Temperature Effects on Soybean Imbibition and Leakage

Temperature effects on soybean imbibition and leakage.

As a part of an analysis of the nature of chilling injury to seeds, measurements were made of the initial linear rates of water entry into and solute leakage out of cotyledons of soybean at various temperatures. Arrhenius plots were approximately linear for water entry into both living and dead cotyledons, with the slope (and activation energy) for entry into living cells being insignificantly ...

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...

Low Temperature Effects on Soybean (Glycine max [L.] Merr. cv. Wells) Mitochondrial Respiration and Several Dehydrogenases during Imbibition and Germination.

The influence of low temperature on soybean (Glycine max [L.] Merr. cv. Wells) energy transduction via mitochondrial respiration and dehydrogenases was investigated in this study during imbibition and germination. Mitochondria were isolated from embryonic axes of seeds treated at 10 and 23 C (control) by submergence in H(2)O for 6 hours and maintenance for an additional 42 hours in a moist envi...

Oyxgen and temperature effects on soybean seed coat respiration rates.

Soybean (Glycine max (L.) Merr) seed coat respiration rates in response to changing O(2) concentration and temperature were examined experimentally and with a mathematical analysis. The experimental observations showed seed coat respiration rates were sensitive to O(2) concentration below 0.25 micromole O(2) cm(-3). There was a steady decline in respiration rates from the saturating O(2) concen...
