Outline of Final Research Achievements

In order to develop the ecological agricultural chemicals for growth promotion, the symbiosis of bentgrass with Lepista sordida, which causes “fairy ring”, was investigated, and the technological construction of food plants production under poor environments was studied.
Methanol extract from the root of bentgrass indicated the inducing activity of AHX production. This result suggests that the AHX production is induced by the interaction between plants and basidiomycetes. Under high temperature injury, the productivity of normal fruit of tomato was improved by the administration of AHX or AOH. Moreover, the rice yield was increased by the administration of AOH under low temperature growth condition.
