Abstract

We studied the influence of leaf extracts and leaf leachates of Lantana camara weed on the germination and metabolism of another weed Mimosa pudica. The extracts and leachates reduced the germination, speed of germination, seed viability and seedling emergence capacity of Mimosa seeds. The insoluble carbohydrate, protein, DNA and RNA and activities of dehydrogenase, catalase, peroxidase enzymes contents were significantly reduced. While, Amino acid, soluble carbohydrate levels (in seed leachates and seed kernels) and activity of amylase enzyme was increased in seeds pretreated with leaf extracts and leaf leachates.
