Lincoln, Jr. 2 " University of Massachusetta Agricultural Expedment Station Amherst, Massachusetts Introduction Donnalley and Ilahn (3) have reported that they applied Cl4 labeled amino triazole to the leaves of the Northern nutgrass plant. Autoradiograms of treated plants ahatTedthat the chemical was trans· , located in'the plant and into the tubera. Subsequeae'tests showed that this treatment reduced cermination of the tubers. The object of this experiment was to detemine whether foliar applications of amino triazole are translocated to the inflorescence and if this treatment has an affect on seed germiaatiOn. }~terials and 118thods Plants of Northern nut grass (~eru8 esculencu I ) were erown in the ereenhouse and treated with~4 labeled 3 am no-l,2,4 triazole; the tacced atom was on the S-position of the triazole ring. The specific activity of .this chemical waa 0.9S millicuries per millimole. A 4500 ppm stock solution, contaiatngSO microcuries, was prepared by.addinz distilled water to the sample. Each treatment consisted of a ten microliter droplet, with an activity of 0.5 microcurie., beins placed inside a: lanolin ring on the plant.~eactiv1ty was aimUar :lD all 1;&8e8,.but the site of appl1catioD and the duration of the treatment wa..... r:Led.
