Aspectos químicos e estruturais da qualidade fisiológica de sementes de soja

Abstract: Resumo -O objetivo deste trabalho foi avaliar os efeitos gênicos aditivos e não aditivos para as características da espessura das camadas da testa e da lignina presente nessas camadas, e verifi car se os caracteres utilizados para avaliação da qualidade fi siológica das sementes de soja se correlacionam com o teor de lignina do tegumento. Foram usadas três cultivares (M-Soy 8400, CD 201, CD 206) de alta e três (CD 215, CD 202, Savana) de baixa qualidade fi siológica, para se obterem sementes híbridas F 1 e F 2… Show more

“…The high physiological quality can be associated with the lignin content. Menezes et al (2009) have observed that the highest lignin content is associated with a higher percentage of normal seedlings in the accelerated aging test. However, there was a negative correlation to the germination rate.…”

“…In another study, using soybean cultivars with lignin contents in the seed coat ranging from 3% to 5%, Menezes et al (2009) found a negative correlation between germination speed and lignin content, and reported that the higher the lignin content in the seed coat the shorter the time for seed germination. These same authors suggested that these results are consequence of a faster repair of membrane systems of the least deteriorated seeds (higher lignin content); thus leading to a faster seedling emergence.…”
