Germination rate is one of the quality-control indexes for brown rice. The effects of moisture
content, temperature and storage time on the germination rate of brown rice were investigated
and changes of germination rate during storage were predicted.
The relationship between the germination rate and time was expressed exponentially and
the time coefficient kept constant, independent of temperature and moisture content. The relationship
between the germination rate and temperature was likewise expressed exponentially
and the temperature coefficient kept constant, independent of moisture content. In the relationship
between germination rate and moisture content, the germination rate decreased markedly
when the moisture content exceeded 15.5% and the exponential function was adapted. The germination
rate was then expressed as a function of moisture content, storage temperature and
storage time.
The mathematical model thus developed predicted the change in the rice germination rate
in storage at ordinary temperatures.
