التأثير المضاد لنبات الفلزلز ).L muticus Hyoscyamus)

Abstract

This study was conducted in the laboratory at Botany Department, Faculty of Arts and Sciences Tocra, University of Benghazi to investigate the effect of Allelopathy of aqueous extracts of leaves, flower and fruits of Hyoscyamus muticus L. Rich at concentrations of 0.5, 5, and 50% on seed germination and seedling development of Radish (Raphanus sativus L.). The results showed a difference in the Allelopathic effects on seed germination and development of seedling, indicating that extracts of leaves, flowers and fruits have an effect on reducing the percentage of germination and growth of the radical, especially at the concentration of 50% where germination was very low and sometimes completely inhabited. At 5% concentration the effect was moderate while at 0.5% the effect was positive. The results also showed that the leaves extract had a higher effect compared to the effect of flowers and fruits extracts
