Resumo: | The objective of this work was to compare phyllochron and leaf area on individual stalks of selected sugarcane (Saccharum officinarum) clones grown in a subtropical environment. A two-year field experiment was carried out in Santa Maria, RS, Brazil, during the 2007/2008 and 2008/2009 growing seasons. Three sugarcane clones were used: IAC 822045 (early), SP 711406 (median) and CB 4176 (late), in a complete randomized block design, with four replications. Expanded leaf and total leaf (tips) number were determined, and expanded leaf area was measured. The phyllochron (ºC day leaf-1) based on expanded and tip leaf number was stimated, using 10ºC as base temperature. Allometric relationships between individual area and number of expanded leaves were fitted. Phyllochron was analysed as a four-factor experiment: clone, growing season, phyllochron phase, and phyllochron type. The early clone had the greatest potential for growing in a subtropical climate because of higher leaf output and leaf area. |

O objetivo deste trabalho foi comparar o filocrono e a área foliar em colmos individuais de clones de cana-de-açúcar (Saccharum officinarum) cultivados em ambiente subtropical. Um experimento de campo foi conduzido em Santa Maria, RS, durante os anos agrícolas 2007/2008 e 2008/2009. Três clones de cana-de-açúcar foram usados: IAC 822045 (precoce), SP 711406 (médio) e CB 4176 (tardio), em blocos ao acaso, com quatro repetições. Foi medido o número de folhas expandidas e totais (pontas), além da área das folhas expandidas. O filocrono (ºC dia folha‑1), baseado no número de folhas expandidas e totais, foi estimado utilizando 10ºC como temperatura base. Relações alométricas entre a área de folhas individual e o número de folhas expandidas foram ajustadas. O filocrono foi analisado considerando-se um experimento fatorial com quatro fatores: clone, ano agrícola, fase de filocrono e tipo de filocrono. O clone precoce tem maior potencial para cultivo em regiões subtropicais devido ao maior aparecimento de folhas e à maior área foliar.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCNPq, CAPESStreck, Nereu AugustoHanauer, Joana GracielaGabriel, Luana FernandesBuske, Taise CristineLangner, Josana Andréia2011-01-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/8364Pesquisa Agropecuaria Brasileira; v.45, n.10, out. 2010; 1049-1057Pesquisa Agropecuária Brasileira; v.45, n.10, out. 2010; 1049-10571678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/8364/6108https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/8364/4054info:eu-repo/semantics/openAccess2014-11-11T16:36:01Zoai:ojs.seer.sct.embrapa.br:article/8364Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-11-11T16:36:01Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |

Three sugarcane clones were used: IAC 822045 (early), SP 711406 (median) and CB 4176 (late), in a complete randomized block design, with four replications. Expanded leaf and total leaf (tips) number were determined, and expanded leaf area was measured. The phyllochron (ºC day leaf-1) based on expanded and tip leaf number was stimated, using 10ºC as base temperature. Allometric relationships between individual area and number of expanded leaves were fitted.
