Artemesia vulgaris when diluted to 100 mI. inhibited alfalfa seedling growth over 50%. The inhibitor was found in green and in dry plant material and could be extracted from either leaves, roots, stems, or flowers. It was stable to autoclaving at 20 p.s.i. for 20 minutes, but was destroyed completely when ashed. It was dialyzable and nonvolatile. It was soluable in polar and semipolar solvents and partly soluable in some nonpolar solvents. Inhibition e:~tracted with nonpolar solvents could be removed by shaking with water in a separatory funnel. The substance was not absorbed to either strong cation or anion exchange resins. Paper chromotographs run in isopropanol and water (90 - 10 /) in an IIIIIIIIOniatmosphere showed the inhibitor or inhibitors to have an Rf value between 56 and 76. Literature cited Bonner, J. 1950.
