Growth 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 کاملEffects of the Interception of Litterfall by the Understory on Carbon Cycling in Eucalyptus Plantations of South China
For the purposes of forest restoration, carbon (C) fixation, and economic improvement, eucalyptus (Eucalyptus urophylla) has been widely planted in South China. The understory of eucalyptus plantations is often occupied by a dense community of the fern Dicranopteris dichotoma, which intercepts tree canopy leaf litter before it reaches the ground. To understand the effects of this interception o...
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 کاملLitter Production Dynamic in relation to Climatic Factors in Tree Plantations
We studied litterfall dynamic of tree plantations in Dez River floodplain, at 14 to 15 years old. The plantations consist of Populus euphratica Oliv., Eucalyptus camaldulensis Dehnh., E. microtheca F. Muell, Acacia farnesiana (L.) Willd., A. salicina Lindl., A. saligna (Labill.) H. Wendl., A. stenophylla Benth. and Dalbergia sissoo Roxb. Litterfall was different between the tree species, and le...
متن کاملIndirect 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...
