Photosynthetic Responses of Eucalyptus nitens Maiden at Initial Stages of Root-Rot Infection

Photosynthetic 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...

Floral 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...

Acoustic Wave Velocity as a Selection Trait in Eucalyptus nitens

Previous studies in Eucalyptus nitens have revealed favourable genetic correlations exist between acoustic wave velocity (AWV) in standing trees and modulus of elasticity (MOE), which can determine the suitability of trees for structural timber and/or engineered wood products. This study investigates the strength and stability of genetic variation in standing tree AWV across a range of environm...

Wound 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...
