Book excerpt: Excerpt from A Study of the Effect of Environmental Factors on the Variability of Physiologic Forms of Puccinia Graminis Tritici. Erikss. And Henn In dealing with the effect of environment on the development of stem rust, the only factor under absolute control was temperature. By varying temperature while other conditions remained relatively constant, it was possible to ascertain the part which that factor played in the development of the parasite on its host. Other external conditions, such as light, humidity and carbon-dioxide concentra tion, were under imperfect. Control, so that their relative importance can be stated with less accuracy.
