Cucumber cultivar ‘Poinsett 76’ exhibits age-related resistance to P. capsici. a Fruit length and disease rating (DR) as a function of fruit age. Fruit were ranked on a 1–9 DR scale (1 = no symptom; 9 = extensive mycelial growth and sporulation) at 5 days post-inoculation. The dotted line at DR = 3 represents localized necrosis. Points are means of 5–6 fruit. Error bars represent +/− standard error of the mean. b Representative fruit and disease progression at 5 dpi. c Fluorescently labeled P. capsici on < 8 dpp cucumber fruit at 4 (left) and 72 (right) hpi. sp. – spore; gt – germ tube; ap – appressoria; spg – sporangia
