A wheat growth model that includes the direct responses of canopy photosynthesis and transpiration to elevated CO, and the response of crop growth to water stress has been developed and tested. Sensitivity analyses show that different cultivars have quite different responses to changes in ambient air temperature, ambient CO2 concentration and rainfall. Because crops reach maturity earlier under...

Lysophospholipids (LPLs) are the most abundant polar lipids in wheat endosperm and naturally complex with amylose, affecting starch physicochemical properties. We analyzed LPLs in wheat flour from 58 cultivars which differ by grain hardness using liquid chromatography mass spectrometry (LCMS). There were significant differences in LPL content between cultivars, demonstrating that genotype rathe...

To determine seed storage protein banding patterns in some bread wheat cultivars and the similarity of banding patterns among different cultivars, an experiment based on seed storage protein electrophoresis (albumin and globulin) was performed. Water and salt soluble proteins were extracted in sixteen wheat cultivars using polyacrylamide gel electrophoresis and banding pattern was obtained. Stu...

The effect of different concentrations of hexavalent Cr on growth and biochemical parameters of two T. aestivum cultivars (Punjab-11 and Sehar-06) was investigated. No significant inhibition of seed germination was observed in both the cultivars at all the tested concentrations (P ˃ 0.05). A significant decrease in root length for both the cultivars was observed at all the Cr concentrations as ...

Efficient use of space and high yields are critical for long-term food production aboard the International Space Station. The selection of a full dwarf wheat (less than 30 cm tall) with high photosynthetic and yield potential is a necessary prerequisite for growing wheat in the controlled, volume-limited environments available aboard long-term spaceflight missions. This study evaluated the phot...

New crop cultivars will be required for a changing climate characterised by increased summer drought and heat stress in Europe. However, the uncertainty in climate predictions poses a challenge to crop scientists and breeders who have limited time and resources and must select the most appropriate traits for improvement. Modelling is a powerful tool to quantify future threats to crops and hence...

A knowledge model with temporal and spatial characteristics for the quantitative design of a cultural pattern in wheat production, using systems analysis and dynamic modeling techniques, was developed for wheat management, as a decision-making tool in digital farming. The fundamental relationships and algorithms of wheat growth indices and management criteria to cultivars, ecological environmen...

Wheat is the world’s largest volume crop traded internationally. Foliar diseases are the main biotic restriction reducing yield in wheat crops. Wheat productivity can be enhanced through controlling foliar disease through the use of resistant cultivars. Plant breeders are providing considerable attention to wheat genetic improvement from the past few years to minimize losses due to pests and pa...

The inoculation of soft wheat by Septoria tritici induces a foliar necrosis and an important modifications in the oxidative metabolism of which the time course clearly distinguishes the studied cultivars according to their behaviour to this disease. In the resistant cultivars (Mahdia, Achtar), the inoculation was accompanied by an early and localized necrosis and a fast and intense increase of ...

introduction integrated weed management is based on combination of several management methods, while reducing the rate of the use of herbicides, will result in efficient management and sustainable weed control. ability of crop tolerance and prevent weed growth are two important traits in weed competition. an appropriate and suitable cultivar, has high yield potential in the presence of weed and...
