SUMMARY Wheat cultivars inoculated with Glomus mosseae show different degrees of mycorrhizal infection and dependency. Mycorrhizal dependency was affected by root root/shoot (R/S) ratio dry wts, but neither nor levels were directly N, P, K, Ca or Mg concentrations in plant tissues. Absence some wheat varieties associated lack sugar exudation from the roots rather than content roots. VA led to a decrease reducing total extracts, this effect correlated degree infection.
The tolerance of lettuce plants (Lactuca sativa L. cv. Romana) to drought stress differed with the arbuscular-mycorrhizal fungal isolate which were associated. Seven species belonging genus Glomus studied for their ability enhance plants. These fungi had different traits that affected resistance host ranking effects on tolerance, based relative decreases in shoot dry weight, was as follows: deserticola > fasciculatum mosseae etunicatum intraradices caledonium occultum. In this comparative...
Vesicular‐arbuscular mycorrhizae may increase resistance of plants to drought by a number mechanisms, such as increased root hydraulic conductivity, stomatal regulation, hyphal water uptake and osmotic adjustment. However, substantial contribution vesicular‐arbuscular mycorrhizal (VAM) hyphae has not been demonstrated unequivocally. The objective this investigation was examine the from two VAM fungi transport host plant. Lettuce ( Lactuca sativa L.) were grown in container divided screen...
The interactive effect of phosphate-solubilizing bacteria and arbuscular mycorrhizal (AM) fungi on plant use soil P sources low bioavailability (endogenous or added as rock phosphate [RP] material) was evaluated by using microcosms which integrated (sup32)P isotopic dilution techniques. microbial inocula consisted the AM fungus Glomus intraradices two rhizobacterial isolates: Enterobacter sp. Bacillus subtilis. These rhizobacteria behaved "mycorrhiza helper bacteria" promoting establishment...
SUMMARY The significance of the external mycelium arbuscular mycorrhiza for uptake and transport N from 15 N‐labelled nitrate in benefiting plant nutrition, was evaluated under either well‐irrigated or water‐stressed conditions. Plants lettuce ( Lactuca sativa L.) were grown controlled conditions a neutral agricultural soil/sand mix non‐mycorrhizal association with arbuscular‐mycorrhizal fungus, Glomus fasciculatum (Taxter sensu Gerd.) Gerd. Trappe. pots comprised two‐compartment system,...
It is currently accepted that, along with nutrients, arbuscular mycorrhizal (AM) fungi also transport water to their host plant. However, the quantity of supplied and its significance for plant relations remain controversial. The objective this work was evaluate compare ability six AM alter rates root uptake under drought stress conditions. Soil drying uninoculated control plants comparable size nutritional status were recorded daily. Lactuca sativa colonized by Glomus coronatum , G....
Improved salt tolerance of mycorrhizal plants is commonly attributed to their better mineral nutrition, particularly phosphorus. However, the effect arbuscular‐mycorrhizal (AM) fungi on may not be limited this mechanism. We investigated possibility that non‐nutritional effects AM fungi, based proline accumulation or increased photosynthesis and related parameters, can influence lettuce ( Lactuca sativa L.) salinity. Three levels (3, 4 5 g NaCl kg ‐1 dry soil) were applied maintained under...
• Drought stress causes premature senescence in legume root nodules, therefore decreasing their ability for nitrogen fixation. Many physiological plant processes affected by drought have also been proposed as inducers of nodule senescence. The objective this research was to determine whether arbuscular mycorrhizal (AM) symbiosis, already proven protect host plants against the detrimental effects drought, can help cope with induced stress. Several parameters related were evaluated well...
