“…Six soybean cultivars were evaluated and divided into two groups, first classified according to Moreno et al (2019) by germination and vigor tests (accelerated aging, first germination count, final count germination, and controlled deterioration) in a study carried out previously. Group one (G1) had three cultivars with seeds of high physiological quality (CD 201,CA 115,and MS 8400) and group two (G2) had three cultivars with seeds classified as low physiological quality (CD 202, Syn 1263, andSyn 1279).…”

“…There are reports of the influence of genotypes on the physiological quality of soybean seeds (Menezes, Von Pinho, José, Baldoni, & Mendes, 2009;Carvalho, Mavaieie, Oliveira, Carvalho, & Vieira, 2014;Castro, Oliveira, Lima, Santos, & Barbosa, 2016, Moreno et al, 2019.…”

“…The use of soybean genotypes with higher lignin content in the seed coat favors the production of higher quality seeds (França Neto et al, 2016) because it affects the degree of resistance to mechanical damage (Kuchlan, Kuchlan Onkar, Ramesh, & Husain, 2018), the process of water absorption (Abati et al, 2022), and moisture damage in soybean seed cultivars (Huth et al, 2016). Many experiments have been carried out to understand the influence of lignin in the seed coat of soybean seeds and the physiological characteristics associated with lignin content (Castro et al, 2019;Botelho et al, 2019;Baldoni, Von Pinho, Fernandes, Abreu, & Carvalho, 2013;Carvalho, Oliveira, & Caldeira, 2014). Ultrastructural and histochemical analysis of these integuments can elucidate aspects related to lignin and the physiological quality of soybean seeds…”

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.

The selection of soybean genotypes with seeds of high physiological quality is key to increasing the likelihood of establishment and success in the field and thus reaping higher yields. The aim of this study was to evaluate the genetic control of the physiological quality of soybean seeds from a partial diallel cross. Six previously selected soybean cultivars, group 1 (CD 201, CA 115, MS 8400) and group 2 (CD 202, Syn 1263, Syn 1279), were intercrossed by a partial diallel cross, totalizing 24 treatments. Seeds from these cultivars and crosses were evaluated for seed physiological quality based on germination tests, first germination count, accelerated aging, seedlings emergence, and emergence speed index. The lignin content in the soybean seed coat was evaluated. The effects on general and specific combining ability and reciprocal effects were analyzed. There were significant additive and non-additive effects of the genes on the seed quality traits and pronounced effects on the reciprocal traits, which suggest the presence of a maternal effect. Lignin content was not correlated with the physiological test results in the studied genotypes.
