Figure 4. Initial infection and planting density.

Figure 4

(a) Inline graphic, the number of asymptomatic plants (out of a total of 1680 plants) after twenty years, as a function of the percentage of trees that are infected initially, Inline graphic. (b) Inline graphic as a function of the density of hosts, when Inline graphic is held fixed at 1%. (c) As Figure 4(b), but showing Inline graphic per hectare. (d) The maximum Inline graphic per hectare (the inset shows the planting density at which this optimum is attained) for a range of values of Inline graphic. (e) The yield per hectare as a function of the density of hosts, when Inline graphic is held fixed at 1%. The inset shows the response of the yield before applying the normalisation by area (i.e. the inset is analogous to (b)). (f) The maximum yield per hectare (the inset shows the planting density at which this optimum value is obtained) for a range of values of Inline graphic. The black symbols on the x-axis of each graph mark default values that are invariant in other scans (i.e. Figures 4(b), 4(c) and 4(e) have Inline graphic fixed at Inline graphic; Figure 4(a) shows results for Inline graphic trees per hectare (Inline graphic)).
