اثر عناصر غذایی ماکرو و میکرو بر برخی خصوصیات فیزیولوژیکی چهار ژنوتیپ یولاف زراعی در اهواز

This experiment was conducted to study Effect of macro and micro element nutrition on physiological changes of four genotypes of oat during 2013-2014 growing season as field experiment at research field of Agronomy and Plant Breeding Department of Shahid Chamran University of Ahvaz. Experimental design was split-plot based on RCB with three replications. Two factors were studied in this experiment. The first factor was nutrition with macro and micro element on two levels and second factor was four oat genotypes included V1, V2, V3 and V4. Results shows that the highest SPAD and photosynthesis speed was obtained from V4 genotype. Although the different between V4 and V3 was not significant. Also concomitant use of macro and micro fertilizers and improved growing conditions and better nutrition and providing the elements needed to build chlorophyll Causes achieve the highest levels of chlorophyll concentration and Also with providing the necessary elements for photosynthesis achieves the highest rate of photosynthesis is the treatment.
