| Abstract:
Salt stress is considered as one of the most important abiotic factors limiting plant growth and yield in many areas of the world. It has been shown that vesicular arbuscular mycorrhizal (VAM) fungi decrease plant yields losses under salinity. The effects of VAM Glomus etunicatum inoculation on growth and mineral acquisition of Pistacia vera L. grown under salinity condition was studied. Different concentrations of NaCl as 0 (control), 50 (low), 100 (medium) and 200mM (high) were employed for salinity stress. Plants were grown in a sterilized, low-P sandy soil in a greenhouse. It appeared that mycorrhizal colonization was higher in the control than in salin soil condition. Dry weight of shoots, roots and also leaf area of Mycorrhizal (M) plants were higher than Nonmycorrhizal (NM) ones in both control and salinity conditions. The contents of P, K, Cu and Zn were higher in M than NM plants in control, low and medium salinity conditions. Concentration of Na in shoots of M plants was lower than NM grown under salinity condition. Generally, it can be said that M plants of Pistacia vera showed higher tolerance toward salinity than NM plants and their growth improved by VAM colonization. | |
