Drought is one of the major threats to cowpea productivity in tropical countries, and understanding its impacts germane ensuring food security a global context. The present study was established screen some accessions for drought tolerance at flowering stage pots under controlled conditions house. High significant differences were observed among wilting recovery traits, stomatal conductance, re...

Dipteryx alata Vogel (Fabaceae) is a fruit tree species native to the Cerrado with ecological and economic potential. However, water deficit can be limiting factor initial growth of this species, requiring knowledge on technologies that alleviate stressful effect. We hypothesized inoculation arbuscular mycorrhizae fungi contributes stress mitigation during after deficit. D. seedlings were subje...

in order to study the effects of biofertilizers and different water volume per irrigation on vegetative characteristics and seed yield of sesame (sesamum indicum l.), an experiment was conducted at the research greenhouse of faculty of agriculture, ferdowsi university of mashhad, during 2009. this experiment was conducted as factorial based on randomized complete block design with three replica...

water salinity and drought are the major abiotic stresses limiting turf grass growth. on the other hand, shortage of waterresources and salinity of water and soil in the arid and semi-arid zones such as iran, are the restricting factors in developinglawn turf grasses. an experiment was conducted to evaluate the combined effects of water salinity and deficit irrigation ontall fescue (festuca aru...

Direct seeded rice (DSR) production has been recognised as a more efficient way for conserving both labour and water. However, in regards to irrigation brown manuring (BM), DSR gotten relatively little attention. Hence, field study was conducted findout the effect of on physiological characters yield (TRY 3) under sodic soil condition. The experiment laid out split plot design each replicated t...

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...

in order to evaluate the effect of different levels of drought stress on some physiological parameters in grapevine, a potted experiment with iranian grapevine cultivars ‘sahani’, ‘bidane-sefid’ and ‘farkhii’ was conducted in summer of 2008. the experiment was performed while employing four drought stress (water potential of soil, ?s= -0.2, -0.6, -1, -1.5 mpa) treatments each in three replicati...

Salinity is one of the most important abiotic stresses that limit crop growth and productivity. This study focuses on the effects of different strains of plant growth promoting rhizobacteria (PGPR) on the physiological responses of two wheat cultivars under normal and salt stress conditions. The wheat cultivars selected include one which is tolerant to salinity (Kavir) and one which is sensitiv...
