Abstract
The effects of the presence or absence of Mg in the nutrient solution and of vesicular-arbuscular mycorrhizal fungi (VAMF) on the content and partitioning of Ca, K and P between root and shoot of date palm (Phoenix dactylifera) seedlings were examined under greenhouse conditions using soil as basal medium. Mg content of the soil was 14.95 μmol/g dry soil. The infection percentages after inoculation of VAMF were 66.0% and 55.5%, respectively, on application of –Mg and +Mg nutrient solution. Ca content of both roots and shoots did not change by these treatments; but a highly significant decrease in shoots was recorded on –Mg and +VAMF treatment, K content of root was significantly elevated by –Mg and +VAMF treatment but no changes were observed in shoots. P content of both roots and shoots increased significantly with +VAMF regardless of the presence or absence of Mg.
