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...

The aims of this study were to investigate genotypic variations in root traits at phytomer level of wheat varieties and for recommending a few root traits as selection parameters in future breeding programs. Two separate experiments were conducted to measure their root traits for hydroponically grown wheat plants. In Experiment 1, main axis length, root hair density and diameter differed from p...

in order to investigate the effect of concentration, time and consumption instruction of seaweed on some morphological characteristics of root and shoots of safflower, the present experiment in factorial form in a completely randomized design with three replications in research greenhouse of agriculture faculty, ferdowsi university of mashhad was conducted in 2014-15. factors examined included ...

background: the aim of the present study was to investigate the quality of root canal obturation performed by 6th year undergraduate dental students at the dental school, university of mashhad, iran. materials and methods: a random 200 sample records of patients who received endodontic treatment at the dental school, university of mashhad between 2009 and 2010 was investigated. the quality of r...

abiotic stresses and lack of nutrients are one of the most important factors in reducing the crop yield.  vigorous and developed roots can facilitate uptake of water and nutrients more efficiently making it essential for enhancing the yield. association mapping is currently one of the approaches for detecting quantitative trait loci (qtls) influencing complex traits. this approach was used to d...

Due to the importance of Acer monspessulanum in Iranian mountain forests, a study was carried out to reliably estimate its woody biomass and growing volume via allometric equations. Four transects, five trees in each were chosen randomly. The characteristics of standing trees including: diameter at root collar, height, number of stems and crown width were measured, then trees were finally cut d...

BACKGROUND AND AIMS Root diameter, especially apical diameter, plays an important role in root development and function. The variation in diameter between roots, and along roots, affects root structure and thus the root system's overall foraging performance. However, the effect of diameter variation on root elongation, branching and topological connections has not been examined systematically i...
