a laboratory trial was conducted to determine whether suspensions of zno nanoparticles (zno nps) could interfere with the early growth of fenugreek. this plant species is one of the recommended species by organization for economic cooperation and development (oecd). nine concentrations of zno nps (10, 50, 100, 500, 1000, 2000, 3000, 4000, and 5000 mg/l) were prepared in deionized )di( water (co...

plant performance and freshness is related to the pattern of its root growth development, which is highly affected by the water amount and water use management. therefore, the spatiotemporal variation of maize root under five treatments including full irrigation treatment (fi), partial root-zone drying treatments at two levels (receiving 75% of et =prd75, and 55% of et= prd55) and deficit irrig...

this study was conducted to investigate the effects of applying deficit irrigation on aboveground biomass, leaf area and root biomass for maize hybrid 704 single-cross. experimental treatments included 4 different irrigation levels, 5 growth stages with three replicates in a completely randomized factorial statistical design. aboveground biomass, leaf area and root biomass in 4 longitudinal sec...

in order to investigate the effects of plant growth promoting bacteria on growth characteristic of wheat, an experiment was conducted at the research greenhouse, faculty of agriculture, ferdowsi university of mashhad, iran, in year 2009. a completely randomized design based on factorial arrangement (3×6) with three replications was used. the first factor consisted of three cultivars of wheat (c...

The aims of the present study were to investigate the effect of Gokshura and nettle root extracts on growth rate and sex reversal in Convict cichlid fish. Seven-day hatchlings were immersed in water containing 0 (Control, T1), 200 mg/l nettle root extract (T2), 300 mg/l nettle root extract (T3), 10 mg/l Gokshura extract (T4) and 10 mg/l Gokshura plus 200 mg/l nettle root extracts (T5) for two m...

BACKGROUND Methods exist to quantify the distribution of growth rate over the root axis. However, non-destructive, high-throughput evaluations of total root elongation in controlled environments and the field are lacking in growth studies. A new imaging approach to analyse total root elongation is described. SCOPE High pixel resolution of the images enables the study of growth in short time i...
