conclusions allium hirtifolium and z. spina-christi extracts showed the most efficient activity in the inhibition of promastigote growth, but this was not total. the remaining plant extracts indicated ineffective or very weak efficiency on the leishmania promastigotes. there is a possibility of achieving better results by changing the extraction method; determining materials affecting promastig...

Influence of arbuscular mycorrhizal fungi (AMF) (Glomus etunicatum, G. intraradices and Glomus versiforme) and external phosphorus supplement (8 and 35 mg P Kg-1 soil) on leaf P, Zn, Cu and Fe nutrition of 4-month-old tea(Camellia sinensis) was studied in an glass house pot experiment. The highest leaf P concentration (up to 59.43% increase) was found in G. versiforme inoculated seedlings gro...

Ganoderma colossum is a rare species of Ganodermataceae family with many biological and biochemical properties. It is associated with rot, wilt, dieback, and wood decay of many host plants such as Ficus carcica, Celtis laevigata, Pinus hondurensis, Callitris robusta, Eucalyptus citrodora, E. paniculata, E. puncata, and Phoenix canariensis. In Oman, this pathogen was isolated as new records from...

KRAIGHER H. & HANKE D.E. 1996. Cytokinins in Norway spruce seedlings and forest soil pollution. Phyton (Horn, Ausrtia) 36 (3): (57) (60). Cytokinins can correlate with pollution damage in spruce trees and also with different strains and species of their mycorrhizal symbionts. In our study, Norway spruce seedlings were grown in vitro on sterilized or nonsterile soil substrates from two different...

The purpose of this study was to understand how the addition Ziziphus spina–christi and Cinnamomum zeylanicum essential oils as antimicrobial agents affect microbiological properties braided cheese. Cheese made from warmed (45℃) raw cow milk which Z. C. (0.3% 0.5%) were added. Microbiological characteristics determined at 1, 7, 14 21-day intervals. significantly reduced counts total viable bact...

We initiated a study of the effects of mycorrhizal fungal community composition on the restoration of tropical dry seasonal forest trees. Tree seedlings were planted in a severely burned experimental site (1995 fire) during the growing season of 1998 at the El Edén Ecological Reserve, in north Quintana Roo, Mexico. Seedlings of Leucaena leucocephala, Guazuma ulmifolia, Caesalpinia violacea, Pis...

As a potential phytoremediation system for phytoextraction of chromium (Cr), we evaluated the influence of the arbuscular mycorrhizal fungus Glomus intraradices on leaf tissue elemental composition, growth and gas exchange of sunflower (Helianthus annuus L.). Sunflower seedlings were either inoculated with mycorrhizal fungi (AM) or non-inoculated (Non-AM) and then exposed to two Cr species: {12...

Malaria is still taking the lead as one of the deadliest infectious diseases worldwide, appealing continuous research for further understanding the biology and the pathogenesis of this fascinating parasite. Discovering effective alternative drugs, however, remains a challenging task to address today’s enigmatic problem, the emergence of resistant strains. Factually, the presence of potent natur...

We investigated the impact of arbuscular mycorrhizal fungi (AMF) on the morphology and physiology of two genders of the typical dioecious plant Populus cathayana under salt stress. We conducted a pot experiment containing seedlings of the two genders that were subjected to salt or non-salt and filled with soil that was either inoculated with Rhizophagus intraradices or not. The results showed t...
