The rate of germination defined as the number of biochemical reactions per time throughout the germination process, should not be confused with the percentage of germination that increases from 0 to 100% (when all spores are viable) during the last stage of germination. The rate of germination, arbitrary units, was plotted against the germination time, Fig. 4. When the germination time is equal to 1, half the viable spores had completed germination, but of course this time depends on temperature. A linear and a non-linear rates of germination are shown in solid line, and dotted line, respectively (Fig. 4). The linear rate was characterized by “two” biochemical reactions per quarter of the germination time. The number of biochemical reactions is evaluated by integrating the rate of germination with respect to the germination time. Whatever the rate, linear or not, “eight” biochemical reactions (i.e. squares) are needed for germination to be completed. Let’s consider non-linear, and linear rates of germination at 25 _C, and 10 _C, respectively.
