Growth stress in Eucalyptus dunnii
Growth stress in 9-y-old plantation-grown Eucalyptus dunnii was assessed by measuring longitudinal growth strain. Strain varied considerably (370–1560 μm–1) and was sufficiently heritable (h2 = 0.3–0.5) that tree breeding may be an effective way to reduce the incidence of growth stress in this species. Although the formation of longitudinal growth strain appears to be under strong genetic contr...
متن کاملTracking down worldwide Puccinia psidii dispersal
Background Puccinia psidii causes rust disease on many host species in the Myrtaceae [1]. First reported in 1884 on guava in Southern Brazil [2], the rust has since been detected on several myrtaceous in South America, Central America, Caribbean, Mexico, USA: in Florida, California, and Hawaii. More recently, P. psidii was reported in Japan infecting M. polymorpha[3]. Of special note is that a ...

متن کاملA preliminary assessment of high risk areas for Puccinia psidii (Eucalyptus rust) in the Neotropics and Australia
Puccinia psidii Winter, which causes both guava rust and eucalypt rust, is an important pathogen on eucalypts and other members of the Myrtaceae family in the Neotropics. If introduced into Australia it could represent a major potential threat to eucalypt plantations as well as native vegetation. Observations of the distribution of eucalypt rust epidemics in the Neotropics were analysed to deve...
متن کاملUse of SSR-Tools for clone certification in Uruguayan Eucalyptus grandis and Eucalyptus dunnii breeding programs
Background Over the last two decades, commercial plantations in Uruguay have increased exponentially, particularly those destined for pulp and paper industry. Although the about 700,000 ha of commercial plantations of Eucalyptus are a continuous source for the selection of elite genotypes, there is no national registration system for Eucalyptus clones in this country. The traditional procedure ...
