Phytotoxic Potential of Trans-chalcone on Crop Plants and Model Species
Journal of Plant Growth Regulation, 2013 Chalcones are flavonoid precursors that recently have been found to disrupt mitochondrial function and induce apoptosis in Arabidopsis radicles. However, whether they are potentially useful for weed control as selective herbicides depends on whether they are phytotoxic for important weeds and are not toxic for crops.
