpurea, rubra and rosea —growing on soil with various levels of the heavy metals copper, lead, nickel, zinc, have been investigated. RESULTS: Metal accumulation by plants differed among species, polluted tissues. Metals accumulated were mostly distributed in root tissues, suggesting that an exclusion strategy for metal tolerance widely exists them. The increased concentration led to increases shoot concentrations Ni, Cu,...
The effect of salt stress on the growth Atriplex hortensis was determined by growing plants in soils receiving a one-time irrigation nutrient solution containing low, medium, and high levels NaCl.Atriplex were grown sand culture under controlled greenhouse conditions.The experiment compared to two varieties A. hortensis.Growth yield progressively declined increasing NaCl concentrations.Atriplex hortensis, an annual halophyte, exhibits significant reduction height biomass saline...
Contamination by metals from anthropogenic activities has significant consequences for ecosystems and human health. Indeed, these elements, nature are non-biodegradable, have a high ecotoxicity, could be involved in many pathologies. The genus Atriplex is well adapted to extreme environmental conditions exhibits heavy metal accumulation properties. This study aimed examine the response of halophytic plant (Atriplex hortensis) soil polluted with toxic elements. To address this, we measured...
Background: Intercropping legumes with cereals for forage production is a sustainable technique showing several environmental benefits. Aim: This study aimed to investigate the effect of different levels nitrogen fertilization on yields and quality hairy vetch ( Vicia villosa , roth) –triticale (X tritcosecale witmack) mixtures. Methods: The five increasing rates (0, 10, 20 30 50 kg N ha -1 ) growth rate, yield, interspecific competition vetch-winter triticale mixture was investigated under...
SummaryInvestigations on the effects of water-deficit stress conditions physiological characteristics plants may provide a means to understand basis drought resistance. Atriplex spp. have been used as resource for rehabilitation degraded land. The responses two varieties hortensis [green orach (A. L. var. purpurea) and red rubra)] four levels soil moisture (100, 80, 60, or 40% field capacity) were investigated. experiment was conducted under greenhouse conditions. Growth declined...
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...
Background and Objective: Grass pea (Lathyrus sativus L.) is a multipurpose grain legume with an indeterminate growth habit.The objective of this study was to identify adaptation mechanisms grass water deficits.Materials Methods: In the germination experiment, used osmotic potential were: 0 (distilled water); -0.03, -0.1, -0.7 -1.0 MPa, shock induced by increasing concentrations polyethylene glycol (PEG).After treatment for 7 days, percentage, root shoot length, seedling fresh dry weight...
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...
Abstract Background Drought is a major problem limiting the growth and development of plants in world especially Tunisia. Halophytes constitute renewable wealth they offer great flexibility with regard to abiotic stresses, are evaluated for their ecological potential food use. Results The proposed work identifies response Atriplex hortensis var. rubra germinal stage reproductive under deficient water regime measure drought resistance this plant that has very interesting forage production...
Highlights Defoliation initiates physiological recovery and chemical defense mechanisms in Phalaris aquatica . Under infrequent defoliation treatment, P. has high DM production. severity on herbage regrowth was associated with variation of secondary metabolite content antioxidant activity. may be suited to conservation pasture systems; the interval between cuts is about six weeks maximize rates regrowth. Results indicate that used as fodder crop sustained production food security. Abstract....
