Synergistic Effect of ZnO NPs and salicylic acid on Chlorophyll a, b and Carotene content of wheat (Triticum aestivum L) leaves
Abstract
The aim of this study economic feasibility of using available materials, inexpensive and
environmentally friendly as fertilizers for wheat plants .also, Increasing wheat yield by improving the
overall vegetative and physiological characteristics. The experiment was for the wheat plant
cultivars utilizing two types, IPA99 and Abograib. plants sprayed with three different concentrations
of ZnoNPs & SA (0, 50, 75, and100) ppm in three different Treatments,T1 foliar spraying SA , T2
foliar spraying ZnoNPS , and T3 foliar spraying SA & ZnoNP. The results showed the best effect of
T3 at75 ppm on the Chlorophyll a, Chlorophyll b and Carotene on IPA99 cultivar, on the other hand
T1 display better effect on Chlorophyll a, Chlorophyll b and Carotene on both cultivars. while ,T3
at 100 ppm show less effects on both cultivars compared to the other treatment.
