Jl. Woods et al., PREDICTING THE GERMINATIVE ENERGY OF DORMANT MALTING BARLEY DURING STORAGE, Journal of the Institute of Brewing, 100(4), 1994, pp. 257-269
The management of dormant barley stocks for malting requires a method
of predicting germinative energy under given conditions during storage
. A method of quantifying the relationship between storage temperature
and the dormancy period is developed based on probit analysis. The ex
perimental data were obtained using Triumph barley. The conditions cov
ered in the experimental work were 8-degrees-C to 38-degrees-C storage
temperature at 12% moisture content, wet basis. Combined use of the d
ormancy model with an existing viability model allows the prediction o
f germinative energy as a function of storage temperature and moisture
content given the initial germinative energy and capacity values. The
effects of storage temperature on the variation in germination over t
ime of dormant barley samples with various initial germinative capacit
ies, and storage moisture contents are investigated using the model. T
he results indicate that storage at moisture contents below 12% give s
ignificant increases in the germination level that can be achieved.
