الملخص EN

Paeoacremonium aleophilum W.

Gams, Crous has influences on nutrient elements in infected twig Apricot tissue.

The pathogen caused accumulation of Nitrogen and Phosphors after one month stating from inculcation with 35.969% increasing in Nitrogen for Abo-zyngeel Local Cultivar of inculcation while there was no Nitrogen increasing in the rest local cultivars.

Phosphors was accumulated only in Turkey local cultivar after two hours with 7.4%, while the other nutrient elements such as K,Ca,Fe did not record any significant increasing for all LCs.

All tested nutrient elements at their levels in infected tissue (Fe,P,Ca,N) except K had been inhibited P.

aleophilum dry weight in Minimal Medium while concentration (5000mg/L and 400mg/L) K and P had stimulated effect to fungus sporulation in contrasting to the inhibition effect on the rest nutrient elements including Fe,Ca,N at 400,4000,10000 mg/L levels respectively.

There are high correlation between salicylic acid high levels of Potassium and Phosphorus elements in the otherwise there are high correlation between salicylic acid and low levels with Calcium and Ferrous elements.
