“…This genotype is considered more susceptible to deterioration as a result of moisture and mechanical damage, precisely because of the lower resistance of its coat due to a lower concentration of lignin (BAHRY et al, 2015;MERTZ et al, 2009). This as well may lead to less control over the entry of water in the initial stage of seed soaking, not allowing an adequate reorganization of the membrane system, causing irreversible damage to the embryo and, consequentially, reducing the number of normal seedlings (ZIMMER, 2012).…”

“…Work carried out to improve the quality of soybean seeds has found some responses in the coat that can contribute to minimizing the problems related to this issue (MA et al, 2004;MENEZES et al, 2009;MERTZ et al, 2009;RANATHUNGE et al, 2010;SANTOS et al, 2007;SHAO et al, 2007).…”

“…Some researchers have found that black colored coats present a semi-impermeability to water, which confers greater resistance to deterioration in the field after physiological maturity; slower soaking during the germination process, allowing better reorganization of the membrane system; and, less mechanical damage in comparison to yellow and permeable coats which are characteristics of the cultivar traditionally cultivated (MERTZ et al, 2009;SANTOS et al, 2007).…”

“…However, despite the knowledge of the properties of black colored coats, such as semi-permeability, greater epidermal thickness, higher concentrations of phenolic compounds and lignin, which confer on them superior characteristics in relation to the genotypes with yellow coat (ANDRADE, 2012;BAHRY et al, 2015;MERTZ et al, 2009;SANTOS et al, 2007). Research aimed at elucidating other attributes of this type of seed is not adequately explored.…”

-The attributes that confer seed quality can largely be considered dependent on the coat. The aim of this study was to evaluate the quality and hydration pattern of the seeds of four contrasting soybean genotypes for the coats characteristics; BMX Potência RR and CD 202 with yellow coats and IAC and TP with black coats. The first stage of the study consisted of seed multiplication in the 2012/2013 harvest. After storage for five months at a temperature of 17 ºC and a relative humidity of 50%, the seeds were subjected to the following tests: germination, first count and seedling height, with and without immersion of the seeds, emergence in soil, emergence speed and germination index; electrical conductivity; thousand weight seeds and imbibitions of seeds. The design was completely randomized, with five replicates. The data was subjected to variance analysis and the means compared using the Tukey test at a 5% level of probability. Regression analysis was used for the seeds imbibitions test. Genotypes with black coats (especially IAC) presented better physiological quality in relation to genotypes with yellow coats. The latter had greater thousand weight seeds. BMX Potência RR presented greater hydration than the other genotypes in the first hours of imbibitions and TP, the least. Genotypes with black coats emitted a radicle faster than the yellow coats genotypes.Key words: Seed performance. Glycine max. Hydration. Thousand weight seeds.RESUMO -Os atributos que conferem a qualidade das sementes podem ser considerados, em grande parte, dependentes do tegumento. O objetivo do trabalho foi avaliar a qualidade e o padrão de hidratação das sementes de quatro genótipos de soja contrastantes para as características de tegumento; BMX Potência RR e CD 202, de tegumentos amarelos e, IAC e TP, de tegumentos pretos. A primeira etapa do estudo constou da multiplicação das sementes, na safra 2012/2013. Depois de cinco meses armazenadas à temperatura de 17 ºC e 50% de umidade relativa do ar, as sementes foram submetidas aos testes de germinação, primeira contagem e comprimento de plântula, com e sem imersão das sementes; emergência em solo; índice de velocidade de emergência e germinação; condutividade elétrica; massa de mil sementes e embebição das sementes. O delineamento foi o inteiramente casualizado, com cinco repetições. Os dados foram submetidos à análise de variância e as médias comparadas pelo teste de Tukey, ao nível de 5% de probabilidade. Para o teste de embebição das sementes aplicou-se análise de regressão. Genótipos de tegumento preto (em especial o IAC) apresentam maior qualidade fisiológica em relação aos de tegumento amarelo. Estes últimos possuem maior massa de mil sementes. BMX Potência RR apresenta hidratação maior que os outros genótipos nas primeiras horas de embebição e TP, a menor. Genótipos de tegumento preto emitem a radícula mais rápido que genótipos de tegumento amarelo.Palavras-chave: Desempenho de sementes. Glycine max. Hidratação. Massa de mil sementes.

Sweet corn is one of the most popular vegetables worldwide. However, traditional shrunken2 (sh2)-based sweet corn varieties are poor in nutritional quality. Here, we analysed the effect of (1) β-carotene hydroxylase1 (crtRB1), (2) opaque2 (o2) and (3) o2 + crtRB1 genes on nutritional quality, germination, seed vigour and physico-biochemical traits in a set of 27 biofortified sh2-based sweet corn inbreds. The biofortified sweet corn inbreds recorded significantly higher concentrations of proA (16.47 μg g−1), lysine (0.36%) and tryptophan (0.09%) over original inbreds (proA: 3.14 μg g−1, lysine: 0.18%, tryptophan: 0.04%). The crtRB1-based inbreds had the lowest electrical conductivity (EC), whereas o2-based inbreds possessed the highest EC. The o2 + crtRB1-based inbreds showed similar EC to the original inbreds. Interestingly, o2-based inbreds also had the lowest germination and seed vigour compared to original inbreds, whereas crtRB1 and o2 + crtRB1 introgressed sweet corn inbreds showed similar germination and seed vigour traits to their original versions. This suggested that the negative effect of o2 on germination, seed vigour and EC is nullified by crtRB1 in the double mutant sweet corn. Overall, o2 + crtRB1-based sweet corn inbreds were found the most desirable over crtRB1- and o2-based inbreds alone.
