LONGEVITY OF SOME COMMON FUNGI IN CEREAL SEED

Abstract
Tests made at regular intervals over a period of 10 years on naturally infested seed of wheat, oats, and barley that had been held in storage showed that most of the seed, while retaining its germinability, became free from viable fungi before the end of the storage period. Alternaria tenuis sensu Wiltshire in all three crops, Helminthosporium sativum P.K. & B. in wheat and barley, and Septoria nodorum Berk, in wheat died out comparatively rapidly. H. avenae Eidam in oats and H. teres Sacc. in barley lost their viability slowly and since, by the end of the storage period, most of the microorganisms associated with them in infested kernels were dead, these two fungi could generally be recovered in pure culture.
