Description :
Heavy metals are one of the important factors that have negative impact on man and environment, and their release to environment cause toxicity to plants that are continually exposed to potentially toxic heavy metals. Nickel is an essential nutrient for plants when it is in small quantity. Present investigation was executed with an objective to study the role of nickel chloride on chlorophyll content in Cicer arietinum(L), Vigna unguiculata (L), Pisum sativum (L) and Glycine max (L.) at different concentrations. The response of higher amount of NiCl to these parameters was found toxic as this concentration exceeds the micronutrient values of NiCl which are beyond permissible amount. Different NiCl levels remark by affected physiological growth of the plants. The toxicity of nickel affected the process of photosynthesis by damaging ultra- structure of chloroplast, less synthesis of chlorophyll.
