ABSTRACT
Among pathogen attributes, conidia germination, germtube growth, and the production of infection structure are all influenced at high CO
as fewer conidia germinate and produce appressoria and the growth of germtube and appressoria production are delayed by several hours (Hibberd et al. 1996; Chakraborty et al. 2000). These contribute to a longer incubation period (time between inoculation and symptom expression) and a reduced disease severity at high CO
,
but the latent period (time for the host tissue to become infectious) remains unchanged, as growth within host tissue is unaffected.
