sprouting Buds (turions) for fluridone treatments.

Abstract: This investigation was conducted to study the response of curly ponweed plants which grown from the different sprouting buds (Turions) for Fluridone herbicide at different concentrations (0, 0.1, 0.5,and 1.0 ppm).Results indicated that fluridone significantly reduced plant weight. The reduction in plant weight depended on the turion type. Dry weight of the plants erected from apical turion was the greatest value of others (lateral-apical and lateral turions). Also plants number and shoot length were decreased by increasing fluridone concentrations as compared with control. These results showed the importance of turion types used in growth. They also contribute to our understanding of the role of biological factors in regulating aquatic plant response to herbicide treatment. The best treatments were : exposing seedlings of pondweed grown from lateral or lateral-apical turions for fluridone at 0.5 and 1.0 ppm or the plants grown from apical turions for 1.0 ppm of the herbicide.. Therefore, the lateral and lateral- apical turions were susceptible more than the apical turions.
