“In order to obtain an insight into the damage of thylakoid membranes of spruce (Picea abies) trees with damage of varying intensity, investigations were performed on the content of Q в -protein, cytochrome f, and P-700 in chloroplasts of spruce needles from apparently healthy and from damaged trees”

e1

“The investigations were carried out in 1986 on a 20 to 25-year-old spruce plantation in the Hunsriick mountains and on an 80-year-old spruce plantation in the Westerwald mountains”

e2

“In damaged trees an unequivocal decrease in the content of Q в -protein, cytochrome f, and P-700 was found, even in needle groups that appear visibly green and healthy”

e3

“The amount of cytochrome f decreased by 25% per dry weight (approximately to the same extent as chlorophyll); the content of Q в -protein and P-700, however, were more drastically reduced compared to the control trees (about 40% and 50%, respectively)”

Claim · model-written summary
