in chapter 1, charactrizations of fragmentability, which are obtained by namioka (37), ribarska (45) and kenderov-moors (32), are given. also the connection between fragmentability and its variants and other topics in banach spaces such as analytic space, the radone-nikodym property, differentiability of convex functions, kadec renorming are discussed. in chapter 2, we use game characterization...
abstract governing was disorganized for years, when mongols attached to iran and it caused to clearing way for interference of mongols princes. dispatching of holaku to the west culminated in establishing iilkhanan government. holakus activities in destruction of abbaasis government and activities which shows his staying in iran, made force oulus juji to comparison against iilkhanis gover...
the research aims at studying the effects of mycorrhizal fungi (glomus fasciculatum, g. mosseae and mixed composition) on growth, photosynthesis and nutrient absorption of ziziphus spina-christi in mehran greenhouse, ilam province. the result showed that colonization rate in mixed treatment was more than pure treatment of g. fasciculatum and g. mosseae. also, root fresh weight, stomatal conduct...
Advances in ecology during the past decade have led to a much more detailed understanding of the potential negative consequences of species' introductions. Moreover, recent studies of mycorrhizal symbionts have led to an increased knowledge of the potential utility of fungal inoculations in agricultural, horticultural and ecological management. The intentional movement of mycorrhizal fungal spe...
Elaeagnus angustifolia L. is a drought-resistant species. Arbuscular mycorrhizal symbiosis is considered to be a bio-ameliorator of saline soils that can improve salinity tolerance in plants. The present study investigated the effects of inoculation with the arbuscular mycorrhizal fungus Rhizophagus irregularis on the biomass, antioxidant enzyme activities, and root, stem, and leaf ion accumula...
The intraradical portion of arbuscular mycorrhizal (AM) fungi comprises mycelium, vesicles, and special physiological interfaces termed arbuscules; sometimes mycorrhizal fungi also produce spores within their hosts. Arbuscules are ephemeral structures that collapse after a few days, while the hyphae and vesicles appear to remain intact for some time after arbuscule senescence (post-arbuscule st...
The influence of endophyte fungus piriformospora indica on characteristics of the growth, water status, photosynthetic pigments concentration, gas exchange, and chlorophyll fluorescence of tomato plants under salt stress (0, 50, 100 and 150 mM) was studied in the greenhouse. Under salt stress, mycorrhizal tomato plants had higher dry weight of shoot and root, higher height, higher carotenoid an...
BACKGROUND Global phosphorus (P) reserves are being depleted, with half-depletion predicted to occur between 2040 and 2060. Most of the P applied in fertilizers may be sorbed by soil, and not be available for plants lacking specific adaptations. On the severely P-impoverished soils of south-western Australia and the Cape region in South Africa, non-mycorrhizal species exhibit highly effective a...
in order to examine the effects of biological and chemical fertilizers with the use of salicylic acid on the agronomic characteristics of corn as a factorial experiment in randomized complete block design with three replications at the agricultural research station in 2011 was boroujerd. factors examined included three levels of phosphorus fertilizer (0, 100 and 150 kg ha), two levels of biolog...
The apoplastic permeability of the fungal sheath of two different ectomycorrhizal associations of Pinus sylvestris L. was analysed by laser microprobe mass analysis (LAMMA) and energy-dispersive X-ray spectroscopy (EDXS) after stable isotope labelling with 25Mg, 41K and 44Ca. Entry of 25Mg and 44Ca into the outer cortical apoplast of non-mycorrhizal roots was detected after 4 min of labelling. ...
