馬鈴薯疫病菌に対する感受体の過敏感現象とATPアーゼ活性について

This paper deals with the preliminary experiments on the relation between the ATPase activity of potatoes and hypersensitivity of potatoes to the invasion of Phytophthora infestans.
Zoospores of Phytophthora infestans (Race. 0) were inoeulated on the leaves of resistant interspecific hybrid 41089-8 and Kennebec and susceptible Norin No. 1. ATPase activity was examined by the histochemical procedure and by the quantitative analyses of the inorganic P in potatoes inoculated with both compatible and incompatible races of Phytophthora infestans. The raising of ATPase activity was recognized in potatoes of interspecific hybrid which have non-affinity to the invasion of definite race of Phytophthora infestans.
From these results, the hypersensitivity seems to have some connection with the ATPase activity in the suscept.
