Could indigenous arbuscular mycorrhizal communities be used to improve tolerance of pistachio to salinity and/or drought?

Popis výsledku v původním jazyce

Arbuscular mycorrhizal fungi (AMF) establish symbiosis with a number of plant species, including pistachio, under a broad range of soil conditions. Here we present a fully factorial pot experiment where four different indigenous AMF communities (two with high- and two with low-salinity legacies) were tested for improving pistachio seedling tolerance to salinity and/or drought in terms of maintaining its growth and/or mineral (phosphorus and zinc) nutrition under experimentally applied abiotic stress. The AMF communities were pre-cultured with a grass to reduce the load of pistachio pathogens before application to the seedlings. We detected systematic improvement of pistachio mineral nutrition by the AMF communities, whereas salinity and drought generally suppressed pistachio performance independently of each other. The AMF communities from saline soils systematically improved pistachio tolerance to salinity in terms of maintaining higher phosphorus acquisition of their host, whereas their effect on maintaining plant zinc nutrition under high salinity was less prominent. The effects of the different AMF communities on pistachio tolerance to drought were variable and without obvious link to the environmental legacy of the AMF. One of the AMF communities from saline soil (dominated by Rhizophagus) showed particular tolerance to salinity in terms of maintaining high colonization rates of pistachio roots. Interestingly, one of the AMF communities from low-salinity soils conferred a significant tolerance of pistachio to salinity in terms of maintaining its phosphorus acquisition upon the stress. This means that beneficial traits of plant symbiotic microbes may occur uncoupled from the selective pressure in their native range.
