Biotechnology's Potential Contribution to Global Wood Supply and Forest Conservation AgEcon
Sedjo, Roger A..
Over the past 30 years, industrial plantation forests have become a major supplier of industrial wood. There are several reasons for this, including the improved economics of planted forests due to biotechnological innovations, the increases in natural forest wood costs due to increasing inaccessibility, and rising wood costs from natural forests due to new environmental restrictions related to logging. Forestry today is on the threshold of the widespread introduction of biotechnology into its operational practices. In many cases, the biotechnology likely to be introduced is simply an extension of that being utilized in agriculture, such as herbicide-tolerant genes. However, biotechnology in forestry also is developing applications unique to forestry,...

Zanuncio,Antônio José Vinha; Carvalho,Amélia Guimarães; Carneiro,Angélica de Cassia Oliveira; Valenzuela,Paulina; Gacitúa,William; Leite,Fernando Palha; Colodette,Jorge Luiz.
Abstract: The objective of this work was to test a new methodology to assess the resistance of trees to wind damage and determine the characteristics that increase clone resistance to winds. Tree resistance to breakage, basic density, ultrastructure, anatomy, mechanical properties, and wood growth stress have been evaluated in seven Eucalyptus grandis × Eucalyptus urophylla clones, collected from a region with a high incidence of wind damage. The Pearson correlation coefficient between the tree resistance to breakage and the ratio between the area damaged by the winds and the total planted area was -0.839, showing the efficiency of the methodology adopted and that high breaking strength results in a smaller area affected by wind damage. Trees with a high...

Development and antioxidant capacity of sapota pulp Jelly (Quararibea cordata Vischer) Ciência e Agrotecnologia
Carvalho,Vania Silva; Damiani,Clarissa; Asquieri,Eduardo Ramirez; Orsi,Daniela Castilho; Nishi,Adriana Cândida Faustino.
Sapote (Quararibea cordata Vischer), also known as a chupa-chupa, is originated from the Brazilian, Peruvian and Colombian Amazon. The pulp of the ripe fruit is edible, fibrous, of intense orange color, sweet flavor and aromatic. Since the fruit is known in the Amazon only in its domesticated state, this work becomes necessary. With the aim of meeting the demand for new products in domestic and international markets, sapota pulp jelly has been developed. The jelly was assessed for moisture, ash, lipids, proteins, carbohydrates, dietary fiber, pectin, pH, total acidity, solids soluble, sugars, organic acids, carotenoids, phenolic compounds and antioxidant capacity. The final product met the standards required by Brazilian law, and 32.68% moisture and 61.06%...

Diversity and characterization of ramie-degumming strains Scientia Agricola
Duan,Shengwen; Liu,Zhengchu; Feng,Xiangyuan; Zheng,Ke; Cheng,Lifeng; Zheng,Xia.
Ramie (Boehmeria nivea and Boehmeria tenacissima) is a widely used fiber crop. Traditional water retting or chemical boiling method performed in order to extract ramie fiber seriously pollute the environment and severely damage the fiber, so biological method is the general trend of the fiber-extracting industry. Some strains (687), involving 26 genera and 43 species, were collected from the three samples, which produce hydrolyzed circles in the selective culture medium in order to detect the degumming effect and to compare the enzyme activity. Among these strains, 13 of them did not produce cellulase and had a ramie decreasing weight rate above 25 %, which were regarded as efficient ramie-degumming strains named from R1 to R13. R1 to R13 belonged to...
