Resumo: The effect of water stress on the regulation of gas exchange and on the accumulation of abscisic acid (ABA) in the leaves of different cultivars of Vitis vinifera L. has been analysed with the purposes of characterizing the varietal behavior and of identifying a marker for the different forms of response. Two-year old plants grafted on 'Fercal', planted in plastic pots and cultivated under controlled conditions were used. Long period of water stress (20 days) revealed two groups of cultivars with different sensitivities at the gas exchange level. The ABA content of the leaves was related to the functioning of the stomata, showing that the most sensitive cultivars presented the lowest contents of ABA in the test plants, whereas the greatest accumulations of this hormone occurred in the stressed plants.

Foram utilizadas plantas de dois anos, enxertadas sobre 'Fercal', plantadas em vasos de plástico e cultivadas sob condições controladas. A aplicação de um estresse hídrico de longa duração (20 dias) revelou dois grupos de cultivares com diferentes sensibilidades ao nível das trocas gasosas. Os teores de ABA das folhas estiveram associados ao funcionamento dos estômatos, mostrando que as cultivares mais sensíveis apresentam os menores teores de ABA nas plantas-testemunha, e os maiores acúmulos deste hormônio nas plantas estressadas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária Brasileirade Albuquerque Regina, MurilloCarbonneau, Alain1997-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4689Pesquisa Agropecuaria Brasileira; v.32, n.6, jun. 1997; 579-584Pesquisa Agropecuária Brasileira; v.32, n.6, jun. 1997; 579-5841678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4689/7343info:eu-repo/semantics/openAccess2015-03-30T19:38:44Zoai:ojs.seer.sct.embrapa.br:article/4689Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-03-30T19:38:44Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
