Resumo: | This experiment was carried out to describe visual symptoms of macronutrients deficiencies in Stevia rebaudiana, and the effects of these deficiencies on growth, chemical composition and stevioside production. The symptoms were: yellowing with -N; dark green leaves with -P; clorotic, mottled, and necrotic leaves, with -K; apical necrosis, with -Ca; leaves with clorosis and necrosis in inverted "V" shape, with -Mg, and small pale green leaves, with -S. N, K, and Mg deficiencies reduced the leaf growth, therefore the plant marketable part. Mg deficiency caused greater reduction on the development of the radicular system. N, P, K, and S deficiencies decreasead the shoot:root dry weigth ratio, while Mg deficiency increased it. All deficiencies decreased the absorption of macronutrients, except of Ca, which reduced only the absorption of Ca, and K, that did not affect the absorption of Mg and S. The chemical content of the last five fully expanded leaf pairs showed good correlation with the plant nutritional status. The deficiencies of K, Ca, and S decreased the concentration of stevioside while all deficiencies, except of P, decreased the stevioside content. |

Os sintomas foram: clorose generalizada, com -N; folhas verde-escuras, com -P; folhas com clorose, bronzeamento e necrose, com -K; necrose de ápices, com -Ca; clorose e necrose foliar, em "V" invertido, com -Mg e folhas verde-pálidas e menores, com -S. As deficiências de N, K e Mg reduziram o crescimento das folhas e a parte comercializável da planta, enquanto que a deficiência de Mg promoveu acentuada redução no desenvolvimento do sistema radicular. As deficiências de N, P, K e S diminuíram a relação entre matéria seca da parte aérea e das raízes, enquanto a deficiência de Mg aumentou-a. Todas as deficiências causaram a diminuição na absorção de macronutrientes, exceto a de Ca, que reduziu somente a absorção de Ca, e a de K, que não alterou as absorções de Mg e S. A composição química dos cinco últimos pares de folhas totalmente expandidas representou bem o estado nutricional da planta. As deficiências de K, Ca e S reduziram somente o teor de esteviosídeo, enquanto todas as deficiências, exceto a de P, diminuíram o conteúdo de esteviosídeo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraUtumi, Marley MaricoMonnerat, Pedro HenriquePereira, Paulo Roberto GomesFontes, Paulo Cézar RezendeGodinho, Vicente de Paulo Campos1999-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5285Pesquisa Agropecuaria Brasileira; v.34, n.6, jun. 1999; 1039-1043Pesquisa Agropecuária Brasileira; v.34, n.6, jun. 1999; 1039-10431678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5285/2477info:eu-repo/semantics/openAccess2010-07-12T12:05:35Zoai:ojs.seer.sct.embrapa.br:article/5285Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-12T12:05:35Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
