Rd. Vieira et al., Correlation of electrical conductivity and other vigor tests with field emergence of soybean seedlings, SEED SCI T, 27(1), 1999, pp. 67-75
Seeds from six soybean cultivars (Cristalina, IAC 31-Foscarin, IAC-15, UFV-
10, IAC-14 and IAS-5) and from five soybean cultivars (IAC 31-Foscarin, IAC
-15, IAC-14, IAS-5 and Iguacu) were evaluated in 1993 and 1994, respectivel
y, in terms of physiological seed quality by the mechanical damage (MD), st
andard germination (SG), accelerated aging (AA), electrical conductivity (E
C), and seedling field emergence (FE) tests. Significant correlations were
detected between SG, AA and EC and FE. However, in terms of the cultivar or
the year, the degree of association among these parameters can change base
d on the environmental conditions of each year.
