Resumo: This study was conducted to observe the combined effect of light and temperature on the flowering stage of sugar beet (Beta vulgaris L.) and to determine the minimum conditions of phototermal induction for several cultivars. Seed from twenty sugar beet cultivars were sown in pots containing sterilized soil and placed in growth chamber. During three weeks the pots were kept at 22°C degree of temperature under incandescent light (pre-induction period). After that, four plants of each cultivar were selected and submitted to cold treatment of 8.5°C with incandescent light for ten weeks. At the end of this period these plants continued to receive the same light treatment, but the temperature was increased to 25°C until the seed formation (post-induction treatment). From these results we concluded that through the phototermal induction is possible to verify the emition of seedstalks and flowering of sugar beet plants. Also it is possible to detect the requirements of light and temperature of different cultivars at the flowering stage.

Sementes provenientes de 20 cultivares de beterraba açucareira foram semeadas em vasos, contendo terra esterilizada, e colocadas em câmara de crescimento. Durante três semanas, os vasos permaneceram em ambiente com temperatura de 22°C e sob luz incandescente (período de pré-indução). Após, selecionaram-se quatro plantas de cada cultivar, e procedeu-se a tratamento de frio, com temperatura de 8,5°C, durante dez semanas, com luz incandescente contínua (tratamento de indução), e, posteriormente, essas plantas permaneceram com luz contínua e temperatura de 25°C até a formação das sementes (tratamento de pós-indução). Os resultados permitiram concluir que, através da indução fototermal, é possível verificar a emissão de haste floral e florescimento de plantas de beterraba açucareira, e verificar quais as exigências de luz e temperatura de diferentes cultivares ao florescimento.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPorto, Marilda PereiraFernandez, DanielSobral, Lúcia Salengue2013-09-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/17576Pesquisa Agropecuaria Brasileira; v.22, n.6, jun. 1987; 575-577Pesquisa Agropecuária Brasileira; v.22, n.6, jun. 1987; 575-5771678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/17576/11801info:eu-repo/semantics/openAccess2014-10-06T18:11:41Zoai:ojs.seer.sct.embrapa.br:article/17576Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-06T18:11:41Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
