• Lettuce seeds were soaked in a ^3H-thymidine solution and autoradiogram of sections of these seeds, fixed prior to and after germination (root protrusion), were prepared. Labeled nuclei in intact, punctured, as well as broken seeds began to appear approximately at the time of root protrusion. In the nuclei of the radicle, the beginning of ^3H-thymidine incorporation precedes the division of nuclei by one to two hours, and all the dividing cells incorporate ^3H-thymidine before their first division. Occasional dividing cells in the epidermis of the hypocotyl were not found to be ^3H-labeled. In intact seeds, the nuclei observed in the cone of the plumule showed radioactivity approximately 3-4 hr after germination, while in punctured and broken seeds the ^3H-incorporation occurred some hours earlier.
