Some Influences of Hardseededness on Soybean Seed Quality1

Abstract: The effects of the impermeable seed coat characteristic in soybeans (Glycine max (L.) Merr.) on the seed's sponse to field environment, artificial drying, and storage potential were evaluated. Comparisons were made be. tween seed of ‘Dare’ and those of an experimental hardseeded line, D67‐5677‐1 which is similar to Dare in growth type and maturity. Hardseededness was beneficial in maintaining the viability of seed remaining in the field for up to 9 weeks after seed moisture initially declined to 20%. Resistanc… Show more

“…For all these reasons, it may be affirmed that the presence of hard seeds in the seed lots is an interesting characteristic for, as Potts et al (1978) affirmed, genotypes with high frequency of hard seeds proved to be resistant to deterioration in the field. Nevertheless, selecting lines that exhibit hard seeds is not a practical solution since these seeds soak up moisture slowly and germinate irregularly, unless they are scarified.…”

“…However, soybean seed longevity, resistance to deterioration under field conditions and seed size are not always associated (Kuo 1989, Horlings et al1991. Moreover, the presence of as little as 1%-2% of hard seeds in a seed lot could be enough to negate any eventual reduction in field deterioration resulting from slow water uptake imposed by the testa (Potts et al 1978). Thus, legume cultivars with seed coat capable of delaying imbibition, instead of impeding it, were suggested as better alternatives (Kuo 1989, Chachalis & Smith 2000.…”

“…Sementes com tegumentos impermeáveis à água são menos afetadas pelas flutuações do conteúdo de água que podem ocorrer no campo quando se alternam períodos úmidos e secos, após a maturidade fisiológica (Potts et al, 1978).…”
