Pathogenicity evaluation of Cytospora eucalypticola isolated from Eucalyptus spp. cankers in Uruguay
Cytospora eucalypticola has been frequently associated with twig and stem cankers and as endophyte of Eucalyptus globulus and E. grandis in Uruguay. Mycelium discs of two C. eucalypticola isolates obtained from actively growing colonies were inoculated, both superficially and on experimentally wounded stems of E. globulus and E. grandis. No inoculated and control plants have shown any discolora...
In August 1990, a 2-ha plantation was established in an area where rainfall (about 515 mm year(-1)) was insufficient to meet evaporative demand. On nine occasions between September 1991 and April 1993, pressure-volume curves were constructed for irrigated and rainfed Eucalyptus globulus ssp. globulus Labill. and E. nitens (Deane and Maiden) Maiden trees. During the experiment, rainfed trees exp...
The crown structure of Eucalyptus nitens (Deane & Maiden) Maiden 6 years after thinning, and the development of stand leaf area index both immediately and 6 years after thinning, were investigated. Thinning did not alter branch angle, branching density or the relationship between branch size and branch leaf area. However, larger branches were found in the lower crown of thinned trees and the in...
We examined the adjustment of leaf angle (L theta) and foliar chlorophyll and xanthophyll chemistry in Eucalyptus nitens (Deane and Maiden) Maiden seedlings maintained in various nitrogen (N)-supply treatments over a 6-month period. Adjustment of L theta toward the vertical was greatest under conditions of foliar N deficiency and became incrementally more horizontal with increasing foliar N con...
In silviculture, mineral fertilization is necessary to supply the nutritional demand, however, recommendation of quantities be applied should aim at maintaining productive capacity soil. The purpose this study test whether increasing recommended fertilizer dose improves soil fertility and increases productivity Eucalyptus dunnii in sites central region Pampa biome, Brazil. doses 150 g (T0), 225...
ABSTRACT A new species of the pseudoscorpion genus Cystowithius Harvey, 2004 is described based on several males and females collected in Cordillera Central near Manizales Villamaria, Caldas, Colombia. The type series was under or bark Eucalyptus grandis W. Hill ex Maiden (Myrtaceae). ankeri sp. nov. fifth genus, differing from its four congeners by characters, including position male sternal i...
