This experiment aimed to study phosphorus efficiency of six wheat genotypes (Triticum aestivum) inoculated with arbuscular mycorrhizal fungi (AMF) and to quantify the contribution of root and mycorrhizal hyphae length to P uptake by using NST 3.0 model. The results showed that all wheat genotypes with AMF (except V4) attained more than 80% of the m...

Background Forty phosphate solubilizing bacterial (PSB) isolates were isolated from the root zone of wheat plants cultivated in the Delta and the Northwestern coast regions of Egypt. All isolates proofed their ability to dissolve tricalcium phosphate on the National Botanical Research Institute's phosphate growth medium (NBRIP) by producing clear z...

This work was conducted to study phosphorus (P) efficiency of two maize genotypes (Zea mays, L.) in calcareous soil grown in potted soil with two levels of P in soil by adding 40 and 270 mg P/kg soil. Half of the pots were inoculated with arbuscular mycorrhizal fungi (AMF) (Rhizoglomus irregulare). The maize genotypes were harvested two times at 35...

The response of radish plants to organics materials and inorganic fertilizers under sandy soil conditions was investigated. A pot experiment was conducted in the greenhouse at the Faculty of Agriculture, (Saba-Basha)-Alexandria University, Egypt during 2013-2014. Radish plants were treated with eight sources of organic materials (Sheep, rabbit, chi...

Pot experiments using calcareous soil, were carried out to study the influence of irrigation with diluted seawater on tomato (Strain B) plants growth as affected by compost application and mycorrhhiza inoculation during summer 2011 season. Four different irrigation water salinity levels (0.44, 2.70, 6.20, 12.50 dS/m), three different mycorrhizal tr...

Tomato Fusarium wilt disease caused by Fusarium oxysporum f. sp. Lycopercisi (FOL) is considered one of the most destructive diseases in Egypt. Effect of some biotic inducers such as Bacillus megaterium var. phosphaticum, Glomus intraradices and Glomus macrocarpum at seven different mixed treatments, was tested for their ability to induce resistanc...

A pot experiment was carried out in the greenhouse at the faculty of Agriculture (Saba Basha), Alexandria University, Egypt, to evaluate the response of onion and leek plants during the early growth stage to mycorrhizal inoculation on a phosphorus (P) deficient calcareous soil. The soil used in this work was collected from Burg El-Arab City, Alexan...

Potential mineral oil degrading bacterial isolates (Pseudomonas putida, Rhodococcus erythroplolis and Bacillus thermoleovorans) were studied from the contaminated soils. The bacterial populations of these polluted soils were 5.25 × 10 5 , 1.76 × 10 6 and 5.11 × 10 5 CFU/ml with three different colony types of bacterial strains, respectively. Microb...

The present work evaluated the synergistic effects of soil fertilization with rock P and K materials and co-inoculation with P and K-dissolving bacteria [PDB (Bacillus megaterium var. phosphaticum) and KDB (Bacillus mucilaginosus and B. subtilis)] on the improvement of P and K uptake, P and K availability and growth of maize plant grown under limit...

A pot experiment was carried out in a greenhouse at the Faculty of Agriculture (Saba-Basha)-Alexandria University in order to evaluate the effect of two species of mycorrhizae (Glomus intraradiaces (M1) and Glomus macrocarpium (M2)), two genera of bacteria (Bacillus subtilis (B1) and Pseudomonas fluorescens (B2)) and two genera of yeast (Cryptocooc...

This research aimed to study P efficiency of ten maize genotypes (zea mays, L.) under two levels of P in calcareous soil and to quantify the contribution of root growth in P uptake. Plants were grown in potted soil with two levels of available P in soil 40(low P) and 270 (high P) mg P / kg soil in glasshouse with five replicates in randomized compl...

Isolation, purification and identification White mold, caused by S. sclerotiorum (Lib.) de Bary, is a destructive yield- limiting disease of common bean (Phaseolus vulgaris L.) in Egypt. Forty eight isolates of Sclerotinia sp. were isolated from diseased bean tissues taken from 9 geographical regions at Al-Behaira, Alexandria and Assiut governorate...

Background: Androgenetic alopecia (AGA) occurs in men and women. The nature of the genetic predisposition to androgenetic alopecia is still unresolved. The aim of the work is to study the genotype of the androgen receptor gene (StuI polymorphism) and its relationship to AGA in a case control study and to determine the level of androgen receptor exp...

The objective of the present work was to examine the interaction between arbuscular mycorrhizal fungus (AMF) Glomus intraradices and Trichoderma harzianum in soil. Soil application with T. harzianum or/and G. intraradices significantly reduced tomato seedlings damping-off incited by Rhizoctonia solani. Moreover, more pronounced disease suppression...

This study was conducted to investigate the effect of blue green algae (BGA) and A-mycorrhizal fungi (AMF) inoculation (biofertilizations) and nitrogen application on growth yield and...

Plant species may differ in phosphorus efficiency. Phosphorus efficiency of plants may arise from enhanced ability of roots to acquire P from the soil or/and from high ability of shoots to produce yield per unit P acquired. This research was aimed at studying P efficiency of plants (carrot, onion, and leek), and to elucidate morphological root char...
