Abstract
12 cv. of grain sorghum were assayed for tannin content at various stages of maturity. Max. tannin values/seed were obtained 25-40 days after half-anthesis in cv. containing tannin. Wide variability in apparent loss of tannin as the grains matured was found between cv., with tannin contents of mature seed ranging from 3-93% of the max. found in the immature seed. Cv. with the max. decrease in tannin with maturity may possibly be similar to low tannin cv. in the nutritional quality of the mature grain, yet provide resistance to seed-eating birds during the immature stages. Drying immature grain at room temp. after either boiling for 3 min or freezing reduced apparent tannin content over untreated controls, but these treatments had little effect on the nutritional quality of the grain
