Metabolic changes during the development and maturation of Triticum durum Desf. (L.) kernels were studied, with particular emphasis on changes in the redox state of ascorbate and glutathione, as well as in the activities of the enzymes responsible for the recycling of their oxidized forms (ascorbic free radical reductase, EC 1.6.5.4; dehydroascorbate reductase, EC 1.8.5.1; glutathione reductase...

Background and objectives Durum wheat (Triticum durum Desf.), such as other cereals, contains several interesting bioactive compounds mostly found within the coating structure of kernel; also, these structures included in bran fractions, contain highest concentration both minerals organic contaminants (mycotoxins). The purpose this project was to employ micronization air-classification technolo...

Parental lines, namely: F1, F2, BC1, BC2, BC11, BC12, BC21, BC22, BC1 selfed, and BC2 selfed generations of three crosses involving six cultivars of durum wheat (Triticum durum Desf.) were studied for awn length under normaland late-sown environments to analyze the nature of gene effects and components of heterosis (over the better parent). A sixparameter model in the cross Cocorit 71 x A-9-30-...

Breeding for solid-stemmed durum (Triticum turgidum L. var durum) and common wheat (Triticum aestivum L.) cultivars is one strategy to minimize yield losses caused by the wheat stem sawfly (Cephus cinctus Norton). Major stem-solidness QTL have been localized to the long arm of chromosome 3B in both wheat species, but it is unclear if these QTL span a common genetic interval. In this study, we h...

Plants exploit ubiquitination to modulate the proteome with the final aim to ensure environmental adaptation and developmental plasticity. Ubiquitination targets are specifically driven to degradation through the action of E3 ubiquitin ligases. Genetic analyses have indicated wide functions of ubiquitination in plant life; nevertheless, despite the large number of predicted E3s, only a few of t...

The diffusion of no-tillage (NT) is to be encouraged because the benefits it can provide in terms improving soil fertility and counteracting global warming climate change as part climate-smart agriculture practices. However, introduction this management difficult, especially first years application, lead unpredictable yield results depending on type. Therefore, aim experiment was evaluate early...

Restriction map variation in two 5-6-kb chloroplast DNA regions of five diploid Aegilops species in the section Sitopsis and two wild tetraploid wheats, Triticum dicoccoides and Triticum araraticum, was investigated with a battery of four-cutter restriction enzymes. A single accession each of Triticum durum, Triticum timopheevi and Triticum aestivum was included as a reference. More than 250 re...

To investigate the effects of salinity stress on durum wheat cultivars at critical stages germination and seedling establishment under stress, a study was conducted eight (Karim, Khiar, Inrat100, Maali, Monastir, Portodur, Razeg, Salim) subjected to an increasing concentration by using sodium chloride (NaC) (0, 2, 4, 6, 10 g L−1). Germination physiological parameters were measured thoroughly an...

The present study was aimed to investigate, the chemical composition of essential oil extracted by hydrodistillation from Fennel (Foeniculum vulgare Mill.) harvested in South-Est, Algeria, and evaluate its antifungal allelopathic activities. Gas chromatography-mass spectrometry GC-MS analysis F. showed presence 11 components, alpha.-phellandrene (29.44%) found as main component. tested on seeds...
