Effects of the application potassium silicate (PS) and an arbuscular mycorrhiza fungus (AMF) (Glomus mosseae) were investigated on alleviating impacts drought stress Matthiola incana in a split-split-plot experiment two consecutive years. The main plot was assigned to at three levels irrigation (25%, 50%, 70%, field capacity) comparing with control (100% sub-plots AMF (0 200 g fungi pots) sub-s...

introduction: arsenic is a highly toxic metalloid in group 15 of periodic table. the information on environmental behaviour of arsenic, however, is still scarce. contamination of soils and water with arsenic and antimony due to their widespread industrial application and mining activities has raised serious environmental concerns. nearly all arsenic-contaminated soils results from human activit...

The diversity of arbuscular mycorrhizal fungi (AMF) in 10 Oregon vineyards was assessed by examining spores in soil and amplifying mycorrhizal DNA from roots. Seventeen spore morphotypes were found in soil, including seven species in the Acaulosporaceae. Eighteen phylotypes were amplified from grape roots with AM1 and NS31 primers, and clones were dominated by Glomus spp. (> 99%). A few clones ...

Abstract Lisianthus (Eustoma grandiflorum) is an ornamental species used as a potted plant or cut flower, its popularity due to the diversity of colors, number flower buds, and shelf life. Nevertheless, during first phases development, problems such foliar chlorosis root diseases affects most cultivars, causing poor growth, thin stems, few flowers. The use growth-promoting rhizobacteria (PGPR) ...

The colonization of an arbuscular mycorrhizal fungus Glomus intraradices BEG110 in the soil caused a decrease in disease severity in cucumber plants after fungal inoculation with Colletotrichum orbiculare. In order to illustrate the resistance mechanism mediated by G. intraradices BEG110, infection patterns caused by C. orbiculare in the leaves of cucumber plants and the host cellular responses...
