This study investigated the effects of increasing CaCO3 concentrations (0, 5, 10, 20 mM) on arbuscular mycorrhizal (AM) symbiosis establishment as well as on chicory root growth and mineral nutrient uptake in a monoxenic system. Although CaCO3 treatments significantly decreased root growth and altered the symbiosis-related development steps of the AM fungus(More)
The efficiency of two mycorrhizal bio-inoculants on the mineral uptake during the growth stages of a Mediterranean forage legume sulla (Hedysarum coronarium L.) was studied in the field on a highly calcareous soil. The first inoculum (Mm) was made up of a mixture of native arbuscular mycorrhizal fungi (AMF) isolated from calcareous soils: Septoglomus(More)
A total of 45 bacteria were isolated from root nodules of sulla (Hedysarum coronarium L.) in Tunisia and tested for their tolerance to NaCl, alkaline pH and PEG-induced water stress. Tolerance limits varied from 150 to 700 mM for NaCl, from 9 to 10.5 for alkaline pH and from −0.5 to −0.95 MPa for PEG-induced stress. Three effective isolates with variable(More)
Th is paper seeks to shed light on the eff ect of temperature on fi eld bean (Vicia faba L. var. minor) germination and root elongation. Accordingly, the results were as follows: germination was faster at 20°C than at 5, 10, 15, 25 or 30°C. However, temperature had no eff ect on total germination percentage between 10 and 30°C, although it was reduced by(More)
