The order of high-temperature tolerance of each morphological stage was hyphae <initials <white sclerotia <immatured sclerotia <matured sclerotia. Matured sclerotia, in particular, resisted to 3-7 Chigher temperature than other stages. Rhizoctonia solani was more tolerant than Sclerotinia sclerotiorum in every stages. As ultraviolet irradiation to each stage, hyphae became extinct for 15-30min. irradiation, whereas initials for 3-5 days irradiation in Rhizoctonia solani and for 1-2 days in Sclerotinia sclerotiorum. On the other hand, all stages on and after white sclerotia survived even at the irradiation applied for 10 days. Initial which is formed by hyphal branching followed by aggregation and interweaving changed to more tolerant to UV than hyphae, suggesting that striking phygiological turning could happen on the initials stage. Matured sclerotia of two fungi died at pH 4-5,but survived above pH 6.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学農学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/3935"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0370-4246"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250548"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学農学部学術報告"},{"subitem_1522650068558":"en","subitem_1522650091861":"The Science Bulletin of the Faculty of Agriculture.
