THE KERNELS ENDOSPERM COLOUR OF A LONGITUDINAL SECTION OF MALTING BARLEY AND THE SIMILARITY AMONGST VARIETIES PART II. COLOUR CHANGES AFTER GERMINATION AND HEATING

The previous of our research showed that the endosperm colour of 13 varieties depends of differences in similarity of hordeins. The endosperm colour is not specific for varieties of high similarities of hordeins. Do changes in microstructure of endosperm as a result of 24 hours germinating and heating increase the differences of colour amongst varieties which are more similar in hordeins electrophoregrams. The endosperm colour of 13 varieties was measured using DIA System LUCIA G. It was proved that germinating and heating significant differences in colour of endosperm of some varieties with highly similar hordeins. It suggests the possibility of evaluating the variety uniformity of malting barley batch, as well as predicting the malting quality of grains using evaluation of endosperm colour after one day germinating and heating of grains.
