“…Growing trend of electrical conductivity of seeds with delay in harvest and with decrease in moisture content of seeds after physiological maturity, it indicates that seed possess highest vigour at physiological maturity (H 1 ) afterward it goes on decreasing. Similar results were reported by Gris andPinho (2011), Hampton et al, (1992), Marcos-Filho et al, (1994) and Oliveira et al, (2014).…”

“…The high lignin content in seeds tegument make it difficult the process of water absorption and favor the loss of important substances, affecting the electrical conductivity values (Oliveira et al, 2014). In this study, seeds of the cultivar BRS Valiosa RR, which have high lignin content, showed greater vigor when the plants were desiccated.…”

“…Studying the influence of lignin content in the quality and viability of soybean seeds after storing, Dantas et al (2012) observed that cultivars with higher lignin content showed lower proportion of normal seedling. Oliveira et al (2014) discuss that seeds with higher lignin content absorb less water, which is essential to the metabolic activities that occur during the germination process. In this study, the desiccant Finale® 1/ Times of application of desiccants: 1 st time = 50% seeds water content, 2 nd time = 40% seeds water content, and 3 rd time = 30% seeds water content.…”

Soybean farmers have been using desiccation to anticipate harvesting, however, this technique is frequently questioned when used in seeds production fields, since residues left by desiccants may harm the seeds quality, especially those with fragile tegument. The aim of this study was to evaluate how desiccants applied in different times affect the quality of soybean seeds with different lignin content in the tegument. Plants of cultivars BRS Silvânia RR, BRS Valiosa RR, BRS 245 RR, and BRS 247 RR were desiccated with three commercial herbicides, besides one control treatment, in three application times, when seeds showed 30, 40, and 50% of water content. Seeds quality was evaluated performing the tests of germination, emergence, emergence speed index, accelerated aging, electrical conductivity, tetrazolium and seed yield. The lignin content in soybean seeds has high negative correlation with seed yield and with traits related to the seeds quality. In general, the plants desiccation with the herbicide Finale ® harms the seeds quality.Qualidade de sementes de soja com diferentes teores de lignina obtidas de plantas dessecadas RESUMO: Produtores de soja tem utilizado herbicidas dessecantes para antecipar a colheita, entretanto, essa prática é frequentemente questionada quando utilizada em campos de produção de sementes, uma vez que os resíduos deixados pelos herbicidas dessecantes podem prejudicar a qualidade das mesmas, especialmente daquelas com tegumento frágil. O objetivo nesse estudo foi avaliar como dessecantes aplicados em diferentes épocas afetam a qualidade de sementes de soja com diferentes teores de lignina no tegumento. Plantas das cultivares BRS Silvânia RR, BRS Valiosa RR, BRS 245 RR e BRS 247 RR foram dessecadas com três herbicidas comerciais, além de um tratamento controle, em três épocas de aplicação, quando as sementes estavam com teores de água de 30, 40 e 50%. A qualidade das sementes foi avaliada pelos testes de germinação, emergência, índice de velocidade de emergência, envelhecimento acelerado, condutividade elétrica, tetrazólio e produtividade. Para o teor de lignina das sementes de soja há alta e negativa correlação com a produtividade e os caracteres relacionados à qualidade fisiológica das sementes. A dessecação das plantas com o herbicida Finale ® prejudica a qualidade das sementes.

“…Lignin is a major factor influencing seed quality, including germination, shattering, hard-seed, water permeability, and resistance to seed deterioration. For example, de Oliveira et al ( 2014 ) concluded that higher lignin content in the pod and in the seeds may contribute to the decrease in seed deterioration from moisture. Alvarez et al ( 1997 ) observed similar results among the cultivars, with the greatest lignin content in the seed coat for the seeds of the soybean cultivars.…”

Seed Nutrition and Quality, Seed Coat Boron and Lignin Are Influenced by Delayed Harvest in Exotically-Derived Soybean Breeding Lines under High Heat

The timing of harvest is a major factor affecting seed quality in soybean, particularly in Midsouthern USA, when rain during harvest period is not uncommon. The objective of this research was to evaluate the effects of time of harvest on soybean seed quality (seed composition, germination, seed coat boron, and lignin) in high germinability (HG) breeding lines (50% exotic) developed under high heat. The hypothesis was that seeds of HG lines possess physiological and genetic traits for a better seed quality at harvest maturity and delayed harvest. A 2-year field experiment was conducted under irrigated conditions. Results showed that, at harvest maturity, the exotic HG lines had higher seed protein, oleic acid, sugars, seed coat boron, and seed coat lignin, but lower seed oil compared with the non-exotic checks (Control), confirming our hypothesis. At 28 days after harvest maturity (delayed harvest), the content of seed protein, oleic acid, sugars, seed coat boron, and seed coat lignin were higher in some of the HG lines compared with the checks, indicating a possible involvement of these seed constituents, especially seed coat boron and seed coat lignin, in maintaining seed coat integrity and protecting seed coat against physical damage. Highly significant positive correlations were found between germination and seed protein, oleic acid, sugars, and seed coat boron and seed coat lignin. Highly significant negative correlation was found between germination and oil, linoleic acid, seed coat wrinkling, shattering, and hard seed. Yields of some HG lines were competitive with checks. This research demonstrated that time of harvesting is an important factor influencing seed protein and oil production. Also, since high oleic acid is desirable for oxidative stability, shelf-life and biodiesel properties, using HG lines could positively influence these important traits. This result should suggest to breeders of some of the advantages of selecting for high seed coat boron and lignin, and inform growers of the importance of timely harvest for maintaining high seed quality.
