Abstract
the number of weeds at each plots were evaluated. L. muscari showed most practical weed suppression from second year to fifth year. L. muscari had strong allelopathic activity by bioassays. This Japanese domestic ground cover plant contained azetidine-2-carboxylic acid, a non-proteinogenic amino acid analogues to proline, at high concentration in root and leaves, and supposed to have a role as allelochemical to suppress weed on the field.
