Resumo: The objective of this work was to evaluate the proline content of sunflower (Helianthus annuus) cultivars, in the conditions of natural water deficit in the Brazilian semiarid region. Thirteen cultivars were sown in experiments set in three sites in the Brazilian Northeast. Proline content was determined on leaves from plants at the R4–R5 stage. Significant differences among cultivars occurred only where water availability was lower. Proline averages ranged from 3.47 to 17.41 µg g-1. The sunflower cultivars BRS387, BRS323, and BRS324 showed the greatest proline contents with 54.74, 46.27, and 35.16 µg g-1, respectively. These are the cultivars that accumulate more proline under conditions of a severe water deficit.

Treze cultivares foram semeadas em experimentos estabelecidos em três áreas do Nordeste brasileiro. O teor de prolina foi determinado em folhas de plantas no estádio R4–R5. Diferenças significativas entre cultivares ocorreram apenas onde a disponibilidade de água foi menor. As médias de prolina variaram de 3,47 a 17,41 µg g-1. As cultivares de girassol BRS387, BRS323 e BRS324 apresentaram os maiores teores de prolina com 54,74, 46,27 e 35,16 µg g-1, respectivamente. Essas cultivares são as que acumulam mais prolina em condições de deficit hídrico severo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraEmpresa Brasileira de Pesquisa Agropecuária (Embrapa, 02.12.12.006.00.00)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq, 153064/2017-0)Carvalho, Luciana Marques deAraújo, Stela Braga deCarvalho, Hélio Wilson Lemos deCarvalho, Claudio Guilherme Portela de2018-10-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/26130Pesquisa Agropecuaria Brasileira; v.53, n.8, ago. 2018; 970-973Pesquisa Agropecuária Brasileira; v.53, n.8, ago. 2018; 970-9731678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/26130/14276https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/26130/17807Direitos autorais 2018 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2018-10-19T20:43:08Zoai:ojs.seer.sct.embrapa.br:article/26130Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2018-10-19T20:43:08Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
