“…Submergence under water might also cause seed injury through alteration in metabolism due to anoxia (Roos andPollock 1971, Qrphanos andHeydecker 1968). The activities of a number of dehydrogenases drop quite sharply under anaerobic conditions (Duke et al 1977), and ATP levels also drop (Givan 1968).…”

Germination and growth of unaged (high vigor) and accelerated aged (41°C and 100% RH for 4 days; low vigor) soybean [Glycine max (L.) Merr. cv. Essex] seeds were severely reduced by soaking the seeds under water at 25°C during the first 1 to 8 h of imbibition. Soaking in 30% polyethylene glycol (PEG) did not injure high vigor seeds and improved the performance of low vigor seeds. Soaking in water increased subsequent RQ values and acetaldehyde and ethanol levels. In high vigor seeds, the increase in RQ lasted only 1 h after transfer to aerobic conditions, whereas in low vigor seeds the increase persisted into the second h. Increases in ethanol and acetaldehyde after soaking were more pronounced in low than in high vigor seeds. The data indicate that relatively short periods under water can cause water uptake injury to imbibing soybean seeds and that this injury can be avoided by osmotically reducing the initial rate of water uptake. Seeds whose vigor has declined during accelerated aging show an additional injury which increases with soaking duration and involves alterations in respiratory metabolism including accumulation of acetaldehyde and ethanol to high, and possibly toxic, levels during imbibition.

“…Other workers noted similar deleterious effects of soaking common beans in distilled water. [274][275][276][277] A high negative correlation occurred between seed vigor and the exudation of seed electrolytes (leaching) when soaked in distilled water. 278 Abdul-Buki and Anderson 304 found sugar leaching increased with increasing seed age but not with accelerated aging except where viability was severely reduced.…”

“…The effects of seed soaking injury have been investigated (Eystes 1940, Orphanos and Heydecker 1968, Roos and Pollock 1971. Our results show that germination percentage and radicle length were maximized by soaking 50 cottonseed with 2.0 ml water (Table 1).…”

Effects of exogenous free fatty acid application on percentage germination and radicle length were investigated with more chill sensitive (Pima S-4) and less chill sensitive (Pima S-5) cottonseed (Gossypium barbadense L.) at chilling (14°C) and optimal (34°C) temperatures. Of the organi(f solvents able to solubilize free fatty acids, aqueous solutions as high as 5% dimethyl sulfoxide did not adversely affect germination at 34°C. Palmitic, oleic and linoleic acids (120 fiM) were solubilized in 5% DMSO.At 14°C, percent germination of fatty acid treated Pima S-5 significantly increased, while no difference was observed for Pima S 4. Conversely, radicle length of fatty acid treated Pima S-4 significantly increased especially with oleate and linoleate, while no difference was detected for Pima S-5. Fatty acid supplementation influenced neither germination nor radicle length for Pima S-4 and Pima S-5 at 34°C.
