Resumo: | This work was conducted at the Coastal Research Department of the Ceará State Research Service at Maracanaú County, CE, Brazil. The objective was to study the phenology of herbaceus cotton cultivars Gossypium hirsutum L., r. latifolium Hutch. The following cultivars: IAC 17, IAC 19, IAC 20, CNPA Precoce 1, CNPA Acala 1, EPAMIG 3, EPAMIG 4 (MG 79 - 1506) and PR 380/82 were used. Four experiments were conducted: two under dryland conditions, one under dryland conditions and complementation with water, and one under irrigated conditions. The plot had four rows, 1 m apart, with 5 m long. The following parameters were observed: first flower-bud, first flower-bud with 6 mm in diameter, first flower, first hard boll, first open boll, first and last picking. The data showed that in a same cropping season the phenological events practically showed no difference. The phenological stages changed among cropping seasons probably due to water supply. The values of the four cropping seasons showed the first flower-bud with 26,63 days after plant emergence; first flower-bud with 6 mm with 32,45 days; first flower with 46,73 days; first hard boll with 68,95 days; first open boll with 95,00 days; first picking with 114-124 days; and last picking with 138-146 days. |

Foram conduzidos quatro experimentos: dois em regime de sequeiro; um, em regime de sequeiro com complementação de água, e um, em regime de irrigação, envolvendo as cultivares IAC 17, IAC 19, IAC 20, CNPA Precoce 1, CNPA Acala 1, EPAMIG 3, EPAMIG 4 (MG 79-1506)e PR 380/82. As parcelas constaram de quatro linhas com espaços, entre si, de 1 m, com 5 m de comprimento. As características computadas foram: aparecimento do primeiro botão floral, do primeiro botão floral com 6 mm de diâmetro, da primeira flor, da primeira maçã dura, do primeiro capulho, da primeira e última colheita. Foi observado que dentro de uma mesma safra os eventos fenológicos praticamente não apresentaram diferenças. Os estágios fenológicos tiveram seu aparecimento modificado nas diferentes safras, ocasionado, provavelmente, por diferentes condições de suprimentos de água. Os valores obtidos nas quatro safras estudadas foram: 26,63 DAE (dias após a emergência) para o aparecimento do primeiro botão floral; 32,45 DAE para o aparecimento do primeiro botão floral com 6 mm de diâmetro; 46,73 DAE para o aparecimento da primeira flor; 68,95 DAE para o aparecimento da primeira maçã dura; 95,00 para o aparecimento do primeiro capulho; 114 a 124 DAE para a primeira colheita e 138 a 146 para a última colheita.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBleicher, Ervinode Lima, Raimundo NonatoNeto, Francisco das Chagas Vidal1995-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4411Pesquisa Agropecuaria Brasileira; v.30, n.9, set. 1995; 1177-1182Pesquisa Agropecuária Brasileira; v.30, n.9, set. 1995; 1177-11821678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4411/1697info:eu-repo/semantics/openAccess2010-06-07T20:26:51Zoai:ojs.seer.sct.embrapa.br:article/4411Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-06-07T20:26:51Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
