Abstract
In order to investigate the effect of Mycorrhizal fungi and phosphorus fertilizer on concentration of leaf nutrients and photosynthetic pigments of bean (Phaseolus vulgaris L.) in condition of irrigation with saline water, an experiment was conducted based on completely randomized design with three replications in greenhouse of Bahonar University of Kerman, Iran during 2010. The studied factors were water salinity (500 (control), 2000, 4000 and 6000 s.cm-1), phosphorus fertilizer (0, 100 and 200 mg.kg-1 soil) in form of Triple super phosphate and mycorrhizal fungi with three levels (GLOMUS MOSSEAE AND GLOMUS INTRARADICES AND no fungi (control)). The results showed that the concentrations of chlorophyll a, chlorophyll b, total chlorophyll, carotenoeids, K, Ca and P were decreased with increasing of salinity levels. But salinity increased the concentration of Na and Na/K ratio. Mycorrhizal fungi had no significant effect on concentration of Ca and chlorophyll a. The interaction of salinity and phosphorus fertilizer on concentration of chlorophyll b, Na and P was significant. Results demonstrated that GLOMUS INTRARADICES had better effect on improvement of photosynthetic pigments concentration and concentration of nutrition elements. In low levels of salinity stress, use of MYCORRHIZAL FUNGI WITH PHOSPHORUS FERTILIZER, can reduce the negative effects of salt by increasing of concentration of photosynthetic pigments and nutrition elements.
