Abstract The genus Ziziphus is cultivated worldwide mostly for its medicinal purposes aside from edible fruits due to diverse phytochemicals. grown in several world locations encompass mainly Z. jujuba, xylopyrus , spina-christi lotus mauritiana celata, etc. Folk uses reported include treating headaches, obesity, common colds, diabetes, hypertension, and infections.

To test the hypothesis that elevated atmospheric CO # and elevated temperature, simulating current and predicted future growing season conditions, act antagonistically on phosphorus acquisition of ponderosa pine, seedlings were grown in controlled-environment chambers in a two temperature (25}10 °C and 30}15 °C)¬two CO # (350 and 700 μl−") experimental design. Mycorrhizal seedlings were watered...

Abstract In order to investigate temporal variation in the arbuscular mycorrhizal (AM) fungal community in a tropical forest in the Republic of Panama, seedlings of the canopy emergent Tetragastris panamensis were sampled three times over a period of 3 years. We used AM-specific primers to amplify and clone partial small subunit ribosomal RNA gene sequences. Over 550 clones were classified into...

1 The e€ects of wild®re ash on ectomycorrhizal (EM) associations were investigated by sampling bishop pine (Pinus muricata, D. Don) seedlings from control and ash-removed plots 1.5 years after a severe ®re in a northern Californian P. muricata forest. The below-ground community composition of EM at the site was characterized using molecular techniques (PCR-RFLP and nucleotide sequencing). 2 A t...

Mechanistic hypotheses to explain mycorrhizal enhancement of root hydraulic conductivity (L,) suggest that phosphorus (P) nutr i t ion, plant growth substances and/or al tered morphology may be responsible . Such ideas are based on work with VA (vesicular-arbuscular) mycorrhizas . S ince VA mycorrhizas and ectomycorrhizas di f fer in many respects , they may alter host plant water uptake via di...

Commercial production of tree seedlings often includes various biocidal soil treatments for disease control. Such treatments can be effective in eliminating or reducing disease organisms in the soil, but may also eliminate non-targeted beneficial soil organisms, such as mycorrhizal fungi, that improve seedling performance, both in the nursery as well as the outplanted environment. The arbuscula...

Drought stress has become an increasingly serious environmental issue that influences the growth and production of watermelon. Previous studies found that arbuscular mycorrhizal (AM) colonization improved the fruit yield and water use efficiency (WUE) of watermelon grown under water stress; however, the exact mechanisms remain unknown. In this study, the effects of Glomus versiforme symbiosis o...
