As defense responses, phenolics, lipid compounds and lignin-like compounds were observed either in the discolored sapwood or in the boundary between discolored and sound sapwood. The lipid compounds were observed on the 3rd day and were very noticeable on the 10th day for Q. glauca, while their presence was confirmed on the 7th day but they were still a localized reaction on the 14th day for Q. crispula. On the other hand, both phenolic and lignin-like compound accumulations in the susceptible species were observed earlier than those in the resistant species. Moreover, hyphae were not observed in sound xylem which was outside the xylem where lipid and lignin-like compounds accumulated. These results indicate that hyphae growth of R. quercivora might be prevented by the accumulation of phenolic, lipid and lignin-like compounds in the xylem, and the speed of lipid compound accumulation might be mostly related to the susceptibility of the four Fagaceae species examined to R. quercivora.", "subitem_description_type": "Abstract"}]}, "item_4_full_name_3": {"attribute_name":

内容記述 | To examine the differences of defense responses to R. quercivora in four Fagaceae species; two susceptible Quercus crispula and Q. serrata and two resistant Q. glauca and Castanopsis cuspidata var. sieboldii, branches inoculated with the fungus were examined histochemically until 14th day after the inoculation. As defense responses, phenolics, lipid compounds and lignin-like compounds were observed either in the discolored sapwood or in the boundary between discolored and sound sapwood. The lipid compounds were observed on the 3rd day and were very noticeable on the 10th day for Q. glauca, while their presence was confirmed on the 7th day but they were still a localized reaction on the 14th day for Q. crispula. On the other hand, both phenolic and lignin-like compound accumulations in the susceptible species were observed earlier than those in the resistant species. Moreover, hyphae were not observed in sound xylem which was outside the xylem where lipid and lignin-like compounds accumulated. These results indicate that hyphae growth of R. quercivora might be prevented by the accumulation of phenolic, lipid and lignin-like compounds in the xylem, and the speed of lipid compound accumulation might be mostly related to the susceptibility of the four Fagaceae species examined to R. quercivora. | |||||
