We investigated changes in the pattern of water use of an 8-year-old Eucalyptus nitens (Deane and Maiden) Maiden plantation soon after thinning. Sap flow sensors using heat pulse technology were deployed across three stands thinned to a final density of 100, 250 or 600 trees ha-1 plus an unthinned control (1250 trees ha-1). Changes in the relationship between tree size and daily water use were ...

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...

Study of the dynamics and distribution of lepidopteran defoliators is important because some of them are major pests of eucalyptus. More than 3,000,000 ha of eucalyptus are now planted in Brazil even though the genus is not native there. The goal of this study was to document the frequency and constancy indexes of lepidopteran pests of Eucalyptus grandis Hill ex Maiden (Myrtaceae) collected wit...

India’s forest cover was estimated to be about 67.701 million hectares or 22.8 percent of the country’s land area and other wooded lands comprise of 4.11 million ha (UNEP Report, 2000). The dense forests in almost all the major states has been reduced and forest degradation is a matter of serious concern now. Principal plantation species such as Acacia spp., Eucalyptus spp. and Tectona grandis ...

In the subsequent 20 years as the garden’s director, Maiden seized every opportunity to improve the herbarium. Even internationally destructive events such as World War I provided unexpected additions: one soldier alone donated 300 specimens from Palestine. And a further parcel from Kew revealed 58 acacia and 23 eucalypt specimens collected between 1816 and 1839. Maiden was also occupied by sev...

Despite the growing importance of Eucalyptus wood as raw material for pulp and paper, there is a lack of knowledge on the chemistry of their macromolecular components. The present paper addresses this issue by applying the recently developed protocol for isolating enzymatic mild acidolysis lignins (EMAL) from Eucalyptus grandis, Eucalyptus globulus and the softwood species Douglas fir and white...
