Abstract
Samples of barley, maize, rice (paddy) and oats have been germinated in the laboratory under known conditions. Large-scale germination expts. have been carried out on samples of barley, wheat, maize and oats. The degree of germination was followed by acrospire counts and by changes in dry wt. Nicotinic acid assays have been made on the dried powdered material, both by a chemical and a microbiological method, at different stages of germination. In oats a net increase was obtained of 57-108%, Rice gave net increases of 0-52% with different degrees of germination. With wheat, barley and maize no significant increase was obtained. The considerably greater increases reported by American workers may have been due to their obtaining a higher degree of germination, and to some extent also to their omitting to allow for changes in wt. during germination. The chemical method gave satisfactory agreement with the microbiological method with all samples, except the wheat and oats and one sample of un-malted barley, where the chemical method gave higher results.
