Drought is one of the harshest abiotic stresses hindering seed germination, plant growth, and crop productivity. A high rate uniformity germination under stressful conditions are vital for establishment growth; thus, better understanding genetic architecture drought stress a prerequisite further increasing yield potential. Barley considered most stresses-tolerant cereals. Elucidating tolerance barley during would indeed pave way towards improving performance all However, we still know...

Drought stress can occur at any growth stage and affect crop productivity, which result in large yield losses all over the world. In this respect, understanding genetic architecture of agronomic traits under drought is essential for increasing potential harvest. Barley considered most abiotic stress-tolerant cereal, particularly with respect to drought. present study, worldwide spring barley accessions were exposed beginning from early reproductive 35% field capacity conditions. had...

Drought induces several challenges for plant development, growth, and production. These become more severe, in particular, arid semiarid countries like Egypt. In terms of production, barley ranks fourth after wheat, maize, rice. Seed germination seedling stages are critical establishment growth. the current study, 60 diverse genotypes were tested drought tolerance using two different treatments: control (0-PEG) (20%-PEG). Twenty-two traits estimated seed parameters. All reduced under stress,...

Heat stress is one of the abiotic stresses that cause a significant reduction in barley yield. Climate change will increase number heatwaves, which result more deterioration agricultural sector. Therefore, understanding physiological changes occur plant to tolerate heat very important. A collection 60 Egyptian spring genotypes has been tested for under field conditions. To quantify yield-related traits and grain-reserve parameters as indicators tolerance, several were scored. The causative...

Salt tolerance at germination and seedling growth stages was investigated. GWAS revealed nine genomic regions with pleiotropic effects on salt tolerance. tolerant genotypes were identified for future breeding program. With 20% of the irrigated land worldwide affected by it, salinity is a serious threat to plant development crop production. While wheat most stable food source worldwide, it has been classified as moderately salinity. In several plants; such barley, maize rice, shown that seed...

Abstract Background Alkaline-saline (AS) stress threats crop development and productivity. Understanding the genetic control of AS tolerance in wheat is important to produce cultivars that outstand such a severe condition. Methods A set 48 were tested under controlled conditions at seedling maturity stages. The effect on seedlings kernel traits was measured select tolerant high-yielding genotypes. Single-marker-analysis (SMA) gene enrichment conducted understand both growth Results decreased...

Titanium dioxide nanoparticle (nTiO2) is one of the most produced nanoparticles worldwide. Its mechanism on crop development and performance unclear as it hard to predict their toxicity or benefit. Therefore, understanding genetics under nTiO2 a prerequisite for applications in agriculture improvement. Here, we aimed examine influnce 300 ppm seed germination, seedling morphology, root-related traits 121 worldwide spring barley (Hordeum vulgare L.) accessions. Results show that significantley...

Wheat plants experience substantial physiological adaptation when exposed to salt stress. Identifying such mechanisms and their genetic control is especially important improve its tolerance. In this study, leaf chlorophyll content (CC), canopy temperature (CT), specific area (SLA) were scored in a set of 153 (103 having the best genotypic data used for GWAS analysis) highly diverse wheat genotypes under On average, CC SLA decreased stress, while CT average was higher stress compared control....

Frost is an abiotic stress factor that threatens plant development and crop productivity not only in cold regions but also temperate zones. Roots play important role growth during frost stress. Therefore, variation root characteristics could be studied to improve tolerance winter faba bean. The present study aimed identify the genomic control a bean population by focusing on root-related traits. A set of 185 genotypes were tested for under artificial conditions at -16°C, -18°C, -19°C...
