pigment C was from the artificially reddened sugarcane and they were purified by recrystallization from ethylacetate. 2) Any of pigments A, B, C and D was aromatic compounds, of which A was phenol compond containing butenyl group, B flavonol derivative, C and D were spposed to have not only one phenolic oxygen, but also ether or methyledioxide type oxygen. 3) Sugar cane reddening needed sufficient amount of water and little amount of sugar, but not oxygen. 4) The pigments interested in sugar cane reddening were brought about not only by the infection with P. tucumanensis into the sugar cane tissues, but also mixed with the pigments occurring from other various cases. 5) As a result of the investigations of the ealy stage of red rot diseases of sugar cane, as well as the tolerably developing one, it was found that the concentrations of sugar were slightly reduced in spite of an increase in pigment concentration and a decrease in pH. 6) In the reddening sugar cane slice formed by an acid treament, the pignemt concentration increaed with time and reached finally after 11 days about twice as much as that after 4 days. 7) The sugar cane juice treated with acids changed from pink-brown to brown with an increase in concentration, of which hydrochloric acid contributed to form pignemt extremly much more than other acids. 8) However, the pigments formed according to the above mentioned paragraphs (4) and (5) were different from those of the naturally reddened sugar cane. 9) The fungus B which produced red pigments and pinkish yeast A were separated from the sugar cane infected with red rot disease and the former was supposed to be Phoma sp., and the latter to be Candida pulcherrma. 10) The fact that sugar cane of dead tissue didn't redden but rotted indicates that the appearance of red rot disease was closely related with the condition of the sugar cane tissue, i.e. living and dead.","subitem_description_type":"Other"},{"subitem_description":"11) Judging from the facts that the pigments of red rot disease fungi themselves were completely different from those formed in sugar cane tissue by them and that the sugar cane slices inoculated with them reddened more rapidly than those not inoculated, it was found that they didn't take direct part in the formation of pigments and only contribute to promote it. 12) The optimum pH and temperature of sugar cane peroxidase were 7.8 and 50\u2103 respectively. EDTA, ammonium oxalate and potassium cyanide were used as inhibitor against the emzyme activity. The unexpected activiation by the former two agents seemed to be due to the removal of metals acting as inhiditors. The latter inhibitted the activity completely. The effects of Ag^+, K^+, Mg^<2+>, Na^+ on the enzyme activity were found slighty, Ca^<2+>, Fe^<3+>, Zn^<2+> moderately, and Cu^<2+>, Fe^<2+>, Pb^<2+> remarkably. 13) The enzyme activity of each part of sugar cane was almost unchanged and not affected by the existing sugars. 14) The enzyme activities in naturally reddend sugar cane formed small peaks even after 4 days, whereas the artificially reddened a giant maximum peak after 2 days from the cultiavation. 15) Phenol, ferulic acid, p-coumaric acid and other three phenolcarboxylic acid were found as phenolic compounds in the sugar cane tissue, of which phenol and ferulic acid were found to be related in forming the pigments. 16) The paperchromatograms of pigments formed by the autooxidation of phenol were much the same as ones formed by the action of peroxidase on phenol, of which some were identified as the components of artificially or naturally reddened sugar cane. 17) The direct relationship among pigments formed by the action of peroxidae on ferulic acid and red sugar cane pigments was not observed. 18) The main com","subitem_description_type":"Other"},{"subitem_description":"\u7d00\u8981\u8ad6\u6587","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8"}]},"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/20.500.12000/4424"}]},"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":"\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8\u5b66\u8853\u5831\u544a"},{"subitem_1522650068558":"en","subitem_1522650091861":"The Science Bulletin of the Faculty of Agriculture.
