Abstract

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.
