Book excerpt: Excerpt from Blister Canker of Apple Trees, a Physiological and Chemical Study: A Dissertation Submitted to the Faculty of the Ogden Graduate School of Science in Candidacy for the Degree of Doctor of Philosophy, Department of Botany It is now generally recognized that among the most important problems of plant pathology are those connected with the physiol ogy of diseases whose etiology is already known. It is also recog nized that this must be the physiology of the host, of the parasite, and of the two in relation to each other, and, further, that such a comprehensive View of all the factors involved furnishes the only rational approach to an understanding of the principles underlying immunity and disease resistance. In the present paper are given the results of a physiological study of the destructive disease known as Illinois or blister canker, the etiology of which, including the identity of the causal organism, Nummularia discreta (schw.) Tul., was worked out by hassel bring (22) in 1902. The work reported here is a continuation of an earlier investigation by the writer (30) on the oxidase activity of healthy and diseased bark; in addition there is included an account of the catalase activity and microchemical and macro chemical analyses of both kinds of tissues. Further work is planned on the chemistry of the disease, on the role of other enzymes than. Oxidases, and on the physiology of the fungus itself in pure culture.
