Biological effects of cyanides on growth dynamics of corn and wheat plants

Abstract

The aim of this paper is to evaluate the effects of cyanides on cornand wheatplant growth. Seeds ofcorn (Zea mais) and wheat (Triticum aestivum) were put into Petri dishes on double filter paper together with solutions of cyanidesof different concentrations.The dynamicsof germination and root growth have been monitored. After that,the germinated seedswere planted in soil where they continued to growth. Two weeks later the content of photosynthetic pigments has been obtained spectrophotometrically.The negative effect frompoint of view of plant germination has been establishedforthese cyanides, these effects depending on concentration ofcyanide solutions. However,the content of some photosynthetic pigments increased, as a response of plantsto the chemical stress.
