Previously, Ruiz-Lozano and Azcón [27], found that one mechanism of Glomus sp. -inducedsalt stress amelioration is stimulating root growth of the host plant. However, possible effects ofAMF on root biomasses under moderate salt stress and/or root: shoot (R:S) ratios were not visible,possible due to the limited growth period after transplanting. Overall, we have not found anysignificant difference in root to shoot ratios between transplanted AMF+ and AMF seedlings withor without salt stress, while Abdel Latef and He Chaoxing [11] found AM fungi’s effect on dry matteraccumulation in tomato was more pronounced on aboveground biomass rather than on root biomassand thus changed the R:S ratio. Further experiments, possible under different nutrient supply andincluding different varieties, are needed to clarify these findings. However, since RGRRoots and root biomass of inoculated (AMF+) plants remains more stable under most saline soil conditions,nursery inoculation with arbuscular mycorrhizae spores will benefit stand establishment of the testedtomato variety.Salinity influences total nitrogen (N) uptake [48] and as well as interferes at different stages of itsmetabolism [46]. N and C concentrations and C:N ratios are positively correlated with RGR [49,50].In addition, previous studies have reported that improved N nutrition may help to reduce the toxiceffects of Na ions by reducing its uptake and this may indirectly help in maintaining the chlorophyllcontent of the plant [21]. Because AM fungi can function as facilitator for N uptake [48], a higherleaf N content was found in AMF+ transplanted tomato seedlings and consequently higher or at leastmore stable growth rates (RGRRoot and RGRPlant, respectively) were achieved in the first seven daysafter transplanting.
