Proline as a key osmoregulating solute in plants plays an overriding role in osmotic pressure adjustment of the cell under water stress conditions. In plant, a bifunctional enzyme delta-1-pyrroline-5-carboxylate synthetase (p5cs) promotes and directs proline synthesis during drought stress conditions. The activity of this enzyme is strongly induced to increase proline concentration within the c...
this study was conducted to evaluate the effect of drought stress on 22 durum wheat genotypes. different characteristics such as grain weight per spike, plant biomass, 100 grain weight, free proline content in leaves, and percentage of cell membrane damage were studied in greenhouse and laboratory conditions. genotypes were sown under normal irrigation and moisture stress conditions. in stress ...
Peanut is grown mostly in rainfed areas where drought is a recurring problem. Peanut genotypes with high transpiration efficiency (TE) use less water and produced yield better under drought conditions. Specific leaf area and SPAD chlorophyll meter reading are used as surrogate traits for TE. N2 fixation (NF) is also used as a surrogate trait for yield under drought. The objective of this study ...
Groundwater drought is a natural hazard that develops when groundwater systems are affected by climatical drought, when climatical drought occures, first groundwater recharge, later groundwater levels and groundwater discharge decrease. The origin of drought is a deficit in precipitation and that takes place in all the elements that comprise the hydrological cycle (flow in the rivers, soil mois...
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
in order to map qtls controlling phonological traits of barley under normal and drought stress conditions, an experiment was conducted by 72 doubled-haploid lines and their two parents (steptoe and morex), at the research farm, college of agriculture, university of zabol, in 2011. the experiment was arranged in completely randomized block designs with three replications under normal irrigation ...
Sesame is one of the plants that due to the high content (47-52%) and high quality (low cholesterol and some antioxidants) its seed oil, important role has in human health. An experimental with objective to evaluate eight local landraces of sesame to drought stress based on grain yield and drought tolerance indices using factorial split plot design was conducted with three replications in resea...
Today, there are many factors affecting watersheds, consequently changing natural ecosystems succession. The aim of this study was to investigate the effect of drought events on land use changes at Doiraj Watershed of Ilam Province from 1996 to 2015. For this purpose, Landsat satellite images were used for land use change monitoring and Standardized Precipitation Index (SPI) was applied for dro...
In order to investigate the effect of salicylic acid on photosynthetic pigments, enzyme activity and yield of durum wheat cultivars under drought stress, a greenhouse experiment was conducted as factorial based on complete randomized design with 3 replicates. Treatments included of drought stress in two levels of normal irrigation and drought stress at the beginning of the milking stage, and sa...
