Resumo: The application of cellulosic waste in forest plantations is an alternative to disposal, but more studies are necessary to confirm the safity of this disposal. The response of Pinus taeda L. to salinity in Humic Distrocryept was evaluated. In plantation, the seedlings were assessed for their height and stem diameter (SD), and at 120 days, were assessed the SD, height, dried root biomass (DRB), shoot (DBS) and total dried matter (TDM). The contents of P, K, Ca, Mg and Na were determinated, and, based on these levels it was estimated the quantity of these elements and calculated the efficiency use in leaves and roots and translocation to the shoot. Except the relationship between DSB/DRB, the other variables were significantly influenced by increased salinity with different effects among them. While the SD and its increase and DSP were reduced only in treatment at the more high electric conductivity (EC), the height of the seedlings and the increment tended to reduce from EC of 3.28 dS m-1 and DRB and TDM from the EC 0.55 dS m-1. The efficiency of P and Mg utilization decreased while K and Ca did not alter. The translocation of nutrients was not altered. doi: 10.4336/2010.pfb.30.61.51

Avaliou-se a resposta de Pinus taeda L. à salinidade, em NEOSSOLO LITÓLICO Húmico. No plantio, avaliaram-se a altura e diâmetro do caule (DC) das mudas e, aos 120 dias de cultivo, avaliaram-se a altura, o DC, a biomassa seca das raízes (MSR), parte aérea (MSPA) e total (MST). Baseados nos teores de P, K, Ca, Mg e Na, estimaram-se as suas quantidades acumuladas e suas eficiências de utilização nas acículas e raízes e a translocação para a parte aérea. Exceto a razão da relação MSPA/MSR, as demais variáveis foram influenciadas pelo aumento da salinidade, com efeitos diferenciados entre as mesmas. Enquanto o DC e o seu incremento e a MSPA foram reduzidas apenas no tratamento com a maior condutividade elétrica (CE), a altura e o seu incremento apresentaram tendência de redução a partir da CE 3,28 dS m-1 e a MSR e a MST a partir da CE 0,55 dS m-1. A eficiência de utilização do P e do Mg diminuíram, enquanto a do K e do Ca não foram alteradas. A translocação dos nutrientes não foi alterada. doi: 10.4336/2010.pfb.30.61.51Embrapa Florestas2010-06-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/11010.4336/2010.pfb.30.61.51Pesquisa Florestal Brasileira; v. 30 n. 61 (2010): jan./mar.; 51Pesquisa Florestal Brasileira; Vol. 30 No. 61 (2010): jan./mar.; 511983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/110/107Copyright (c) 2010 Shizuo Maeda, Helton Damin da Silva, Antonio Francisco Jurado Bellotehttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessMaeda, ShizuoSilva, Helton Damin daBellote, Antonio Francisco Jurado2017-04-28T13:14:29Zoai:pfb.cnpf.embrapa.br/pfb:article/110Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T13:14:29Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
