A significant increase in protein content of bean cotyledons resulted by applications of 0.5 ppm of atrazine (2‐chloro‐4‐ethylamino‐6‐isopropylamino‐ s ‐triazine), simazine [2‐chloro‐4,6‐bis(ethylamino)‐ s ‐triazine], terbutryn (2‐methylmercapto‐4‐ethylamino‐6‐isobutylamino‐.s‐triazine), or GS‐14254 (2‐methoxy‐4‐isopropylamino‐6‐butylamino‐ s ‐triazine) to the foliage of 5‐6 week old bean plants grown in a controlled environment or field conditions. Aen electron microscopic study indicated that in the cotyledonary cells s ‐triazines inducd a 2‐fold increase in the number of cisternae of rough endoplasmic reticulum. These treatments also increased the number of vesicles, which apparently contain protein, and the amount of cytoplasmic ribosomes.
