Leaf water relations of Eucalyptus globulus ssp. globulus and E. nitens: seasonal, drought and species effects.
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...
متن کاملWound wood formation in Eucalyptus globulus and Eucalyptus nitens: anatomy and chemistry
The wound-associated wood that developed 17 months following artificial xylem injury in Eucalyptus globulus (Labill) and Eucalyptus nitens (Maiden) was examined anatomically and chemically. This new tissue located immediately adjacent to the wound site and termed “wound wood” was highly variable consisting of callus, altered wood of increased parenchyma density, and dark extractives, visible to...
متن کاملEucalyptus Globulus
"The authentic facts, relating to the remarkable power of the Eucalyptus Globulus in drjing marsh lands and rendering them healthy, are such as to deserve serious and general attention. It appears to be certain that where the Eucalyptus prospers intermittent fever disappears. This tree grows with incredible rapidity, absorbs ten times its own weight of water in twentyfour hours, and spreads thr...
متن کاملFloral induction in Eucalyptus nitens.
Eucalyptus nitens (Deane & Maiden) Maiden takes at least five years to initiate flower buds from seed and is an infrequent and light flowerer. Because this behavior constitutes a major impediment to breeding programs, we examined the mechanisms controlling floral induction in E. nitens, with the long-term aim of reducing generation time and increasing seed yield. Application of paclobutrazol re...
متن کاملPhotosynthetic temperature responses of Eucalyptus globulus an
temperature of 4-year-old Eucalyptus globulus Labill. and E. nitens (Deane and Maiden) Maiden trees were measured between 10 and 35 °C at approximately monthly intervals from early spring to midwinter. The photosynthetic temperature optimum of recently expanded leaves in the sun canopy was linearly related to the average temperature of the preceding week during the 9-month measurement period. T...
