Infection of Wheat by Loose Smut, Ustilago tritici (Pers.) Rostr.

Abstract

THE life-history of this disease was first investigated at the beginning of this century1, and it has been generally accepted that infection takes place through the stigmas at flowering time. A few workers2 considered, however, that the fungus may also penetrate directly through the ovary wall. In 19343 this latter phenomenon was actually reported, and in 1942 4 infection both down the style and through the ovary wall was said to occur. Very little appears to have been published on the path of the fungus from the inside of the ovary wall to infection of the embryo proper since it was first described by Lang1.
