Dutch elm disease has been so devastating in Europe and some other parts of the northern hemisphere as to have transformed the landscape in the worst afflicted areas. This article reviews the nature and origin of the disease; the way in which it spre

Clonal propagation or apomixis is common in the plant kingdom. Among trees, agamospermy and vegetative propagation are relatively rare in nature. In this paper the roles of different modes of propa...

This paper contributes some data to the discussion about the decline of Ulmus in pollendiagrams from many parts of Europe at about 3000 B.C. It is shown that this decrease most probably was not caused by any known disease or pest of elm. Another expl

The localizing of pathogen (Ceratocystis ulmi) establishment in Dutch elm disease-resistant hosts is hypothesized as the major mechanism of resistance to this disease. Four factors are proposed that, singly or in all possible combinations, could regu

Some types of elm hybrids resistent to the Dutch elm disease turned out to be susceptible toNectria cinnabarina(Tode) Fr. This fungus may behave as a parasite, killing branches. Virulent and non-virulent strains are known. A method is described for c
