Analysis of variance (ANOVA) for Diaporthe eres growth (colony diameter; mm), pycnidial conidiomata (n. pycnidia produced/colony) and cirrhi (n. of pycnidia with cirrhi/colony) in different regimes of temperature (5–35°C, steps of 5°C), water activity = 0.99.

Analysis of variance (ANOVA) for Diaporthe eres growth (colony diameter; mm), pycnidial conidiomata (n. pycnidia produced/colony) and cirrhi (n. of pycnidia with cirrhi/colony) in different regimes of water activity (0.83–0.99, steps of 0.03), temperature = 25°C.

Analysis of variance (ANOVA) for Diaporthe eres germination (α spore germination; %) in different regimes of temperature (5–35°C, steps of 5°C), relative humidity (94–100%, steps of 3%).

Dynamics of the growth rate of Diaporthe eres (a) at different T regimes (5–40°C, steps of 5°C) and (b) aw (0.83–0.99, steps of 0.03).
Data collected (black dots) were fitted (dotted line) by a Bete function and a logistic function, respectively (see Table 4 for equation parameters).

Dynamics of Diaporthe eres pycnidial conidiomata production rate at different growing degree days (GDD) as (a) function of T regimes and (b) aw.
Data collected (black dots) were fitted (dotted lines) by a logistic function (see Table 4 for equation parameters).

Germination of α conidia (%) at different: (a) temperatures (5–45°C, steps of 5°C) and (b) relative humidity (94–100%, steps of 3%) regimes.
Data collected (black dots) were fitted (dotted lines) by a Bete and a polynomial function, respectively (see Table 4 for function parameters).

Contour plot curves of Diapothe eres germination (reported as the percentage of germinated α conidia; the darker the color the higher the germination) at different temperatures (5–40°C, steps of 5°C) under different relative humidity regimes (94–100%; steps of 3%).
