Abstract
The experiment was conducted to study role of potassium and calcium mixture to reduce salt stress of some genotypes of wheat: This experiment included three factores the first factor was three levels of potassium and calcium 0Ca + K , 500Ca+ 1000 K and 1000Ca +2000K (µM).L-1. The second factor was three levels of salinity at 1.4 ds/m , 4 ds/m and 8 ds/m-1 .Third factor was four varieties of wheat: Sin Al-Fel, Ibaa 99, Jandola and Abu Ghraib, with three replications was adopted to be a number of experimental units(108).The result can be summarized as follow :- Sin Al-Fel variety was superior in values of activity antioxidant enzymes Peroxidase , Catalase , Superoxide dismutase , spikes number and weight of 1000 grains , while the second of durum wheat variety Jandola was superior in values of the proline concentration, grain number and potassium and phosphorus concentration. Ibaa 99 variety of soft wheat was superior in values of the antioxidant enzymes activity Peroxidase , Superoxide dismutase , grains number and potassium and phosphorus concentration, Abu Ghraib3 was superior in proline concentration , weight of 1000 grains 0Ca + 0 K treatment was superior to giving higher values in the antioxidant enzymes activity Peroxidase , Catalase , Superoxide dismutase and proline. This was the result of nutrition stress of potassium and calcium, while 500 Ca + 1000 K treatment was superior in giving higher values of spike number and weight of 1000 grain, while K 2000 +1000 Ca treatment was superior in giving higher values of
