Abstract

This germination in the fungus, causing fruit rot of Litchi chinensis, was 30-35% in distilled water but most of the oospores produced short germ tubes which did not develop further. C. 2% produced 1 or 2 sporangia on each germ tube. Sometimes germ tubes penetrated the oogonium wall but more frequently they emerged through the oogonium stalk and antheridium. Occasionally up to 10 germ tubes emerged from a single oospore, but in most cases only 1 produced sporangia, some of which released differentiated zoospores after chilling. Attempts to establish colonies from the germinating oospores were not successful. These results supported previous reports [RPP 58, 99] that the fungus is a transitional sp. between Phytophthora and Peronospora.
