Growth models of silver fir on Mont-Ventoux, France, following comparisons of observed and simulated growth (Mean BAI) between infected (N = 12) and uninfected trees (N = 8) using Student’s t test (p < 0.05). The x-axis indicates the infection level (class 0, absence of mistletoe; class 1, low infection; class 2 and 3, moderate and strong infection). Different letters indicate a significant difference. NS non-significant; *p < 0.05; the error bars represent the standard error
