The influence of light on the germination of potato seeds

A. Listowski, K. Rykaczewska


The influence of white and coloured Light and of the darkness on the germination of potato seeds was investigated. Potato seeds germinate in light as well as in darkness. Bed light is stimulative. Far-red and blue light depending of the origin of the seeds populations acted or inhibitive or only as a delaying factor. The after effect of R after FR or FR after R was also studied. The R-FR or FR-R photoreaction observed by potato seeds, differ from the classic pattern established by lettuce and tomato seeds.
