Localized infection of cucumber leaves with Colletotrichum lagenarium induced resistance against infection after challenge inoculation with pathogenic fungi, including C. lagenarium and Pythium ultimum var. ultimum. Systemic acquired resistance in the hypocotyl was observed when challenge inoculation was made 4 to 7 days after the first inoculation of cotyledons. Seven days after the first inoculation of a primary leaf, induced resistance against the challenge inoculation in the hypocotyl was also observed. However, the hypocotyl did not develop induced resistance when plants were challenged by a wound inoculation with P. ultimum.
