Resumo: This study evaluated the viability of hidration/dehydration techniques to overcome the deleterious effects of salinity on cotton (Gossypium hirsutum L.) cultivars BR-1, Deltapine Smooth Leaf and Texas during germination. Before sowing, one group of seeds of these three cotton cultivars received no previous treatment (treatment A1). Another group was hydrated for six hours and slowly dehydrated for fourteen hours (treatment A2). A third group, besides hydration/dehydration was subjected to six hours of controlled rehydration (treatment A3). Seeds of cotton cultivars divided in these three treatments were sown in distilled water or NaCl solution of -0.8 MPa. Hydration/dehydration or hydration/dehydration/rehydration treatment reduced the deleterious effects of salinity on germination and root growth of cultivars. The significance of hydration/dehydration of seeds of cotton to overcome the deleterious effects of NaCl by increasing the percentage of seed germination and stimulating root development is discussed.

Antes da semeadura, um grupo de sementes das três cultivares de algodão não recebeu nenhum tratamento prévio (tratamento A1). Um segundo grupo foi hidratado por seis horas e lentamente desidratado por quatorze horas (Tratamento A2. Um terceiro grupo, além de hidratação por seis horas e desidratação por quatorze horas, foi também submetido a um processo controlado de reidratação por seis horas (tratamento A3). Sementes de algodão divididas nestes três grupos foram semeadas em água destilada ou solução de NaCl de -0,8 MPa. Os tratamentos de hidratação/desidratação ou hidratação/desidratação/reidratação minoraram os efeitos deletérios da salinidade na germinação e no crescimento do sistema radicular das cultivares. Discute-se a importância da hidratação/desidratação de sementes de algodão na superação dos efeitos deletérios do NaCl pelo aumento da percentagem de germinação das sementes e estímulo ao desenvolvimento das raízes.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFerreira, Luiz Gonzaga R.Rebouças, Maria Altair A.1992-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/3689Pesquisa Agropecuaria Brasileira; v.27, n.4, abr. 1992; 609-616Pesquisa Agropecuária Brasileira; v.27, n.4, abr. 1992; 609-6161678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/3689/980info:eu-repo/semantics/openAccess2010-03-11T11:34:58Zoai:ojs.seer.sct.embrapa.br:article/3689Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-03-11T11:34:58Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
