Some of the investigators in Japan reported in the past that a causal fungus of the bulb rot is the Fusarium. However, the present writer will not agree to this opinion. Not only on the bulb does a disease by the Phytophthora occur but also on all such parts as leaf, stem, flower, and root of tulip taking on water-soaked dull color. The lesions of the leaf blight become, however, gray-white under dry weather like the \"white tip\" of leek as seen in Europe. Pure isolation of the fungus, Phytophthora, causing blight and rot of tulip, must carried out under the temperature 20℃ or below, inasmuch as diseases of tulip take place during a period of low temperature in Japan. Rots of the bulb in storage are severely observed in a cool period of the autumn, but not in the summer. The tulip disease by the Phytophthora occurs during a period of low temperature from the autumn through the spring, being especially severe in open fields in March and April. Zoosporangia of the causal fungus is not usually observed on the lesions of tulip and the lesions will be covered soon with bacteria and then Fusarium. The fungus in the present observation grows between the temperatures of 0℃ and 28℃ with the optimum temperatures 15℃ and 20℃. Oospores are formed abundantly in the various media, but zoosporangia are done very few. When the mycelium of the fungus growing in any liquid media is transplanted to the cool water, many sporangia will be formed in two or three days. The forgoing experiments on the fungus, Phytophthora, of tulip lead to the conclusion that the disease should be a new kind to tulip in Japan and the organisms be identified as Phytophthora porri Foister which causes a blight and rot of scallion, of which the writer reported previously. And chlamydospores are founded in the experiments for the first time.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_3_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00062275","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00757373","subitem_source_identifier_type":"PISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"桂, 琦一","creatorNameLang":"ja"},{"creatorName":"カツラ, キイチ","creatorNameLang":"ja-Kana"},{"creatorName":"Katsura, Kiichi","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KATSURA, KIICHI","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-20"}],"displaytype":"detail","filename":"KJ00000078853.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"KJ00000078853.pdf","url":"https://kpu.repo.nii.ac.jp/record/4854/files/KJ00000078853.pdf"},"version_id":"79791717-8bc9-4e57-a3c3-ce323ac537c7"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper"}]},"item_title":"チューリップの白色疫病に関する研究 I : 疾病とその病原菌について(農学部門)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"チューリップの白色疫病に関する研究 I : 疾病とその病原菌について(農学部門)","subitem_title_language":"ja"},{"subitem_title":"Studies on the blight and rot of tulip caused by Phytophthora porri FOISTER.
