 Title    Change of Chloroplast Ultrastructure in Radish Seedlings under the Influence of the Photosystem II-Herbicide Bentazon  
 Abstract    The influence of the photosystem II-herbicide bentazon on the ultrastructure o f chloroplasts o f radish seedlings (Raphanus sativus L.) was investigated with special emphasis on thylakoid developm ent and grana formation. Bentazon application (10-3 m) induces the formation of broader and higher grana stacks (grana width: 0 .5 -0 .6 n m ; greatest frequency: 3 -8 thylakoids per granum) than in the control plants (grana width: 0.3 |im; greatest frequency: 2 -4 thylakoids per granum). Furtherm ore, the am ount of chloroplast lamellae is enhanced, as are the stacking degree of thylakoids and the grana area. The chloroplasts of bentazon-treated plants appear to be shorter and thicker than in the controls and show all signs of a shade-type adaptation of the photosynthetic apparatus.
