Qualidade fisiológica e composição química das sementes de soja com variação na cor do tegumento

Abstract: ESMAEL LOPES DOS SANTOS 2 , JOSÉ NIVALDO PÓLA 3 , ALBERTO SERGIO DO REGO BARROS 3 , CÁSSIO EGIDIO CAVENAGHI PRETE 4 RESUMO -A qualidade e a composição da semente de soja estão relacionadas com fatores genéticos, mas podem sofrer influência do meio ambiente. O tegumento, responsável pela proteção dos órgãos internos da semente, normalmente apresenta-se na cor amarela, mas pode sofrer variações de tonalidades através de mutação natural, podendo se apresentar marrom ou preto. O trabalho teve como objetivo verific… Show more

“…However, there was a negative correlation to the germination rate. Santos et al (2007) have found that soybean seeds with brown integument have a higher lignin content, ranging between 4 and 6% of lignin compared to the total weight of the integument, and higher vigor due to the slower rate of soaking. Carvalho et al (2014) have noticed that soybean cultivar seeds with high lignin content in the integument do not necessarily have better physiological quality.…”

“…According to França-Neto et al (2007), the use of soybean genotypes with higher lignin content in the seed coat favors production of higher quality seeds. The lignin, besides increasing seed resistance to mechanical damages, has provided lower hydration speed to the seeds (Santos et al, 2007).…”

“…Meantime, other studies have reported an association between high physiological quality of soybean seeds with high lignin content in the seed coat, like Panobianco et al (1999) and Santos et al (2007). Menezes et al (2009) found positive correlations between the lignin content and the percentage of normal seedlings in the aging test, and a negative correlation for germination speed.…”

“…This can affect the resistance to mechanical damage and physiological quality of soybean seeds, considering their relationships with the lignin content in the seed coat, as reported by Capeleti et al (2005), Panobianco et al (1999) and Santos et al (2007). There are also reports that glyphosate-resistant transgenic soybean plants could be less efficient in the accumulation of Mn than conventional soybean, so they would be more responsive to the use of this micronutrient (Gordon, 2007), but the results are still inconclusive and conflicting as to productivity (Andrade and Rosolem, 2011;Basso et al, 2011;Loecker et al, 2010;Zobiole et al, 2010).…”
