The objective of this study was to reduce the consumption of Chromated Copper Arsenate type C (CCA-C) without affecting the quality of the treatment by determining the most efficient wood moisture interval for two genotypes of Eucalyptus sp. at different concentrations of active ingredients. A total of 54 fence posts of the species E. cloeziana and the hybrid E. camaldulensis x E. urophylla were treated. The pieces were randomly selected from three drying piles with different storage times in the yard (long, intermediate, and short). The active ingredient concentrations tested were 1.2, 1.4, and 1.6%. Retention analysis was performed to evaluate the quality of the preservative treatment. For both analyzed materials, the lowest and highest average retention values were observed in short and long storage piles and concentrations of 1.2% and 1.6% A.I. CCA-C, respectively. For E. cloeziana , only posts with a long storage time and treated with 1.6% of CCA-C were considered suitable for use in contact with the soil, according to the Brazilian standard, while for the clonal hybrid, posts with intermediate and long storage times, treated with 1.6% of CCA-C were considered suitable for use in contact with the soil. It was observed that CCA-C retention in the studied fence posts was directly influenced by the concentration of active ingredient in the preservative solution and by the storage time of the materials in the yard.","PeriodicalId":54443,"journal":{"name":"Scientia Forestalis","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2022-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86877446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If the species does not show considerable phenotypic plasticity, its distribution limits will be reduced. However, given the predictions of climate change, environments may undergo relatively abrupt variations and species will have to respond quickly to new conditions. To investigate how this can influence the dynamics of carbon compounds in plant tissues, studies on environmental gradients, combined with seasonal analysis of climate, are a powerful tool. The objective of this study was to evaluate the seasonal variation (dry period-rainy period) in the concentrations of non-structural carbohydrates and cell wall polymers in stems, branches and leaves of tree species distributed in zones of a restinga (sandbank) forest. For this, we carried out collections in the dry season (winter) and in the rainy season (summer) in populations of Eugenia bahiensis , Guarea macrophylla and Calophyllum brasiliense . Starch and hemicellulose concentrations were lower in the rainy season. However, the reduction in hemicellulose concentrations was the most uniform result. Probably, these molecules were used as energy source in the reproductive and growth demands of the species. Due to a long period of drought, the other non-structural carbohydrates (glucose, fructose and sucrose) did not show significant variations. Small variations in cellulose and lignin contents were attributed to fluctuations in the concentration of other molecules. In general, it was assumed that the low rainfall recorded during the study interfered with the expected seasonal responses. This phenomenon may have reduced the differences in soil moisture between forest zones.","PeriodicalId":54443,"journal":{"name":"Scientia Forestalis","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82906625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
