Indirect organogenesis from leaf explants of Eucalyptus benthamii x Eucalyptus dunnii and shoot multiplication
Background In Brazil, especially in the Southern region, stresses caused by cold and eventual frost are those that exert the most negative effect on the productivity of Eucalyptus spp. The genetic transformation techniques may contribute to forestry improvement programs in order to obtain genotypes expressing new interesting characteristics. They allow shortening the long breeding cycles and av...
متن کاملGrowth 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 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 ...
متن کاملFuel Properties and Suitability of Eucalyptus Benthamii and Eucalyptus Macarthurii for Torrefied Wood and Pellets
Torrefaction is the process of heating a material in the absence of oxygen, a pretreatment that represents a promising option for biofuels. Two eucalyptus species harvested in South Carolina, E. benthamii and E. macarthurii, were processed in a torrefier, and wood pellets were manufactured. Eucalyptus represents a promising biomass source in southern U.S. due to fast growth rates and the availa...
