Inhibition of seed germination under water extracts of sorghum (Sorghum bicolor L.) and its ratoon cultivated in swamp land
Main Article Content
Abstract
The results showed that the highest inhibition was found in the root of the main plant and the stem of the ratoon plant, where the normal growth was 6.00% and 22.00%, plumule length 3.29 cm and 3.57 cm, radicle length 0.84 cm and 2.58 cm, plumule wet weight 0.033 g and 0.030 g, radicle wet weight 0.003 g and 0.008 g), sprouts wet weight 0.075 g and 0.075 g, plumule dry weight 0.0033 g and 0.0030 g, radicle dry weight 0.003 g and 0.008 g, respectively. Likewise, those the same plant parts had cotyledon dry weight of 0.0185 g and 0.0168 g, ungrowth seeds 48.00% and 47, 00%, cotyledon wet weight 0.043 g and 0.038 g, as well as abnormal sprouts 46.00% and 31.00%, respectively. These findings indicate that the roots of sorghum main plant and its stems cultivated in swamp land become the best source of bioherbicides.
