GooDSELL LARGE acreage of hybrid seed corn is grown in an area where there is considerable hazard from early freeze damage to seed viability. The reduction in seed viability as a result of freeze injury may vary according to the maturity of the seed parent, the severity of the freeze, the resistance of the particular seed parent to freeze injury, and other factors. Since standard germination tests require a week or longer for their completion, a test which will give an accurate index to seed corn viability within 48 hours after a hard freeze may be useful, as such a test would enable the seed corn producer to select fields with seed of suitable viability for immediate harvest and processing and to avoid undue effort and expense on seed which may later prove unsuitable for planting purposes. · A number of experiments have been reported on the use oftetra­ zolium salt solutions for testing germinability of seeds. By means of comparative testing, viable seeds were shown to stain a brilliant red color in the embryonic tissues when properly
