Resumo: The plant response of the peanut (Arachis hypogaea L.) crop submitted to two different levels of irrigation was evaluated with the objective of determining the diurnal variation of the stomatal resistence of the BR-1 cultivar, and was related with the photon flux density of the photosynthetically active radiation. The experiment was conducted at the Experimental Station belonging to the Companhia de Desenvolvimento do Vale do São Francisco, situated in the municipality of Rodelas, BA, Brazil. The soil is classified as fine sandy soil. The experiment was conducted during the period of August to December 1994. The planting took place on the 6th of August, 1994. The amounts of irrigation applied were 300 mm and 700 mm, and the irrigations were applied at four-day intervals. The leaf stomatal resistences and the photon flux density of the photosynthetically active radiation were measured. Under non-stressed conditions, the peanut crop shows a hyperbolic relation between the stomatal resistence and photon flux density. The water stressed plants present the phenomenon of stomatal closure around midday.

O experimento foi conduzido, em condições de campo, na Estação Experimental da Companhia de Desenvolvimento do Vale do São Francisco, situada no município de Rodelas, BA, em solo de classificação textural areia fina, durante o período de agosto a dezembro de 1994. As lâminas aplicadas foram de 300 e 700 mm, com frequência de quatro dias por rega. Mediram-se as resistências estomáticas e a densidade de fluxo de fótons de radiação fotossinteticamente ativa sobre a superfície das folhas. Em condições de bom suprimento de água para as plantas, existe uma relação hiperbólica entre as resistências estomáticas e a densidade de fluxo de fótons. Em condições de deficiência hídrica, o amendoim apresenta o fenômeno de "fechamento do meio-dia".Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCarlos Silva, LuizFideles Filho, JoséEsberard de Macêdo Beltrão, NapoleãoVenkata Ramana Rao, Tantravahi1998-03-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4844Pesquisa Agropecuaria Brasileira; v.33, n.3, mar. 1998; 269-276Pesquisa Agropecuária Brasileira; v.33, n.3, mar. 1998; 269-2761678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4844/6966info:eu-repo/semantics/openAccess2014-11-19T16:54:22Zoai:ojs.seer.sct.embrapa.br:article/4844Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-11-19T16:54:22Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
