Abstract
Environmental pollution due to industrial activity, mining, agricultural activity and transportation, leads to production of high amounts of contaminants like heavy metals into surface water and ground water and soils which ultimately leaches to ground water and also affects the biosphere. Seed is the developmental stage that leads to subsequent vegetative developmental processes Cucumis sativus L. and it becomes sensitive to external stress. In this study, germination was conducted in cucumber [Cucumis sativus L.] in order to find out the changes in germination, different developmental stages in terms of its growth, physiological and biochemical alteration due to nickel stress. The seeds of cucumber were germinated in variable nickel concentrations of ranging from 0-100 mg/L of Nickel as nickel chloride solution. It was found that germination percentage and Seedling vigour indices were reduced with increasing concentration of nickel. In another experiment conducted in pot culture revealed that, different physiological and biochemical parameters like total chlorophyll content and total protein content were decreased whereas free proline content were increased with increase in concentration of Nickel. It was also observed that seeds of cucumber showed better result in terms of different physiological and biochemical parameters in 20 ppm of Nickel at different interval of days like 10th, 20th and 30th days of growth of seedling thereby indicating that Nickel within 20 mg/kg could facilitate the plants growth and it is subsequently affect the seedling when it exceeds from 20 mg/kg of nickel in soil.
