Resumo: Variations in growth, total soluble sugars, mono and polyphenols, proteins and ribonucleic acids were studied in root tips of tomato (Lycopersicon esculentum Mill. cv. Campbell 33) submitted to boron deficiency for 0, 2, 4, and 6 days. From the second day onwards, boron deficiency reduced growth of the plants and also the concentration of total soluble sugars (a fact probably associated with the increased synthesis of structural material) and monophenols (a phenomenon associated to the increased oxidation of these compounds). Polyphenols, proteins and RNA were increased in the boron-deficient root tips. Boron may act more directly on the ribonucleic acid metabolism than on protein metabolism.

Campbell 33), submetido à deficiência de boro por 0, 2, 4 e 6 dias. A partir do segundo dia, a deficiência de boro reduziu o crescimento das plantas, os teores de açúcares solúveis (fato provavelmente associado à maior síntese de material estrutural) e de monofenóis (associado à maior oxidação desses compostos). Polifenóis, proteínas e ARN sofreram aumentos nas raízes deficientes. Possivelmente o boro tem ação mais direta sobre o metabolismo de ácidos ribonucléicos que de proteínas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMachado, Marcos A.Gomes, Maria Mercês de S.2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15162Pesquisa Agropecuaria Brasileira; v.18, n.2, fev. 1983; 105-109Pesquisa Agropecuária Brasileira; v.18, n.2, fev. 1983; 105-1091678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15162/8954info:eu-repo/semantics/openAccess2014-04-16T18:50:35Zoai:ojs.seer.sct.embrapa.br:article/15162Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T18:50:35Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
