RATES OF ENDOSPERM MODIFICATION DURING MICRO-MALTING OF SOME AUSTRALIAN BARLEYS

The rate and extent of endosperm modification during germination of some Australian varieties varied considerably. Barley of the variety Clipper modified rapidly in the first days of germination, but following longer germination, endosperm modification was similar to or less than other varieties. The addition of more water and the additives gibberellic acid and potassium bromate increased modification with the response depending upon the variety. A total of 23 varieties and experimental barley lines grown at two locations were micro‐malted using additives. Average endosperm modification was estimated to range from 61% to 89%. 1985 The Institute of Brewing & Distillin
