Changes in Biochemical Variations of Sesuvium portulacastrum under Copper and Zinc Treatment

The present work deals with the ecophysiological studies on the biochemical contents of the effect of copper and zinc on Sesuvium portulacastrum L. The Sesuvium portulacastrum plant are grown in pots in a spilt plot design with copper and zinc concentration levels as main treatments (control, 100, 200, 300, 400, 500 and 600 mg/kg-1). The experiments were replicated five times. The Sesuvium portulacastrum plants are raised in pots. The copper and zinc were mixed with (1:2) the sand and applied to the pot soil (10 kg /acre). The two heavy metals copper and zinc were applied in the soil mixed. Pots were irrigated as and when necessary. The plant samples were analyzed at four different intervals (30, 60, 90 and 120th DAS). The results indicates that the heavy metals (copper and zinc) application, at the six rates (100, 200, 300, 400, 500 and 600 mg kg-1) caused reduction in various biochemical contents such as (Amino acid, Proline, Protein, Total sugar and Starch) when applied copper and zinc. Increasing in various bio chemical contents such as (Amino acid, Proline, Protein, Total Sugar and Starch) copper 200 mg kg-1, zinc 300 mg kg-1 only increased low concentration and higher concentration is decreased the all biochemical contents Sesuvium portulacastrum.
