Comparison of two thermal regimes in the inbred line Caturra with different combinations of light intensity and nitrogen fertilization 43 days post H. vastatrix inoculation. (A) Percentage of infected leaves. (B) Quantity of spores per infected leaf area. The quantity of spores per infected leaf area is plotted on a cube root scale in order to present the two thermal regimes on the same plot despite the marked differences between the values. Four treatments were studied Inline graphic/N- Inline graphic/N- Inline graphic/N+ Inline graphic/N+ corresponding to respectively high light intensity (1000 PAR)/low nitrogen fertilization, low light intensity (300 PAR)/low nitrogen fertilization, high light intensity (1000 PAR)/high nitrogen fertilization, low light intensity (300 PAR)/high nitrogen fertilization. The thermal regime 27°C–22°C is in black and the 23°C–18°C regime is in white. The data are means ± SD (n = 4). Within each treatment, means from thermal regimes followed by an asterisk are significantly different according to Student’s test (P < 0.05).
