Forest Ecology and Management | Year: 2013

Organized forestry in Brazil began in the late 1960s, stimulated by a government policy which subsidized afforestation programs from 1967 to 1989 to develop an internationally-competitive wood-based industry, managed by the private sector. Currently, planted forests in Brazil total about 6.9million ha, from which 4.9million ha is planted with eucalypt (around 25% of world plantation), 1.6million ha with pine, and 0.42Mha with other species. Roundwood consumption of forest plantations totaled 170.1millionm3 in 2011, eucalypt plantation accounted for 80.6% of this total.Most eucalypt plantations are managed in short rotations (6-8years) and are established in regions with water, nutritional and frost stresses of low to high degrees. The mean annual increment is 40m3ha-1year-1 roundwood, ranging from 25 to 60m3ha-1year-1 depending on the level of environmental stress. Improving natural resources use efficiency by breeding and matching genotypes to sites and using appropriate site management practices is a key challenge to sustain or increase productivity.The wide range of eucalypt species and hybrids with different climatic and edaphic suitability associated with the easy propagation by seeds and cloning allow the adaptation of plantations to various tropical and subtropical regions in Brazil. The possibility of using eucalypt wood in a range of purposes has led large and small enterprises to establish eucalypt forests for multiple uses. The desirable characteristics in association with the accumulated knowledge on eucalypt silviculture encourage the use of this genus in most plantations. The most important factors in the selective process for a genotype are wood characteristics, productivity level, susceptibility to pests and diseases, drought tolerance, especially in tropical regions (frost free), and frost tolerance in subtropical regions (mostly without water deficit). In regions with pronounced seasonality and moderate to long drought periods, the planting of hybrid genotypes predominates, propagated by cloning. Under subtropical conditions, the planting of single species predominates, propagated by seed. Clonal plantations with interspecific hybrids have been fundamental for eucalypt adaptation in regions under water and nutritional stresses. Given the rapid advances in eucalypt breeding, regarding adaptation to water stress and resistance to diseases and pests, and the adoption of clonal propagation techniques, genotypes are rapidly becoming obsolete and are replaced by more productive ones after harvesting. Thus, the replanting of crops has become a common procedure after the second half of the 1990s in Brazil.This paper describes the basic requirements for integrating genetic and silvicultural strategies to minimize abiotic and biotic constraints in eucalypt plantations. © 2013 Elsevier B.V.

The Maytenus ilicifolia Mart. ex Reissek (Celastraceae), traditionally known as “espinheira-santa” in Portuguese, is native and cultivated in South Brazil. Its leaves contain triterpenes and polyphenolic compounds (favonoids and tannins), which are related to the antiulcerogenic effect. The aim of this work was to evaluate the dried biomass production (g), height (m), ramifcation, and also the total content in polyphenol compounds of the leaves from the M. ilicifolia specie, which were developed under two different light conditions after two different pruning treatments. The design of the experiment was randomized blocks with two levels of light (shadow or full sunlight) and two levels of prune (partial and drastic), with four replications. The height of the plants grown in the shadow was greater for the treatment of drastic pruning than in plants in full sunlight. The ramification increased significantly with drastic prune in full sunlight. The plants grown in full sunlight showed a significant higher content in total polyphenols than the plants grown in the shadow, 10.29±0.20% (RSD=1.94%) and 7.16±0.09% (RSD=1.30%) respectively. © 2014, Instituto de Biociencias.

This study evaluated genetic parameters, heterogeneity of residual variances and genotype x environment interaction, comparing the results obtained by Blup and Blup-Het procedures in Pinus taeda L. progeny tests. Experiments were set in random blocks with 150 treatments. Three experiments were located in Santa Catarina state and two were set in Paraná state, Brazil, with 5 and 9 blocks per site, respectively, and six plants per plot. At 6 years old, the progenies were evaluated for height and diameter. In general, results demonstrated that high residual variance lead to variance heterogeneity. When variances are associated to high genetic correlations among height and diameter characters, they indicate that Blup-Het procedure should be used, even if they present similar results, because genetic parameters estimated based on individual heritability for progeny is more accurate. Genotype x environment interaction was low, given similarities among progeny variance and similarity components, selected by adaptability, stability and productivity criteria. The genetic improvement program may be conducted at one site, due to the environments similarities, as demonstrated by effects from genotype x environment interaction determination coefficient and genetic correlations across sites.

This paper aims to make an economic evaluation of the results already achieved through implementation of Advanced Process Control (APC) in the pulp and paper industries. For this, we firstly describe some basic concepts, and then some cases of practical applications that have reported good outcomes are cited. Companies have invested in this technology, and there are many applications already in operation. It is worth to discuss now, after the euphoria of the initial results, what effectively are the outcomes achieved over the past years and, also, how to keep them in full control capability, promoting the appropriate maintenance actions for the effects initially achieved be improved over its use.
