“…Under the two potassium acetate treatments, SFW decreased by 41% and 60% and SDW decreased by 44% and 73%, compared to control values (Table 3). These findings agree with the reports of SDW decrease by Ashraf, Nazir, and McNeilly (2001), Kaya, Kirnak, and Higgs (2001), Caines and Shennan (1999), Adams (1988), and Satti and Al-Yahyai (1995) for tomato; Leidi and Saiz (1997) for cotton, and Bar- Tal et al (1991) in corn. According to Çakır (2004), the decrease in SDW in corn might be related to a decrease in leaf surface, causing a reduction of assimilation ratio and shorter stems, resulting from elevated salinity.…”

“…Apesar da salinidade da água de irrigação não ter influenciado as concentrações de N nas folhas e raízes (Figura 2A), o teor deste nutriente nas plantas é afetado pela salinidade do solo e que a absorção e o transporte do nitrato são limitados, em condições de salinidade, devido ao efeito antagônico existente entre o íon nitrato e o íon de cloro (Bar et al, 1997). Por outro lado, a salinidade pode afetar indiretamente o processo de nitrificatação (conversão do N na forma amoniacal a forma nítrica) devido à diminuição no conteúdo de água decorrente do efeito osmótico, ocasionado pelo excesso de sais (Van Hoorn et al, 2001), consequentemente este fato explica a maior concentração de N da parte aérea das plantas estudas.…”

“…Likewise, Bernstein et al (1974) found that increasing solution K from 0.4 to 2 mM did not improve leaf K or yield of corn grown in sand cultures. Bar-Tal et al (1991) reported an increase in the yield of corn grown in sandy soil, but the response was proportional at all salinity levels. These investigators concluded that despite its beneficial effects on increasing K /Na within the plant, K fertilisation did not reduce the deleterious effects of salinity.…”
