 ^{a}Bainsvlei 2005/2006 (R^{2} = 0.90; y = 1.8422x + 1.7856); ^{b}Bainsvlei 2006/2007 (R^{2} = 0.92; y = 2.0359x + 2.3363); ^{c}Waterbron 2006/2007 (R^{2} = 0.91; y = 2.1033x + 2.5423); ^{d}combined mean crosspollination across all trial sites (R^{2} = 0.95; y = 1.9509x + 2.2181); ^{e}Bainsvlei 2005/2006 (R^{2} = 0.80; y = 1.5652x + 2.2691); ^{f}Bainsvlei 2006/2007 (R^{2} = 0.92; y = 1.7271x + 2.6474); ^{g}Waterbron 2006/2007 (R^{2} = 0.91; y = 1.8318x + 2.9335);^{h}combined high crosspollination across all trial sites (R^{2} = 0.97; y = 1.7547x + 2.7405); ^{i}the datasets were combined and the means calculated with a 90%, 95% and 99% CI, respectively; ^{j}isolation distances derived from means from the combined dataset with a 90% CI (R^{2} = 0.92; y = 1.2445x + 1.6078); ^{k}isolation distances derived from means from the combined data with a 95% CI (R^{2} = 0.95; y = 1.2401x + 1.5719); ^{l}isolation distances derived from means from the combined data with a 99% CI (R^{2} = 0.96; y = 1.2493x + 1.55). Theoretical isolation distances (metres) are derived from 1.0%, 0.1%, 0.01% and 0.001% crosspollination using logarithmic equations for mean crosspollination and combined means over distance compared to high crosspollination over distance for Bainsvlei 2005/2006 (BV06), Bainsvlei 2006/2007 (BV07) and Waterbron 2006/2007 (BV07) (P << 0.01). The theoretical isolation distances were also calculated after combining the data sets from means with a 90%, 95% and 99% confidence interval (CI), respectively.
