The aims of our experiment were to evaluate the uptake and translocation of cerium and titanium oxide nanoparticles and to verify their effects on the growth cycle of barley (Hordeum vulgare L.). Barley plants were grown to physiological maturity in soil enriched with either 0, 500 or 1000 mg · kg(-1) cerium oxide nanoparticles (nCeO₂) or titanium oxide nanoparticles (nTiO₂) and their combinati...

drought stress is one of the important problems in arid and semi_arid regions. drought stress take place in plants when available water is lesser than evapotranspiration. in order to evaluate the effect of drought stress on morphological traits and yield of three medicinal plants an experiment was carried out during the 2010 year in research greenhouse of faculity of agriculture, ferdowsi unive...

BACKGROUND AND AIMS Genotypic variation in tillering can be caused by differences in the carbon supply-demand balance within a plant. The aim of this study was to understand and quantify the effects of genotype on tillering as a consequence of the underlying internal competition for carbohydrates. METHODS Five sorghum hybrids, derived from inbred lines with a common genetic background and wit...

Grain yield in wheat (Triticum aestivum L. emend. Thell.) is highly dependent upon the number of spike-hearing tillers produced by each plant. Soil salinity can greatly decrease their number and productivity. Knowing the contribution of specific tillers is essential for breeding salt-tolerant genotypes and for developing wheat growth simulation models. Our objective was to determine the effects...

A field experiment was conducted during kharif season of 2010 and 2011 to investigate the optimization of nitrogen levels under different age of seedlings transplanted on growth, chlorophyll content, yield and economics of hybrid rice. Fifteen treatment combinations consisted of three levels of seedlings age (10, 20 and 30 days) and five levels of nitrogen viz. N0, N50, N100, N150 and N200 kg h...

Mortality of tillers in barley (Hordeum vulgare L.) is an important developmental event affecting spike number and yield potential of the crop. It has traditionally been thought that increased shading of young tillers by the developing canopy initiates the premature senescence of tillers. A series of field experiments were conducted in 1982, 1983, and 1984 at St. Paul, MN on a Waukegan silt loa...

Wheat (Triticum aestivum L. emend. Thell.) grain yields are highly dependent upon the number of spike-bearing tillers produced per plant. Salinity, drought, and other environmental stresses can greatly affect the development and viability of tillers. We determined the effects of soil salinity on the occurrence and rate of tiller development and the incidence of tiller abortion in spring wheat c...

abstract plant- growth promoting rhizobacteria enhance plant growth and yield directly and or indirectly. a factorial experiment was conducted in greenhouse to determine the efficacy of four strains of fluorescent pseudomonas on wheat yield and yield component under saline conditions. the experiment was carried out with the following treatments (non –inoculation control and inoculation with p.f...
