ALLELOPATHIC EFFECTS OF AQUEOUS EXTRACT OF LEAVES OF ABUTILON INDICUM (L.) SWEET AND PARTHENIUM HYSTEROPHORUS L. ON SEED GERMINATION AND SEEDLING GROWTH OF BARLEY

Abstract

Allelopathic effect of 3% aqueous extracts of fresh leaves of Abutilon indicum (L.) Sweet and Parthenium hysterophorus L. were studied on seed germination and seedling growth of barley (Hordeum vulgare L. local var. RD 2035). Seeds were allowed to grow in petri-dishes contains 3% leaf extracts of A. indicum and P. hysterophorus. The result indicated that seedling growth was promoted by A. indicum while suppressed by P. hysterophorus. Seed germination was not affected by A. indicum whereas inhibited by P. hysterophorus.
