The aim of this study is to determine the percentage of loss in yield of some durum wheat varieties against wheat leaf rust, and to identify whether the slow rusting has a positive effect in limiting yield loss. The study was carried out in the field
s of experiments at Faculty of Agriculture, Aleppo University, Aleppo, Syria, 2015, included six durum wheat varieties (Cham1, Cham5, Douma1, Cham9, Beltagy and Massine).
We studying in this research the reaction with Zinc sulphate in an
aqueous solution by physical - chemical method in presence of
Succinic Acid , and determined compounds which are formed in
this solution and we calculated of it formation the const
ants.
After we used these electrolytes in plating by Zinc , that is by
electro precipitation of this metal on the solid electrodes (steel,
copper) so that we definite the best of these electrolytes for galvany
and the set necessary conditions for its use.
Yellow rust caused by Puccinia striiformis f.sp. tritici is one of the most important
disease affecting wheat worldwide. The objective of this study was to evaluate
some morphological and productivity characteristics of durum and soft wheat
collected from different locations of Syria.
