Abstract
We report the dynamic change of photosynthesis rate of rose leaf after artificial inoculation of black spot disease.
This experiment was scheduled for making up mores quick selection protocol for the high resistance against black spot disease during breeding program of rose.
Photosynthesis in rose cultivars of Tineke and Asami Red (syn. = Rote rose) was daily measured after artificial infection of black spot.
Significant breakdown of photosynthetic activity was appeared in four to seven days after inoculation in Tineke, however, the epidemic change in the symptom appeared after fourteen days.
This physiological disorder, which appeared ahead for the visual observation for the epidemic appearance of symptom, will be useful tool for quick selection of black spot disease resistance breeding in rose.
