| Research Abstract |
Factor of yellow-leaf-spot occurrence induced by high temperature and irradiation in chrysanthemum were investigated. Yellow-leaf-spot was decreased by chitosan or titanium dioxide. ABA treatment increased yellow-leaf-spot. Thus, a possibility that reactive oxygen species cause yellow-leaf-spot occurrence increases. On artificial environment under high temperature and humidity, yellow-leaf-spot could be occurred. Graphics processing could define yellow-leaf-spot degree which made yellow area or color the index.
