The effects of Arbuscular Mycorrhizal fungi on nitrogen concentration of berseem clover were examined in contaminated soil with cadmium. Examined factors included: levels of arbuscular mycorrhizal fungi inoculation (Glomus mosseae) (With and without inoculation), and different levels of soil contamination by cadmium (0, 5, 10, 20, 40 and 80 mg.kg-1). The results showed that the effects of cadmi...

abstract to evaluated oryza2000 model in iran, this study was carried out during 2004 till 2007 at rice research institute of iran, rasht. the experiment was conducted as split plot in complete randomized block design and three replicates. three irrigation levels were the main plots and four levels of n application were allocated sup-plots model. simulated and measured values leaf area index (l...

Riparian plants in arid regions face a highly variable water environment controlled by hydrological processes. To understand whether riparian plants adapt to such environments through plastic responses, we compared the root traits, biomass allocation and growth of Populus euphratica Oliv. Seedlings grown in lysimeters filled with clay or clay/river sand sediments under inundation and varying wa...

A pot experiment examined the biomass and As uptake of Medicago truncatula colonized by the arbuscular mycorrhizal (AM) fungus Glomus mosseae in low-P soil experimentally contaminated with different levels of arsenate. The biomass of G. mosseae external mycelium was unaffected by the highest addition level of As studied (200 mg kg(-1)) but shoot and root biomass declined in both mycorrhizal and...

Stable carbon isotopes are used extensively to partition total soil CO2 efflux into root-derived rhizosphere respiration or autotrophic respiration and soil-derived heterotrophic respiration. However, it remains unclear whether CO2 from rhizosphere respiration has the same δC value as root biomass. Here we investigated the magnitude of C isotope fractionation during rhizosphere respiration rela...

Miscanthus holds a great potential in the frame of bioeconomy, and yield prediction can help improve Miscanthus’ logistic supply chain. Breeding programs several countries are attempting to produce high-yielding hybrids better adapted different climates end-uses. Multispectral images acquired from unmanned aerial vehicles (UAVs) Italy UK 2021 2022 were used investigate feasibility high-throughp...

an ability of the fluorescent pseudomonad bacteria is to secrete such secondary metabolites as hydrogen cyanide, protease, salicylic acid as well as siderophore which prevent the growth of soil-habitant pathogens. tests were done for evaluating the materials produced by the said bacteria. in the tests' cultures, p. aeruginosa strains 7nsk2, utpf92, and utpf86 produced the most hydrogen cya...

BACKGROUND AND AIMS Phosphate (Pi) deficiency in soils is a major limiting factor for crop growth worldwide. Plant growth under low Pi conditions correlates with root architectural traits and it may therefore be possible to select these traits for crop improvement. The aim of this study was to characterize root architectural traits, and to test quantitative trait loci (QTL) associated with these...

Root biomass distributions have long been used to infer patterns of resource uptake. These patterns are used to understand plant growth, plant coexistence and water budgets. Root biomass, however, may be a poor indicator of resource uptake because large roots typically do not absorb water, fine roots do not absorb water from dry soils and roots of different species can be difficult to different...
