Abstract Nomogram of germination of winter barley ( Hordeum vulgare L.) between dough stage and harvest, as influenced by temperature and rainfall Winter barley, cv. Katja , was cultivated on loess soil near Göttingen in three seasons (1982–1984). After passing the dough stage, barley seeds were separated at regular intervals and incubated at 12 °C for germination. For the germination (Y, in probits), the following regression equation was found: Y = 3.91 + 0.1186 X 1 – 0.0267 x 2 , where x 1 = daily mean temperature (°C), and x 2 = quantity of rainfall (mm) in the four days before the separation of the seeds. The relationship among germination, temperature and rainfall was presented in the form of a nomogram which shows a convenient method to solve the regression equation graphically.
