“…Similar results were observed by Ribeiro et al (1994) on germination of maize seeds coated with Zn and B and for sorghum seeds (Yagi et al, 2006) and rice (Funguetto, 2007) covered with Zn. However, several authors report that the seed coating with these micronutrients either applied alone or in combination, does not affect the germination (Ohse et al, 2000;Masuthi et al, 2009;Tavares et al, 2013a;Tavares et al, 2013b;Tavares et al, 2013c;Arjmand et al, 2014;Oliveira et al, 2014).…”

“…A high concentration of salts is characterized as a stress factor for plants, since this salinity entails reducing the osmotic potential which therefore favours the retention of water in order to make it less available for plants (Ribeiro et al, 2001). Thus, with increasing salinity occurs a decrease in osmotic potential, making water absorption by the roots more difficult (Amorim et al, 2002).…”

“…Além disso, a planta do girassol, os grãos, os restos da cultura e os subprodutos gerados na extração do óleo podem ser usados na alimentação animal. É uma cultura de ampla adaptabilidade climática, alta tolerância à seca e alto rendimento de grãos e de óleo (Prado & Leal, 2006); contudo, enquanto para várias culturas são encontradas, na literatura, informações sobre o grau de tolerância ao estresse salino, no caso do girassol poucos são os trabalhos referentes aos efeitos da salinidade da água de irrigação e, ou, do solo nos diferentes estádios de desenvolvimento dessa cultura (Ribeiro et al, 2001;Dickmann et al, 2005).…”

“…A água é osmoticamente retida na solução salina, de forma que o aumento da concentração de sais a torna cada vez menos disponível para as plantas (Ribeiro et al, 2001). Assim, com o aumento da salinidade ocorre diminuição do potencial osmótico do solo, dificultando a absorção de água pelas raízes (Amorim et al, 2002;Lopes e Macedo, 2008).…”
