연(Pb)에 의한 광계 II 활성억제에 미치는 인산 및 ATP 전처리의 보호효과
Protective Effects of Phosphate and ATP Pretreatment on Pb-Inhibiting Photosystem II Activity
초록
The activity of photosystem II in isolated chloroplast form the leaves of Sedum sarmentosum was measured. The photoreduction rate of DCPIP by photosystem II showed the circadian rhythm with a peak at near midday sample for a continuing fine day and at near afternoon between nidday and sunset sample for a continuing cloudy day in summer. The optimum light intensity of photoreduction by photosystem II in the chloroplast preparation was about 5~9
