The definitions, values and dimensions of model parameters^a.

a<p>Parameter values were taken from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0091910#pone.0091910-Hobbelen1" target="_blank">[18]</a>, except for parameters , , and . The estimation of the values of these parameters is described in the text.</p>b<p>The character ‘t’ represents degree-days.</p>c<p>Lower leaves are leaves that emerged before leaf 3, when counting down from the flag leaf (flag leaf = 1).</p>d<p>A compound parameter which combines the infection efficiency and the probability of a spore landing on the upper leaves of the canopy (see text).</p>e<p>Dimensionless.</p>f<p>See the text for the range of values of parameters , and in the simulations.
