Germinação e vigor de sementes de sorgo forrageiro sob estresse hídrico e salino

Abstract: -Salt and water stress during germination affect the emergence of seedlings in the field and, consequently, the stand of the plants and crop growth. Two experiments were conducted to evaluate the effects of water and salt stress on germination and vigor of seeds of two sorghum [Sorghum bicolor (L.) Moench] genotypes. The seeding was done inside "Gerbox" boxes, on two sheets of "germitest" paper dampened with distilled water (control) or with solutions of polyethylene glycol 6000 to provide the water potentials… Show more

“…Dantas et al (2007) considered this an efficient method for the prediction of the vigor and the differentiation of the salt tolerance of cultivars of bean (Phaseolus vulgaris L.). Studies of sorghum (Sorghum bicolor L., Moench) showed an accentuated decrease in the GSI at a concentration of 75 mM NaCl (Oliveira & Gomes-Filho 2009), supporting our results.…”

“…A salinidade e o déficit hídrico são os fatores abióticos que mais têm afetado negativamente a produção de espécies vegetais de importância socioeconômica nas regiões áridas e semiáridas, devido a irregularidades pluviais que impedem a lixiviação dos sais na superfície dos solos destas regiões (Ab'Sáber, 1999). Esses fatores afetam negativamente a germinação, o desenvolvimento vegetativo das culturas, a produtividade e, nos casos mais graves, causam a morte das plântulas (Oliveira e Gomes-Filho, 2009).…”

“…Masetto et al (2011) also observed increasing reduction in the formation of normal seedlings in the first count of germination of crambe seeds, as the water availability of the substrate decreased, regardless of the water content of the seeds. According to Oliveira & Gomes Filho (2009), water stress can decrease both the percentage and speed of germination, with large variation of responses among the species. Thus, the capacity of the seeds of some species to germinate under water stress conditions guarantees some ecological advantages over the others that are sensitive to drought (Martins et al, 2014).…”
