Temperature effects on soybean imbibition and leakage.

Respiratory changes with chilling injury of soybeans.

The leakage of solutes from cotyledons of soybeans (cv. Chippewa 64) was markedly stimulated by a chilling treatment (1 to 4 C) during the 1st minute of imbibition, but chilling after even 1 minute of water uptake resulted in little or no leakage increase. The respiratory rate of soybean particles was reduced more than 60% if a chilling treatment (15 minutes at 1 to 4 C) was given during the fi...

Chilling Stress to Soybeans during Imhibition.

Embryos, excised from seed coats of soybeans (Glycine max Merr. cv. ;Wayne'), leak profusely during the first minutes of imbibition. A discontinuity of temperature/leakage patterns occurs between 10 and 15 C; as embryos imbibe at 10 C or lower, disproportionately more solutes leak out per unit of water imbibed. Short periods of imbibition at or below 12 to 14 C reduce embryo germination and axi...

Transient changes during soybean imbibition.

Air dry cotyledons of soybean (Glycine max Merr. var. Wayne) imbibe water rapidly for about 10 minutes followed by a slower, linear rate of uptake. Leakage of solutes out of the coytledon likewise shows an initial rapid period, followed by a slower, nearly linear rate after 5 to 10 minutes; both the rapid and the steady rate leakage are greater for initially drier seeds. Respiratory activity of...

Characterization of Solute Efflux from Dehydration Injured

Soybean (Glycine max L. Merr) seeds lose their tolerance ofdehydration between 6 and 36 hours of imbibition. Soybean axes and cotyledons were excised 6 hours (tolerant of dehydration) and 36 hours (susceptible) after commencing imbibition and subsequently dehydrated to 10% moisture. Kinetics of the efflux of potassium, phosphate, amino acid, sugar, protein, and total electrolytes were compared ...
