the objective of the study is to determine differences between cucurbits in the pathogenicity of Didymella bryoniae isolated from the naturally infected seeds of cucumber and pumpkin. Primary seedling infection of cucumber (Cucumis sativus L.), oriental melon (Cucumis melo var. makuwa Makino), pumpkin (Cucurbita pepo L.) and watermelon (Citrullus vulgaris Shrad.) occurred on the radicle, hypocotyl and cotyledons and symptoms on each crop were very similar. Infection of the radicle generally caused pre-emergence rot, while infection on the hypocotyl and cotyledons provided further inoculum for infection of the first true leaves and the stem. In cross inoculation tests, all isolates of D. bryoniae could infect cucumber, oriental melon, pumpkin and watermelon at different growth stages and there were not much differences in pathogenicity or susceptibility between isolates of the pathogen and crops tested. The susceptibility of cucumber and pumpkin was markedly influenced by preavalling humid conditions. |
