Investigation of the effects of endomycorrhizal fungi on mineral nutrition and growth of Pistachio (Pistacia very L.) in salt stress condition

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 can alleviate this deficiency. The effects of VAM inoculation on growth and mineral nutrition of Pistacia vera L. in salt stress condition were studied. Plants were grown in a sterilized, low-P sandy soil with Glomus etunicatum inoculum (12 spore/g soil) in greenhouse. RLC (Root Length Colonized) was higher in control plants than treated plants with different salt concentration. Shoot and root dry weight and also leaf area of mycorrhizal (M) plants were higher than nonmycorrhiza (NM) ones in both control and salt stressed plants. P, K, Cu and Zn content were higher in M than NM plants in control, low and medium salinity conditions but concentration of Na was lower in anal parts of the M plants. Results showns a higher tolerance of inoculated pistachio to the salt stress and more growth.
