Resumo: | In this experiment, the effect of different nitrogenous substances on the mycelium growth, sporulation and morphological aspects of the colonies of the fungus Colletotrichum gossypii South Var. cephalosporoides Costa planted in a solid substrate were observed. A synthetic substrate was used as a basic medium, and to this was added peptone metionine, asparagine, sodium nitrate or ammonium salicylate, according to the treatment. The control (group) received no nitrogen whatsover. It was concluded that peptone was the best treatment for sporulation and mycelium growth, and that the next best was asparagine which was helpfull in inducing sporulation. Ammonium salicylate inhibited the vegetative growth and the sporulation of the fungus. For the production of inocule, over a short period of time, the use of peptone as source of nitrogen is recommended. Differences in the pigmentation, edges, and density of the colonies were observed. Sporulation, though abundant in the substrate containing peptone and asparagine, ocurred in the form of localized masses of conidia in the first and as dispersed conidia in the second. |

Nesse trabalho procurou-se observar o efeito de diversas substâncias nitrogenadas sobre o crescimento miceliano, esporulação e aspectos morfológicos das colônias do fungo Colletotrichum gossypii South. var. cephalosporoides Costa em substrato sólido. Usou-se um substrato sintético como meio-básico e a este se adicionou peptona, metionina, asparagina, nitrato de sódio ou salicilato de amônia, conforme o tratamento. A testemunha não recebeu qualquer fonte de nitrogênio. Concluiu-se que a peptona foi o melhor tratamento para esporulação e crescimento miceliano, seguindo-se a asparagina que foi eficiente na indução da esporulação. O salicilato de amônia exerceu efeito inibidor do crescimento vegetativo e da esporulação do fungo. Para produção de inóculo, a curto prazo, recomenda-se o uso da peptona como fonte de nitrogênio. Foram observadas diferenças na pigmentação, bordos e densidade das colônias. A esporulação, embora abundante em substratos contendo peptona e asparagina, ocorreu em forma de verdadeiras massas localizadas de conídios na primeira, e como conídios dispersos na segunda.Escola de Agronomia - Universidade Federal de Goiás2007-10-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/2150Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 4, n. 1, Jan./Dec. 1974; 1-12Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 4, n. 1, jan./dez. 1974; 1-12Pesquisa Agropecuária Tropical; v. 4, n. 1, jan./dez. 1974; 1-121983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/2150/2090Carvalho, Yvo deCarvalho, Carluce Gomes de Sá einfo:eu-repo/semantics/openAccess2020-02-26T23:47:36Zoai:ojs.revistas.ufg.br:article/2150Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:54:56.281744Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
