“…Studies showed that lignin is one of the most important seeds contents related to the resistance of the soybean seeds to pathogens and to absorb water. According to Gris et al (2016), the seeds impermeability afforded by lignin has a significant effect on the capacity and speed of water absorption.…”

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.

“…There is a strong positive correlation between accelerated aging and first-count germination and germination (Table 2). According to some authors, lignin may be associated with susceptibility to mechanical damage Kuchlan et al, 2018), potential deterioration (Baldoni et al, 2013), water absorption capacity, water absorption speed, and impermeability, among others (Gris, Von Pinho, Carvalho, Diniz, & Andrade, 2016;Abati et al, 2022). Also, it may be correlated with electrical conductivity (Panobianco, Vieira, Krzyzanowski, & França Neto, 1999).…”

In soybeans, the integument or seed coat is an important modulator between the external and internal environment. It plays a fundamental role in seed vitality, and its lignin content may influence the seed quality. The objective of this experiment was to evaluate the quality of soybean seeds from a partial diallel and their reciprocals and its relationship with lignin content, seed coat thickness, and deposition location. The seeds were also evaluated for physiological quality through germination and accelerated aging tests. The lignin content was quantified by absorbance, and the integument thickness was analyzed and measured using scanning electron microscopy. The most contrasting cultivars for lignin content were analyzed using fluorescence microscopy and histochemical techniques. Cultivars and their reciprocals differed in seed physiological quality. We found differences in the genotypes for integument thickness. Using histochemical techniques, autofluorescence was observed in the same regions identified as lignified. Positive staining for lignin was observed in the hilum region. Among the genotypes, we found variations in the physiological quality of seeds (germination and accelerated aging test), lignin content, and integument thickness.
