Resumo
The effect of scarification with sodium hypochloride on light sensitivity in seeds of Lactuca sativa L. cv. Grand Rapids is presented in the paper. Light-requiring lettuce seeds germinated in both dark and continuous light after scarification and 36 degrees C pre-incubation restored light sensitivity at 25 degrees C. Curves of dose-response indicated that chemical scarification induced a change in the control of seed germination from Low Fluence Response to the Very Low Fluence Response. Pre-incubation at 36 degrees C return the control to the Low Fluence Response of phytochrome action.
