Resumo: The characterization of shade effects on the physiology of coffee is important to determine optimum levels of radiation and temperature, as well as to subsidize studies on growth of shaded plants aiming at determining the ideal coffee plant architecture that maximizes the capture of the available solar radiation in shaded environments. The objective of this work was to evaluate physiological and growth characteristics of coffee (Coffea arabica L.) shaded with pigeonpea (Cajanus cajan (L.) Millsp.) and under full sun. The low level of incident radiation on the coffee shaded with pigeonpea caused decreases in the photosynthetic rate and transpiration, increased plant height and leaf size, but diminished leaf dry matter. These results indicate that the excess of shade drastically affects the physiology and morphology of C. arabica.

O objetivo deste trabalho foi avaliar características fisiológicas e de crescimento de cafeeiros (Coffea arabica L.) cultivados sob sombreamento denso com guandu (Cajanus cajan (L.) Millsp.) e a pleno sol. O baixo nível de radiação incidente sobre os cafeeiros sombreados com guandu resultou em decréscimos na taxa fotossintética e na transpiração, maior altura de planta, folhas maiores e com menor quantidade de matéria seca. Esses resultados indicam que o excesso de sombra afeta drasticamente a fisiologia e morfologia de C. arabica.–Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMorais, HeverlyMarur, Celso JamilCaramori, Paulo HenriqueRibeiro, Ana Maria de ArrudaGomes, José Carlos2003-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6682Pesquisa Agropecuaria Brasileira; v.38, n.10, out. 2003; 1131-1137Pesquisa Agropecuária Brasileira; v.38, n.10, out. 2003; 1131-11371678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6682/3739info:eu-repo/semantics/openAccess2014-08-11T19:32:40Zoai:ojs.seer.sct.embrapa.br:article/6682Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-11T19:32:40Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
