seed and oil yields, its components and two physiological indices including leaf canopy temperature (tc) and relative water content (rwc) were evaluated in two spring oilseed rape cultivars (rgs 300 and hyola 401) under non-stressed and water deficit imposed during stem elongation, flowering and seed filing stages. the experiments were conducted as a factorial consisted of 2 factors including i...

Tunisia is known to be a country with poor water resources, and scarcity evident in certain regions. In the long term, this situation could worsen, given increased risk of drought. The olive tree (Olea europaea L.) one plants best adapted climate, numerous studies have been carried out assess effects stress. aim work was study compare ecophysiological behavior main Tunisian cultivar (Chetoui) f...

Drought stress is a major environmental factor limiting plant growth. Selection of drought-tolerant plants critical importance in vegetation restoration and forestation programs. Alnus subcordata Acer velutinum are two valuable, dominant, endemic species the Hyrcanian forests. There fast-growing significant diffuse-porous hardwood afforestation reforestation. One-year old seedlings both were ex...

This study investigated the effects of cerium (Ce) on growth and fruit quality strawberries under salt stress. The findings revealed that stress markedly enhanced activities antioxidant enzymes increased contents malonaldehyde (MDA) hydrogen peroxide (H2O2) in leaves anthocyanins, phenolic compounds, vitamin C (Vc), soluble sugar (SS) titratable acid (TA) fruits. Ce improved ascorbate peroxidas...

Drought is one of the main abiotic stress factor that limits plant growth and development. effects on Borago officinalis L. (borage) plants in terms physiological antioxidant responses have been evaluated this study. In parallel with purpose, relative rate (RGR), leaf water content (RWC), osmotic potential, chlorophyll fluorescence (Fv/Fm), lipid peroxidation, hydrogen peroxide (H2O2) level, su...

Background: How plants respond to stress conditions can play an important role in the establishment and increasing crop yield. The results of researchers’ reports indicate that extensive morphophysiological biochemical changes occur under drought conditions. This study aimed investigate effects ascorbic acid (AA) calcium carbonate (CC) on guar different soil moisture Methods: experimental treat...

Drought is one of the most common abiotic stresses, affecting the growth and productivity of crop plants globally, particularly in arid and semi-arid regions. Different strategies are used to mitigate the impact of drought among crop plants. Exogenous application of different substances are known to decrease the effects of various abiotic stresses, including drought stress. The aim of this stud...

It has been suggested that certain organic aerosol components of wood smoke have enhanced ultraviolet absorption at 370 nm relative to 880 nm in two-wavelength aethalometer black carbon (BC) measurements. This enhanced absorption could serve as an indicator of wood combustion particles (“Delta-C” = UVBC370nm – BC880nm). From August 2009 to October 2010, week-long mobile monitoring campaigns wer...

OBJECTIVE To determine the frequency and nature of injuries sustained during the IRB 2011 Rugby World Cup. DESIGN A prospective, whole population survey. POPULATION 615 international rugby players representing 20 teams competing at the IRB 2011 Rugby World Cup in New Zealand. METHOD The study was implemented according to the international consensus statement for epidemiological studies in...
