Phytoremediation of volatile organic compounds in indoor air involves both the plant and microbes in the media; however, removal rate is typically expressed on a leaf area basis. We determined the effect of root media volume on phytoremediation rate of volatile toluene and xylene to determine if there is a change in phytoremediation efficiency. Phytoremediation rate was calculated based on the ...

in order to determine the effect of different irrigation intervals on some morphophysiological traits of basil (ocimum basilicum l.), an experiment was conducted as factorial based on randomized complete block design with three replications under greenhouse conditions during 2010. treatments included five irrigation intervals with 4, 8, 12, 16 and 20 days intervals and two ecotypes of basil (gr...

An association mapping panel, named as CIMMYT Asia association mapping (CAAM) panel, involving 396 diverse tropical maize lines were phenotyped for various structural and functional traits of roots under drought and well-watered conditions. The experiment was conducted during Kharif (summer-rainy) season of 2012 and 2013 in root phenotyping facility at CIMMYT-Hyderabad, India. The CAAM panel wa...

An automated method for root system architecture reconstruction from 3D volume datasets obtained from magnetic resonance imaging is developed and validated with a 3D semi-manual reconstruction using virtual reality and a 2D reconstruction using SmartRoot (Lobet et al., 2011). It is tested on the basis of a MRI image of a 25 days old lupin grown in natural sand with a resolution of 0.39× 0.39× 1...

BACKGROUND It has been shown that L4/L5 selective nerve root blocks become nonselective after injecting 1 mL and 0.5 mL of contrast. Volumes of less than 0.5 mL have not been used to determine a volume of definite specificity. OBJECTIVE This study attempts to identify the minimum volume of contrast at which selectivity is maintained without spread to the superior or inferior end plate. STUD...

Knowledge is limited about whether root nutrient concentrations are affected by mixtures of tree species and interspecific root competition. The goal of this field study was to investigate root nutrient element concentrations in relation to root and ectomycorrhizal (EM) diversity in six different mixtures of beech (Fagus sylvatica), ash (Fraxinus excelsior) and lime (Tilia sp.) in an old-growth...

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...
