The effective use of arbuscular mycorrhizal (AM) fungal function to promote host plant phosphate uptake in agricultural practice requires the accurate quantitative evaluation of AM fungal infection potential in field soil or AM fungal inoculation material. The number of infection units (IUs), intraradical fungal structures derived from single root entries formed after a short cultivation period...

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...

INTRODUCTION The aim of this study was to assess the radiographic technical quality of root canal therapy performed by fifth year students of Dental School of Hamadan University of Medical Sciences from 2015 to 2016. METHODS AND MATERIALS Four hundred and seventy records of root canal therapies were evaluated. Records with graphies taken as initial, master apical file (MAF), master apical con...

To determine root growth and grain yield of winter wheat (Triticum aestivum L) under moderate drought stress, a nursery experiment and a field trial were conducted with or without water stress using three representative cultivars released in different years: CW134 (old landrace), CH58 (modern cultivar) and CH1 (new release). In the nursery experiment, plants were grown in soil-filled rhizoboxes...

The purpose of this study was to assess the effects of increasing initial population density (Pi) of Meloidogyne incognita on nematode reproduction and growth of susceptible tomato (Lycopersicom esculentum cv. Round-41) at 25°C± 2 in growth chamber. 21-days-old tomato seedlings transplanted in13-cm dia. earthen pot was inoculated with Pi including 250, 500, 1000, 1500 eggs of M. incognita. Nema...

Simple expressions allowing estimation of the turbulent density perturbation from the reflectometry phase root mean square (r.m.s.) measurements and accounting for the turbulence correlation length are given. The numerical procedure for precise turbulence radial profile reconstruction for different turbulence wave number spectra and both O-mode and X-mode reflectometry is proposed. It is valida...

introduction : proper apical seal and obturation density are essential to long-term success of root canal therapy (rct). the apical seal and density of lateral compaction techniques using stainless-steel and nickel-titanium spreaders and vertical compaction with beefill device were compared in this in vitro study. materials and methods: a total of 66 extracted maxillary central incisors were in...

The research has been done for assessment of effects of different concentrations of Indole-3-Butyric Acid (IBA) on rhizogenesis of scions of C. Phlomidis in 2010.  The research has been done on Randomized Complete-blocks for five replications and three treatments with zero, 2000ppm and 3000pmm concentration. Different characters such as number of root of each scion, length of root, length of ne...
