对油橄榄孔雀斑病病原菌形态、人工培养、接种测定和病菌来源进行了研究,经鉴定病原菌为环黑星霉[Spilocaea oleaginea (Cast.)Hugh.]。分生孢子大多双胞,倒梨形至短倒棍棒形,大小19.6—21.2×8.9—9.8μm。分生孢子梗顶端有几个环痕。此病原菌由原产地带进我国,为分布新记录。
The pathogen morphology, artificial cultivation, inoculation assay and germ source were studied. The identified pathogen was Spilocaea oleaginea (Cast.) Hugh.]. Most of the twin conidia, inverted pear-shaped stick to the short stick, size 19.6-21.2 × 8.9-9.8μm. There are several ring marks on the top of the conidiophore.
