e0“Mycorrhizal (+M) plants maintained greater root and shoot biomass at all salinity levels compared to non-mycorrhizal (-M) plants”
e1“In a greenhouse experiment, plant growth and rates of uptake and root to shoot transport of chloride and sodium were investigated in seedlings of pistachio (Pistacia vera cv. Badami-Riz-Zarand) inoculated with Glomus mosseae and exposed for 21 and 42 days with four salinity levels (0.5, 3.0, 6.0 and 9.0 dSm-1).”
e3“In -M plants, salt intensity had no significant effect on shoot dry weight (SDW) and leaf dry weight (LDW) on each of harvesting dates but root dry weight (RDW) showed a significant decrease at the highest salinity level 42 days after the start of salt treatment (DAT) in comparison with control (EC of 0.5 dSm-1).”
e4“In +M plants, SDW was increased with an increase in salt intensity especially in the first harvesting date.”
e5“In conclusion, the study indicates that pistachio tolerance to salt stress is improved by mycorrhizal colonization, although the salinity levels used in this work could not induce biomass reduction in -M pistachio plants, higher levels of salinity should be investigated in order to optimize the effect of this symbiosis.”

Other claims from this paper (9)
- Intervention effect Salinity did not significantly change shoot or leaf dry weight in nonmycorrhizal plants.
- Intervention effect At the highest salinity after 42 days, root dry weight fell in nonmycorrhizal plants.
- Association Shoot dry weight increased with salinity in mycorrhizal plants, especially at the first harvest.
- Association Root dry weight also increased with salinity in mycorrhizal plants.
- Intervention effect Leaf dry weight did not respond to salinity in mycorrhizal plants.
- Intervention effect Mycorrhizal plants had lower chloride and sodium uptake and root to shoot transport.
- Intervention effect Mycorrhizal colonization reduced chloride and sodium accumulation.
- Observation The authors concluded that mycorrhizal colonization improves pistachio salt tolerance.
- Recommendation The authors recommended testing higher salinity levels.
