Abstract (2. Language): 
The aim of the study was to investigate heavy metal accumulation in wheat (Triticum aestivum) and oat (Avena sativa), and other physiological and biochemical parameters affected by these heavy metals. The data revealed that maximum plant fresh weight and plant dry weight was recorded for oat and minimum plant fresh weight and plant dry weight was noted for wheat (Triticum aestivum). The data also indicated that higher concentration of proline and DNA concentration was noted in wheat (Triticum aestivum) while lowest in oat (Avena sativa) plant. While DNA purity was highest in wheat (Triticum aestivum) and found lowest in oat (Avena sativa). Highest concentration of protein was recorded by wheat (Triticum aestivum) while lowest protein concentration was noted for oat (Avena sativa). The data further showed that wheat (Triticum aestivum) recorded maximum Cd concentration while minimum Cd concentration was noted in oat (Avena sativa). Highest concentration of Cr was noted in oat while minimum Cr concentration was recorded by wheat (Triticum aestivum). A maximum level of Pb was shown by oat (Avena sativa) while minimum levels of Pb were noted in wheat (Triticum aestivum). So oat (Avena sativa) plant is the higher accumulator of heavy metals i-e Cr and Pb while wheat (Triticum aestivum) accumulates Cd in highest concentrations.
