Accumulation of Cu at different concentration of tea plant (camellia saneness (L.) O. Kountze)

Abstract

Tea is the most popular beverage in the world. Tea is considered a beneficial drink as it contains many essential nutrients. But the intake of heavy metals even in a small amount causes adverse action in human health along with the plants. The heavy metals are present in the nutrient media itself which are required for plant growth, other important sources are pesticides and fertilizers used in the field for better production. In the present study the tea cultivars (S3A3) were collected from the Rosekandy tea estate, Silchar, Assam and were analyzed for the accumulation of Cu at different level on the different organs of the plants. The accumulation of Cu had a strong positive correlation with the Cu concentration. The order of deposition of Cu are in following manner roots>leaves>stems with the exposure of treatment days. From the present study we have concluded that even low amount of deposition of Cu at higher concentration causes adverse affect by retarding the growth of a plant with many other physiological characters. And this may lead to the adverse action of biological characters.
