Abstract

Summary: Mechanical damage to hyphae of some A compatibility-type spp., by cutting with a cork borer or scalpel, can induce formation of pairs of gametangia followed by oospores. The A compatibility types examined did not respond significantly to damage. Two homothallic species of Phytophthora responded to mechanical damage by forming increased numbers of gametangia. Induction of gametangia in A following damage depends on the composition of the medium. Injury produced by HO or ether also induced sexual reproduction in A It is concluded that the mechanism by which gametangia are induced in A Phytophthora strains by may involve damage and that production of oospores in response to damage may be significant in the survival of Phytophthora.
